Vaginal mesh slings for incontinence fail in about 3 percent


About one in 30 women who get a common type of vaginal surgery to address urinary incontinence will need repeat procedures within 10 years to remove or replace mesh slings inserted to prevent leaking urine, a study finds.
This risk is considered low, the authors note.
Patients fared best when they had slings inserted by surgeons who did the highest volume of these procedures. These patients were 37 percent less likely to need repeat procedures, the study found.
Women should make sure they know what their surgeon's past experience has been, lead researcher Dr. Blayne Welk of Western University in London, Ontario said in an email.
Millions of women develop urinary stress incontinence when muscles and tissues that support the bladder weaken. Simple actions such as coughing, running or lifting heavy objects can put pressure on the bladder and cause urine to leak. The risk increases with age, obesity, and multiple vaginal childbirths.
In the U.S., an estimated one in seven women will get surgery for urinary stress incontinence during their lifetime, Welk and colleagues note in JAMA Surgery.
While long-term follow up of some of the first women to get the slings found few complications after more than 17 years, some previous research has linked the devices to chronic pain, fistulas, and mesh erosions into the urethra or vagina, the researchers note.
Treatment of these complications can require repeat surgeries to remove or replace the devices, a possibility that regulators in the U.S. and Canada have highlighted in warnings to consumers and advised surgeons to explain to patients considering these procedures. In the U.S., more than 50,000 women have joined class action lawsuits related to complications with vaginal mesh.
Given the warnings, Welk and colleagues set out to examine reoperation rates and to assess how the surgeon's training and experience might influence the results. Overall, they looked at data on 59,887 women who had mesh slings implanted by nearly 1,000 different surgeons between 2002 and 2012.
After an average follow-up of five years, 1,307 women, or 2.2 percent, had needed a reoperation. However, when women were followed for 10 years, that rate rose to 3.3 percent.
