Sling incision with associated vaginal wall interposition for obstructed voiding secondary to suburethral sling procedure.

Obstructed voiding is a well recognized complication following a suburethral sling procedure. Current methods of transvaginal and transabdominal urethrolysis have had variable success rates in relieving the obstruction, and do not restabilize the urethra to prevent potential postoperative stress incontinence. We report on a procedure used in 4 cases which addresses both of these issues. All patients had persistent urinary retention beyond 8 weeks after a suburethral sling procedure. An oupatient procedure consisting of sling incision and associated tissue interposition (vaginal wall in three cases and fascia lata in one) was successful in relieving the obstruction. Continence status was maintained in 3 of the 4 patients. There were no major complications of this outpatient procedure.
