Reasons for and treatment of surgical complications with alloplastic slings.

Suburethral slings with tension-free vaginal tapes have become a popular treatment for stress urinary incontinence. Case reports on singleton complications are numerous and of clinical interest. Four European centers for urogynecology report on 328 surgical reinterventions after tension-free slings. Poor surgical technique is the most frequent cause of problems (45%), followed by incorrect indication (38%). The most frequent symptom is functional or anatomical outlet obstruction; perforation or penetration and defect healing are rare, but, apparently more frequent than described in studies or follow-up series previously.
