60-day degradation of polypropylene vaginal mesh raises safety concerns; NHS restricted use since 2018.

A University of Sheffield study found that vaginal mesh made from polypropylene degrades within 60 days post-implantation, raising concerns about its safety for treating pelvic organ prolapse and stress urinary incontinence. Polypropylene particles were detected in surrounding tissue, with concentrations increasing significantly over time. The NHS has restricted the use of these implants since 2018, prompting calls for safer alternatives from health advocates.
