Yet this study was ignored by the MHRA in its 2012 York report which said mesh complications were 1-3%
In Jan 1998 the TVT is C. By October 1999, the TVT is still rated as C pending results of RCTs. Just three months later in January 2000 The TVT is upgraded to A – with no long term large scale RCTs.

BSUG Database is not fit for purpose because…
In 2012 BSUG accepted the new international 5 code ICS/IUGA mesh complication code generator system. Surgeons can then report specific types of problems and how long it took for them to appear. BUT…this information has never been analysed and published by BSUG. Why?
To work, a database must be independent from surgeon societies.

CTV Canada has blind spot on medical device safety
In 2017, a total of 22 Canadian physicians of varying specialty, region, organisation and career stage perceived Adverse Medical Device Event AMDE reporting as unnecessary, not possible or futile due to multiple factors. Physicians viewed AMDEs as an expected part of practice that they could manage by switching to different devices or developing work-around strategies for problematic devices. Their “behaviour is reinforced by limited healthcare system capacity and industry responsiveness.”

Failing system: Consultants cannot add a mesh complication to the BSUG database if the original mesh operation was carried out by another surgeon. They have to gain the patient’s consent to contact the original surgeon. Which means a vast number of complications will not be logged. Recording Mesh Graft Complication Surgery on the BSUG Database
Oxford release a disparaging report that says mesh complications are more likely psychological issues
Natalia Price, Simon Jackson et al publish paper Sep 2018 that says “Patients may attribute highly diverse symptoms due to mesh insertion, including chronic pelvic pain, chronic fatigue, fibromyalgia and pain distant from the pelvis. There is limited evidence to support the causality of mesh in these distant symptoms. Patients may also have psychological morbidity rooted in anxieties about long- term harm from mesh”
Conflicts of interest in medicine
Fiona Godlee, editor of the British Medical Journal, said in this article: “We don’t let judges or journalists take money from the people they are judging or reporting on: we shouldn’t let doctors do this either.

UK trials “new mesh” since 2016
New mesh” has been trialled in England and Northern Ireland since 2016. They are trialling it as they admit shrinkage with the polypropylene mesh is a problem.
“The sling being studied is DynaMesh®SIS soft, made of polyvinylidene fluoride (PVDF) which has improved biocompatibility with tissues, meaning reduced scar formation and less mesh shrinkage.”
It is poly so is still plastic and still introduces a foreign body into a clean, contaminated field using large hooks and inserted blindly.
There are 11 centres. It is currently in use in four. Norwich (main research centre), Antrim and Belfast in the UK and Munich in Germany.
It will be introduced in London, Cambridge, Wirral, Solihull, Huntingdon and Kilmarnock in the UK and Wurzbug in Germany.
Classic short term follow up of one year then, then for a further year by postal questionnaire. Clinical follow up is at 3 and 12 months post operatively and as required if any concerns.

This article describes the VUE trial, but does not show any results despite being published in 2016 . The Vue Trial began recruiting in 2013 across 40 centres. Six month and 12 month reviews were done. We are now in May 2018.. Not even one year results have been published. Five years on it should’ve published full results by February 2018.

KS Olah 2003 Had the Ward Hilton study not been published it is likely that the Vaginal Colposuspension would have become the gold standard as per this paper. Or laparoscopic Burch colpo would have become gold standard. Instead mesh took off and surgeons lost their traditional skills
Back to the future with Colposuspension
This paper by Jan et al says there is a rise in the traditional Burch colposuspension operation to fix SUI with the rise in concerns of mesh risks. Great news. The downside is the surgeon leaves in a “failed” TVT, leaving in the plastic, while hitching up a woman’s insides.

This is a “seriously difficult report to understand” and there are “several limitations” that need to be taken account of.
The costs the NHS are considerable, despite the fact that the costs we have outlined underestimate the true costs to the NHS.
The actual costs, however, to women are not revealed by this report. There is no information on quality of life and no information on long-term morbidity. The report does, however, tell us that the long-term complications persist and worsens over time.

Bilal Farhan et al say risk of mesh complications from vaginal prolpase mesh is 35% That is one in three women suffering life altering complications. Overall, 21% women underwent mesh-related reoperation.. The rate of mesh-related complication was 34%, while ; 30% had mesh extrusion into the vagina and 1% had mesh erosion into the bladder or rectum.
Looking at studies from 2005 to 2012 Mesh erosion up to 33% & average shrinkage of 25-30%
1. A mesh erosion rate of up to 33%
2. Pain of up to 40% in TVTO & 24.4% in prolapse
3. Loss of sex life 9.1%
4. Retraction of tissues surrounding the mesh with average shrinkage 25–30% in surgery on rats. It may reach 40% of the initial surface of the implant. One study found 19.6% reduction in the length of mesh.
“It is important to cautiously analyse results of various published studies in the literature”

This is the substantial equivalent notification for this sling. It has been approved cos it is found to be substantially equivalent to hernia mesh, TVT and other regular mid urethral slings. Yet the Single Incision Mini Sling is a very different concept. https://www.accessdata.fda.gov/cdrh_docs/pdf2/K023898.pdf

Complications don’t show
This study by Yeng, Raz et al says major complications of midurethral slings are more common than appear in literature. Devastating complications involving urethral and bladder perforations can present with mild urinary symptoms and thus are likely under‐diagnosed and under‐reported. Most of these cases need to be managed with additional reconstructive surgery. Neurourol. Urodynam. https://onlinelibrary.wiley.com/doi/abs/10.1002/nau.20357
German surgeons unimpressed by mesh
German study by Hampel says German surgeons “remain unimpressed.” that the traditional surgery skills to fix prolapse and SUI have been lost to mesh – without evidence to back it up – as it has been pushed as the cheap quick fix. But at what cost?
European Urology Burch vs slings. An example of p hacking aka research cheating – where figures are massaged to fit desired outcomes. In this case, in 2002, Ward & Hilton compared the old fashioned Burch operation to mid urethral mesh slings (MUS) and found they were about the same in effectiveness. However in 2017 Fatteh et al looked at the same study and concluded MUS were better. How? By looking at secondary outcomes instead of primary – changing goal posts. They also included a study that was not a true comparison of an open Burch colposuspension vs mesh in a study by Valpas.
The Valpas study added mesh into the Burch operation all done via keyhole rather than open surgery, which has more adverse events – so of course a MUS would come out as better by comparison.
The MHRA admit that there are austerity measures in the medical device department.
BJOG The Humpty Dumpty theory by Paul Hilton
The problem with research
Many studies are short term, or the early studies were on animals that can’t speak of pain or lost sex lives. Many report authors have conflicts of interest.
Animal studies proved mesh implants cured the problem but they did not show the devastating quality of life complications mesh can cause.
There is p hacking which is medical speak for research fraud where figures are massaged to fit desired outcomes by amending trial protocol.
Other problems with trials are that the questionnaires are designed to not capture worsening or new onset of problems – in other words they do not properly ask about a woman’s quality of life after a mesh operation – so this is not captured in any of the data. Many women on Sling The Mesh would show as a success in Quality of Life questionnaires as they are “cured”. So a woman could be in a wheelchair, having had a number of mesh removals and in terrible pain, but if the mesh has fixed eg her incontinence and she no longer has to wear pads then in trial terms she is deemed a success.
Many include short term trials like the York report .
The Nilsson TVT study One of the worst is a study by Nilsson, called the 17 year follow up. It used just 90 women but this dropped to 56 at the end of the 17 years and 12 of those were interviewed over the phone. Eleven women died. The oldest to be implanted was 87 when she had a TVT fitted. The average age is 54 and women would not have been so sexually active so the dyspareunia risk would not have been so obvious. The two leading trial authors were paid Ethicon consultants. Yet still this study is used to “prove” mesh is safe globally. It was used on the Oxford Hospital linkbut has been removed in 2018. Here on the Gynecare link 17 years follow up (2)
Another big problem is that the Randomised Controlled trials (RCTs) compare one type of mesh to another as oppose to mesh vs a natural tissue repair. This means results may well show a TVT sling is a better treatment option than a TVTO sling for incontinence but if more trials were done comparing plastic fix to a patient’s own tissue fix we would have a better selection of studies to deem if mesh genuinely was better than native tissue for being both a safe and effective treatment option.
There is currently a crisis of confidence in evidence base. There are 40,000 clinical trials – how do you find the useful unbiased ones? Ethics, regulation, research bodies and conflicts of interests are a concern across the entire medical device and pharmaceutical industry.
Another problem is poor auditing of problems experienced by women. For example in the Single Incision Mini Sling (SIMS) trials, the questionnaire shows that medics do not fully allow women to report their quality of life complications. Read the story here.
This article from 2009 by Robert Freeman shows that only 3% of 120,000 women given mesh are recorded anywhere so it is clear to see nobody is properly monitoring how the product is faring. He also says reviews are poor quality and do not provide meaningful results.
Anzjog Journal Transvaginal mesh let’s not repeat the mistakes of the past
Yeng, Raz et al Mesh risks are devastating and happen more frequently than appear in the literature
The MHRA and the NHS quote a figure of mesh risk as being as low as 1 to 3%,. To calculate that risk they have used figures for pain and erosion but not for dyspareunia. They say risk of dyspareunia (painful sex / lost sex life) is as high as 13.5%. The following research shows a range of very different figures. The reality, of course, is that nobody knows the true scale of the mesh disaster because there is poor auditing of outcomes and less than 40% of surgeons report to the main BSUG database. also they did not incude the risk of dyspareunia (loss of sex life) to help keep the figure low. In the York report the dyspareunia risk is shown as 14.3% (they wrongly put it at 13.5% but the fact remains, this risk was not included in their calculations; See page 4 of the York Report).

Mesh kits do not make ethical sense – 2009
Before the advent of mesh kits, there was little commercial interest in gynaecologic surgery aside from the sale of sutures or catheters, but now there are operation-specific kits, huge profits are on the table.

Mesh can shrink by 20 – 75%
Stanek et al talks about what can lead to complications. The paper reports that “Within a year of the procedure, a mesh positioned evenly underneath the urethra may shrink up to 20-30% after the implantation, whereas if it is wrongly positioned and folded, it may shrink up to 75% of its volume. The above mechanisms may lead to obstruction in the urine flow and consequently to the erosion of the urethra.”

Vaginal pain risk from mesh shrinking: prolapse and incontinence mesh
Donald Ostergard wrote in 2010 that scar tissue causes mesh contraction to less than 50% of the implanted size, which results in dyspareunia and tension on the pelvic mesh attachments. Such contraction may cause pelvic pain and subsequent erosion into adjacent organs. An individual response in fibrosis also exists, with some individuals being “high responders.”
Manufacturers need encouragement to develop meshes that are inert and incorporate without contraction along with routine clinical tests to detect “high responders” to avoid complications. Polypropylene is not inert within the human body.
Incontinence mesh risk is 12%
New study by Chapple et al in European Urology says complications are 12% which is one in eight women suffering.
Risk: incontinence mesh 30% to 40%
Surgeon Firouz Daneshgari from the Department of Urology, Case Western Reserve University, Cleveland, US says: “Almost two decades after the introduction of TVT and midurethral slings into clinical practice, and by any modern industrial standards of quality, a 30–40% rate of adverse events is simply unacceptable.
“Whether or not this is due to changes in names or mechanisms of action is not relevant.
“Can any of us imagine what would happen if one-third of all cars, computers, food packages, or any other commodity we purchase would fail or result in recalls?
“Moreover, it is unlikely that the manufacturer would remain in business after such recalls and failures.
“In either a single-institution case series or multi institution, we impose an adverse event on at least one third of our patients. In the Serati et al. report, up to 30 per cent of patients developed de novo urgency.
“Similarly, results of two of the largest RCTs involving midurethral slings revealed a nearly 42 per cent rate of side effects. One can attempt to tease out the differences in types of adverse events, but the big picture remains the same.”
The Serati et al study (30% de novo urgency) to says : “The 10-yr results of this study seem to demonstrate that TVT is a highly
effective option for the treatment of female SUI, recording a very high cure rate with low complications after a 10-yr follow-up.”
The Brubaker study (42% adverse events) to which Daneshgari refers..
Chang and Lee say it is only prolapse mesh that is a problem and “skewed” media reports are saying incontinence mesh aka mid urethral slings like TVT, TVTO and TOT are a risk. They also claim women are only making a fuss as they are attracted by “big pay outs”
Of women suffering problems 77% were severe
In the American Journal of Obstetrics and Gynaecology AJOG, a study by Abbot et al , shows 347 patients sought help for synthetic mesh-related complications.
30% had dyspareunia aka lost or reduced sex lives, 42.7% of the patients had mesh erosion and 34.6% had pelvic pain. It says 77% had a grade 3 or 4 (severe) complication.
Risk: incontinence mesh is 42%
A report headed by Linda BRUBAKER, 2012 shows adverse episodes occur for up to 42% of women following a mesh sling implant for incontinence.
It says 20% of those are serious. Yet the authors say mesh is still acceptable to use. How high must the complication rate be?
There are 11 authors and only five declare “No Conflict of Interest” The other six are all MDs except for Yan XU who has a Master’s degree.
Among the non-declared conflicts of interest (COI), Gary Lemack received $136 832 in 2013-2015. To check his COI visit this site. This paper claims pain beyond six weeks was 2.3% which seems unlikely.
This same TOMUS study is followed up after 5 years and miraculously the adverse events suddenly fall to 10% Smell a rat? We do! Also in this study the efficacy says it is only 51.3% which means a failure rate of 48.7%
Brubaker says 35% removal risk
Brubaker et al who was involved in the TOMUS study of 2012, said in 1997 that mesh removal risk was as high as 35%
Risk of prolapse mesh is 36%
Schimpf et al found erosion risk for prolapse mesh is 36% of women but said re-operation rates were low. It is abundantly clear from this study that researchers are only seeing that the initial prolapse problem has been fixed. They are not looking at problems for more than a third of patients. Erosion is where the mesh cuts into nerves, organs, tissues and causes exruciating lifelong pain.
Risk of prolapse mesh problems is 34%
Knoedler et al show one in five women need re operation after prolapse mesh. A total of 34% had mesh poking through/extruding through vaginal walls and 16% say they were very unsatisfied with the operation.
Risk of prolapse mesh cutting into tissue 15.6%
Iglesia et al This study showed erosion, a medical term for the mesh slicing into tissue, nerves, muscle, vaginal walls, is one in six women.
Risk of incontinence mesh is 27.6%
A report by Sue Ross1, Selphee Tang1, Misha Eliasziw, Doug Lier, Isabelle Girard1, Erin Brennand1, Lorel Dederer, Philip Jacobs, Magali Robert says the risks are nearly one in three women who suffer complications.
The report says 27.6% of women suffer complications following a TVT and 21.8% for a TOT..
Both versions are plastic mesh slings and both support the urethra but are just inserted differently.
Authors said: “Serious adverse events and tape effectiveness did not differ between groups at 5 years.” truth is all mesh has serious risk regardles of whether it is TVT, TVTO or TOT.

Risk of reduced or lost sex life is 26.5%
A table of studies to show loss or reduction of sexual function. The worst is by Mazouni et al. (2004) which says 26.5% have reduced sexual dysfunction – that is one in four women. A terribly high risk rate.
Risk of reduced or lost of sex life is 14.3%
Marszalek et al. 2007. said in this report: “Our investigations showed that the influence of the TVT procedure on female sexual function is evident, but of low impact, and in general will not be of relevance.”
Risk of Urinary Tract Infection is 22%
This review by Daniel Rapoport, Howard Fenster, and Jamie E. Wright quotes a figure of 22.3% risk of suffering painful UTIs after having TVT mesh and 19.7% risk of urinary retention.
It says: “The various tape procedures offer an innovative approach to the treatment of urinary stress incontinence and offer good clinical results in the hands of the well-trained, experienced surgeon.
Nonetheless, there are complications that have been noted in the literature and in our experience. Some complications can be very difficult to treat, such as post-op pelvic discomfort and voiding dysfunction, and patients should be aware of these complications prior to surgery.”
Mesh benefits do not outweigh risks
A study by Tom Margolis looks at Polypropylene mesh benefits do not outweigh the risks
Single incision mini tape study
Hilton et al. This study of 60 women between 2002 and 2006 shows this trial, done under local anaesthesia, resulted in 12 (20%) experienced mesh complications, half of which were considered to be serious adverse events requiring exit from the study. At 2 years following Minitape™ insertion, six women (10%) were defined as cured. This is a terrible complications and cure rate!
TVT Secur seven out of ten failure rate
Promises broken. In our experience, the TVT SECUR device definitely
did not stand the test of time, with a 31% success rate after a 4.5-yr of follow-up. It should not be considered a valuable option for SUI management unless supplementary data is provided regarding its long-term outcome. The lifecycle of the TVT Secur is here in this report. Removed from market in 2013.
This 2010 study in European Urology says failure is 42% over three years TVT Secur terrible results
However this 2009 TVT Secur study from the UK from a two year period from 2007 to 2009 says it is safe with low complication rates. TVT secur good results in UK – doesnt tally
Prolapse repair with mesh has a 47% risk of developing another prolapse
Pain risk 31% No long term follow ups.
A review by Ackerman and Raz says that most reports do not follow up women after the one year mark. Mesh complications can take months or years to cut in. This report reckons chronic pain risk could be as high as 31%.
Risk of bladder perforation up to 31%
Training surgeons to use mesh is difficult as they cannot see what they’re doing. It is a bit like touch typing. Or trying to fix a car’s fan belt without lifting the bonnet.
Hilton and Rose said: “Whilst seductively simple in concept, mid-urethral tape procedures are not without risk.
“Their inherently “blind” nature makes them difficult to teach. The “learning curve” to independent practice may be longer than previously considered.”
Biased medics and small trial numbers
Some of the authors/surgeons involved in producing studies have conflicts of interests which means they have received payments in kind from the medical device manufacturers.
An example is this study from May 2017. The author says there is no link between surgical mesh and autoimmune conditions like fibromylagia or cancer. Yet the surgeon’s work that he bases his conclusion on, has had industry payments. Here is the study and the link to his industry payments.
Or this example. Surgeon Vincent Lucente bragged in 2007 that he encouraged an American surgeon society to remove the word “experimental” from its literature about a new prolapse mesh kit by Ethicon because it would scare people off. At the time he was the highest paid trainer of other surgeons by Ethicon. He still has conflicts of interest today, click here to see how much. He still today speaks of how he has a passion for pelvic mesh surgery. At $318,485.63 it doesn’t take a genius to work out why.
Some have sponsorship or research grants. This means their reports are at risk of bias.
The Cochrane Review looked at 81 mesh trials and found only two were at low risk of bias. A total of 13 were high risk and in the other 66, bias was unclear. Read the story here.
Other trials use woefully low patient numbers making it difficult to capture a clear picture of risk
Hospital Episode Statistics (HES)
Some studies use HES which only give numbers of women admitted to hospital for their mesh problems. This ignores a whole army of patients suffering who never go into hospital because they are told their pain has nothing to do with their mesh implant.
Or they simply go back and forth to GPs for pain killers.. Their story is never captured in the HES data.
Don’t believe the hype
A report published in the Lancet gives the impression that it follows women for 18 years from 1997 to 2016 . It doesn’t. It only follows women for up to five years but takes statistics from an 18 year period.
The statistics used are called Hospital Episode Statistics HES. These figures are of women who go into hospital for a mesh complications so it doesn’t tell the story of women going to their GP for pain killers. Nor does it tell the story of women going for repeat antibiotics for urinary infections. HES data will be a vastly under reported set of figures for mesh complications.
A study in Denmark by Nilsson said it followed women for 17 years. It picked 90 women who had a mesh implant. Of those, only 70 women agreed to a final interview and most were done over the telephone at the end of the 17 year period. It claims one woman had a mesh exposure and no other complications occurred. Two of the medics involved in this study had financial interests with the mesh manufacturers. Yet Oxford Pelvic Floor Centre rely on this study to tell women that mesh is safe.
Synthetic slings not safe
Doctors A. Lenore Ackerman and Shlomo Raz say synthetic slings are not safe.
This review says mesh erosion (including exposure, extrusion and perforation) varies widely from 0–33%. The average incidence of graft erosion is 10.3%. Other studies say it is 0–7.3%. Yet another study shows it is 0–21% for POP surgeries. If nothing else this review – which looks at a range of literature already out there proves nobody knows the true scale of this disaster
This study says of mesh for Stress Urinary Incontinence SUI that: “current data suggest that the use of non autologous durable materials in surgery has well-established benefits but significant risks” but ends with the line, mesh has “acceptable morbidity.” Consensus Statement of the European Urology Association and the European Urogynaecological Association on the Use of Implanted Materials for Treating Pelvic Organ Prolapse and Stress Urinary Incontinence.
Mesh triggers autoimmune disease
We see hundreds of women in support groups globally suffering auto immune diseases like fibromyalgia and lichens schlerosis. This study was carried out in 2017 by Bilal Chughtai which says there is no link between mesh and auto immune conditions – yet interestingly Mr Chughtai received around $140,000 in payments in the year before this study was published.

Pitfalls of mesh
Although mesh insertion seems like an easy procedure, treating mesh complications involves complex procedures. Surgeons are not properly informing patients about mesh risk. Worse, complications are under-reported.. Even with complete mesh removal, more than 30 per cent of patients may be permanently disabled.
Polymers are toxic and plastic degrades
Osgtergard Degradation, effects of heat and infection of plastic. Risks were known before the giants starting marketing mesh slings.
Some reports recognise the plastic mesh material can cause problems
The Definitive User’s Guide and Databook by Clive Maier, Theresa Calafut shows that polymers are potentially toxic substances that should not be used in medical devices. See 10.4., 10.5 and 10.6. Beware of anything with the word poly in it as it may mean plastic.
Polypropylene plastic used to make mesh implants can leach toxins and break down under body heat once implanted. This study shows chemicals with unknown toxicity form when polypropylene plastic is heated – study by .Reingruber, E, M Himmelsbach, C Sauer and W Buchberger. 2010.
This study by Taylor from 2018 says polypropylene can suffer stress corosion failure which leads to mesh problems.
The plastic creates inflammatory response that continues years after implantation
AJOG In women with complications, mesh induces a proinflammatory response that persists years after implantation. Removed meshes show degradation; and pain is consistent with fibrosis
They knew the risks but sold it anyway
No long term follow ups
A review by Ackerman and Raz says that most reports due not follow up women after the one year mark. Mesh complications can take months or years to cut in. Study reckons complication of chronic pain could be as high as 31%.
EU upgrades mesh risk
Mesh to be upgraded to a higher risk medical device in the EU by 2020. See pages 469/70.
FDA says the implanting hooks are high risk
American watchdog body, the FDA, upgrades the trocars (hooks) to implant vaginal mesh implants, to a higher risk device.
PROSPECT study says a vaginal repair for prolapse with mesh or graft material did not improve women’s outcomes in terms of effectiveness, quality of life, adverse effects, or any other outcome in the short term, but more than one in ten women had a mesh complication.
The implantation of any mesh for the treatment of prolapse via the vaginal route should be only considered in complex cases in particular after failed primary repair.

Back to the future
Time honoured incontinence fixes like Burch colposuspension are making a come back as more women opt out of mesh sling operations. Social awareness of mesh sling complications play a part in this.
Mesh degrades under heat
Donald Ostergard “Many properties of polypropylene mesh that are causative in producing the complications that our patients are experiencing were published in the literature prior to the marketing of most currently used mesh configurations and mesh kits. ”
Surgical practice driven by commercial interest
Vaginal Support Device Study by Carey and Slack
Emerging problems with mesh:
K Baessler. Mesh is a good fix as in anatomical outcomes but pelvic floor symptoms are scarcely reported in reviewed trials, so how does anybody really know quality of life after a mesh implant?
Abbott Most women who seek management of synthetic mesh complications after POP or SUI surgery have severe complications that require surgical intervention. A significant proportion require more than one surgical procedure. 305 of them have lost sex lives and 42.7% had erosion.
Ethicon release brochure with risks of mesh but those risks are not included in UK patient information leaflets See P6. Risks of exposure, infection, pain, foreign body reaction, fistula, urinary tract obstruction
TVT Secur was not getting good results in the studies but Douglas Tincello, of Leicester, wanted to run a trial on it . Short-term 93.5% success..Long term only 40% patients cured & 42% failed. It was quietly taken off the market in 2012.
PeterAngelos To uphold professionalism, surgeons must be driven by altruistic motives rather than self-interest. They must not allow the lure of the new and potential for financial benefit to influence their assessment of whether an innovative procedure truly benefits the patient.”
What even is this device – the Vaginal Support Device used for 4 weeks to support Prosima mesh.
European Association of Urology Mesh slings in an era of uncertainy by Chapple, Raz, Brubaker and Zimmern. Beyond the current, passionate debates for or against synthetic material, there is limited knowledge about the long-term integration of these devices into the vaginal wall near vital adjacent organs and the risks and benefits of the devices’ added strength versus native tissue repair.
Serious irreversible complications

Kokanali et al Women’s pain and complications not taken seriously even in the studies! In this one it says mesh erosion following vaginal sling procedures is a frustrating complication with relatively low incidence.

Steep learning curve & while surgeon practices women are injured
Hilton & Rose It is a steep learning curve to teach how to insert mid urethral slings “Whilst seductively simple in concept, mid-urethral tape procedures are not without risk; their inherently “blind” nature makes them difficult to teach. The “learning curve” to independent practice may be longer than previously considered.”
Jason Cooper says mesh erosion is easy to fix – yet few surgeons can successfully remove the plastic implants once they’ve embedded into a woman’s pelvic tissue after 6 weeks. He also says as time goes on surgical skill will improve to implant these devices – yet they have been around 20 years and still srugical skill hasnt improved and all the time women are injured.
Rogowski et al found an ongoing reduction in the mesh size – they found it can shrink up to 53%.
Mesh erosion and pain with mesh vs native tissue
The true incidence of complications is not known, as less than 25% of patients return with their sling problems to the same surgeon. Under reporting is a major issue Lise Hanne Christensen, Herlev Hospital, University of Copenhagen and Thomas Bjarnsholt, of University of Copenhagen
Mesh erosion is anything from 0 to 33%
This study by Shah, Badlani et al gives widely varying figures for mesh erosion.
Surgeons dont see point of reporting problems
BMJ study – Gagliardi Urbach et al. Participants perceived Adverse Medical Device Event (ADME) reporting as unnecessary, not possible or futile. Physicians were not motivated to report AMDEs because they viewed them as an expected or unavoidable part of practice that they themselves could manage by switching to different devices or by developing work-around strategies to continue using problematic devices. Device industry factors (no feedback to reports of AMDEs, little impact on device improvement) and healthcare system capacity (lack of systems for AMDE reporting, lack of patient monitoring for AMDEs, poor patient record of devices used, purchasing contracts constrain device choice) reinforced individual physician views and behaviour. As a result, some physicians used devices that were less than ideal for a given patient or with which they were unfamiliar, potentially leading to poor patient outcomes.
No patient information leaflets for five years
Welsh women not given patient information leaflets for prolapse operations using mesh from 2006 to 2011. How is this fully informed consent?
NICE In 2014 a court ruling said that CCGs cannot refuse to give treatment or ignore NICE guidelines just because they don’t like them .
Linda Cardozo says in 2000 that slings need more randomised controlled trials and follow up for 5 years. In 2018 this is still not happening and most follow up is less than two years
In 2003 a Health Technology Assessment said long term efficacy and risks of TVT were not known HTA report. Further research suggestions include unbiased assessments of longer term performance from follow-up of controlled trials or population-based registries; more data from methodologically sound RCTs using standard outcome measures; a surveillance system to detect longer term complications, if any, associated with the use of tape; and rigorous evaluation before extending the use of TVT to women who are currently managed non-surgically NONE OF THIS WAS DONE

Patients are guinea pigs
BMJ Article by Mary Madden who asked the MHRA should they have stricter controls on medical devices? The MHRA said: “We think that requiring pharmaceutical-style clinical trials for medical devices would be disproportionate. There is a limit to what extent devices can be assessed pre-market. Unlike medicines, it is not feasible to accurately predict the likelihood or time to failure for new medical devices via pre-market studies. In practice, such studies of sufficient size and diversity are either impractical or so onerous that they would block the product’s development process.” Thus admitting patients are the human guinea pigs

Handley “unreasonable adverse attention”
This article talks of an unreasonable amount of adverse attention to the current gold standard for treating SUI, the mid urethral sling.
Treatments for SUI depends on surgeon opinion
No consensus exists among surgeons for recurrent SUI. However, many surgeons say they would put another mesh sling in if the first one fails!
Oxford audit shows a third of women need to self catheterise after TVT mesh tape
Audit by Natalia Price and Simon Jackson claims TVT is a good treatment option and used this as an audit so mesh was used routinely in hospitals circa 2003. But it shows on page 7 that a third of women, 27% , have to self catheterise afterwards. Also 57.9 % had this mesh as primary surgery while 41.6% had it for failed previous Sui surgery in this audit.
Mini Slings failed for nine out of ten women in Manchester

Gender bias in medicine
Carey et al This study from 2017 looks at a range of women’s medicines and devices, including mesh and says: “historical precedence has described a generation of morbidity and mortality associated with unrecognised sex- and gender-specific adverse events that continue to affect individuals today. Although significant advances have been made to recognise and prevent additional gender bias in future drug and device trials, continued scrutiny and vigilance should be practiced among manufacturers and researchers as novel sex- and gender-specific adverse events continue to occur.”
2011 How do British urogynaecologists deal with failed mid urethral slings? I think everyone needs to work out what “failed” means. Does it mean it is no longer fixing the problem or does it means it has failed because it is causing chronic pain, loss of sex life, chronic UTI?

8 out of 10 failed mesh slings – surgeons just put another mesh on top
This 2017 study says 78% of the UK surgeons surveyed just leave the old tape in place & put another on top if it fails.. Which is why UK removal rates aren’t an indication of the true complication rates for sling tapes..No wonder they are panicking.
TOP 5 QUOTES TO MAKE YOUR EYES ROLL:
1. This is “a consequence of training and experience rather than an actual preference. It appeared that many respondents were unable to offer alternative procedures because they had not received training in procedures such as Burch colposuspension or autolgoous sling.”
2. “This is an important finding not only for future research plans, but also as a training and clinical governance issue, bearing in mind the increasing concerns about Mid Urethral Tape complications, how they are managed, and the possibility of providing women with alternative choices.”
3. “From the patients’ perspective, the variability and inconsistency of surgeons’ responses in general is a finding that will generate considerable concern, particularly given that this survey was only sent to those with specific training and a declared interest in pelvic floor dysfunction.
4. “Patients hope and expect that doctors know what they are talking about and that treatments offered are the most suitable/effective. However, it is clear from the data that the treatments women may be offered may depend largely upon the discipline and training of the surgeon, and that the choice of treatments offered depends upon the surgeon’s skills, experience and opinion rather than any evidence.
5. “This highlights the importance of comprehensive and appropriate training, in addition to the need for research addressing the specific issue of failed continence surgery, to avoid and reduce the variability in patient choice that is currently present and to provide greater consistency of care provision.”
This article reckons mesh removal rates for mesh slings are 3.3% yet Keltie et al found risk of an overnight stay with a serious complication to be 9..8% then the Guardian working on HES data found it to be 6.5%. So who is correct?
JAMA study Mesh complications are more than just removal
Paper by Ipek Gurol-Urganci Dolan et al says mesh removal rate is 3.3% and 6.8% have some kind of re-operation within 9 years. At Sling The Mesh we say removals or re operations are only a small chapter in the story behind the mesh disaster. JAMA long term study of mesh
A survey in 2017 in STM shows 70% of women have not had mesh removals yet are suffering irreversible, life changing pain, infections and lost sex lives.
JAMA also shows that it doesn’t matter if surgeons implants large volumes of mesh or do not insert much – complications rates remain the same. See the tables in the link in pdf format here: JAMA long term study of mesh

This trial, led by Mark Slack and 2019 President of RCOG Eddie Morris, is based from Norfolk and Norwich hospital but is on hold during the suspension. The patient consent form has zero details on what women are signing up for and does not warn of risks. The trial focuses on efficacy of PVDF and compares erosion rates to Polypropylene. Look at the archive link.
The trial paperwork admits shrinkage is a problem with polypropylene mesh, so that is why they invented their new shiny Dynamesh.
“The sling being studied is DynaMesh®SIS soft, made of polyvinylidene fluoride (PVDF) which has improved biocompatibility with tissues, meaning reduced scar formation and less mesh shrinkage.”
It appears N Ireland held a pre trial of Dynamesh?

It’s Russian Roulette! Not Smoking hysterectomy and prolapse surgery
This paper from 2018 reckons smoking, hysterectomy and prolapse surgery puts women at higher risk of needing mesh revision surgery. Not true! Patient experience shows it is Russian Roulette risk. This commentary says more studies are needed to f ind out who is at risk but we say it is a waste of time as you cannot predict who will suffer.
Men’s mesh slings
Will this be the next scandal? The MASTER study looks at Artificial Urinary Sphincter cure rate of 82% vs male sling 63%. Why risk mesh problems at such a low cure rate? The trial’s ethics approval are terrible. It says there are no risks posed to patients. It only follows up for two years. The trial focuses on efficiency and cost effectiveness. Quality of life and sexual function is included , but will be looking at it in relation to the incontinence problems and questions are likely to be confusing for that reason. The male sling costs £6,000. NHS cost of £4,000 plus device cost of £2,000. The artificial urinary sphincter costs £9,000. NHS costs of £4,500 plus device cost £4,500.
GPs guide to mesh
- 2018 study: Mesh is supposedly low risk and successful outcomes It’s easier to show improvement , after mesh surgery if patients are inactive or low active sexually, before, so even 1 sexual episode after is 100% improvement. In this study 79 of 237 patients didn’t complete sexual function study = 2/3 of missing data!.
2. 2017 study: This Tissue Fixation System study only looks at long term success. It doesn’t look at long term pain or sexual dysfunction. Also it only cured 52% of women for SUI after 5 years and 79% of women with prolapse after 5yrs.
