Suprameatal urethrolysis with Martius flap for refractory bladder outflow obstruction following stress incontinence surgery in females

AIMS To present our technique of suprameatal urethrolysis with Martius flap (SMUM) and outcomes of this procedure for refractory female bladder outflow obstruction (BOO). METHODS A retrospective chart review was performed to identify female patients who underwent SMUM between January 2010 and August 2016 after failed transvaginal urethrolysis (TVU) for BOO due to prior stress urinary incontinence (SUI) surgery. The primary outcome measure was surgical success defined as patient ability to void volitionally without need for catheterization or additional surgery for BOO. Secondary outcomes assessed included perioperative outcomes, intraoperative and 30-day complications, change in post-void residual volume (PVR), resolution of urge urinary incontinence (UUI), incidence of recurrent SUI, and treatment for any urinary incontinence. RESULTS Eleven patients were identified. After a median follow-up of 10.8 months (range 3.1-20.1), the procedure was successful in nine patients (82%). Postoperative median PVR was 29 cc (range 0-425) and median change in PVR was a 280 cc (range 29-1050) decrease (P
