Women who require more surgery for complications after a mesh-based sling procedure have an increased risk of depression and self-harm behaviour, according to a new study by researchers at ICES.
Women with stress urinary incontinence leak urine when they cough, sneeze, laugh or are physically active. Mesh slings are made of synthetic polypropylene, a type of plastic, which are surgically implanted in the vaginal wall to treat urinary leakage. Mesh-based incontinence slings account for more than 90 per cent of incontinence procedures in women, and are associated with uncommon but potentially significant complications.
“There have been regulatory warnings and lawsuits related to significant transvaginal mesh complications. We wanted to quantify the serious psychological complications that can occur in women as a result of complications from transvaginal midurethral slings,” said Dr. Blayne Welk, senior author of the study and adjunct scientist at ICES Western, associate scientist at Lawson Health Research Institute and assistant professor at Western University’s Schulich School of Medicine & Dentistry.
To determine whether women who experience midurethral sling mesh complications requiring surgical intervention have an increased risk of depression or self-harm behaviour, Welk’s team tracked the number of Ontario women who needed a follow-up surgery to remove or fix a mesh implant and if they received treatment for depression or self-harm. The study, which was published online January 9, 2019 in the journal JAMA Surgery, included almost 60,000 women who had the procedure January 2004 through December 2015.
The researchers found that 1586 (2.8 per cent) underwent a surgical procedure for a mesh complication. Of those women, 11 per cent (175 women) were treated for depression compared to eight per cent of women (4,470) who didn’t have corrective surgery. Of the women who needed corrective surgery, 2.77 per cent of women suffered from self-harm behaviour compared to only 1.15 per cent of women who did not need corrective surgery. These risks were highest in younger women.
“Younger women are the ones who are most at risk of these mental health complications, and we suspect that’s because of a stronger negative association between the complications and intimacy among this age group,” says Dr. Welk.
The researchers add that when women experience midurethral sling complications, both they and their surgeons should be aware of the potential serious psychological impact of these complications.
ICES is an independent, non-profit research institute that uses population-based health information to produce knowledge on a broad range of health care issues. Our unbiased evidence provides measures of health system performance, a clearer understanding of the shifting health care needs of Ontarians, and a stimulus for discussion of practical solutions to optimize scarce resources. ICES knowledge is highly regarded in Canada and abroad, and is widely used by government, hospitals, planners, and practitioners to make decisions about care delivery and to develop policy. In October 2018, the institute formerly known as the Institute for Clinical Evaluative Sciences formally adopted the initialism ICES as its official name.
