• INTRODUCTION:

  Artificial urinary sphincters (AUS) are used to treat significant urinary incontinence. Flexible cystoscopy at the time of AUS placement provides relevant intraoperative feedback including confirmation that the AUS is functioning, visualization of coaptation, and evaluation for urethral injury. Current guidelines for placement of an AUS do not include flexible cystoscopy. The objective was to evaluate whether flexible cystoscopy at time of AUS placement changed cuff size at the time of surgery.

  MATERIALS AND METHODS:

  A retrospective cohort study was performed to evaluate all patients undergoing AUS placement by a single surgeon between March 2013 and March 2017. The primary endpoint of the study was change in cuff size based on cystoscopy.

  RESULTS:

  A total of 109 AUS were placed in 96 patients. In five (4.6%) cases flexible cystoscopy identified a lack of coaptation of the urethra despite appropriate sizing which resulted in down-sizing of the cuff. Five patients were identified as having a bladder neck contracture that was previously unrecognized as clinic cystoscopy was performed by the referring urologist and was reportedly normal. Three patients developed postoperative infections, two of these patients had a history of multiple AUS placement and revisions and the third patient had a history of cystectomy and neobladder.

  CONCLUSIONS:

  Flexible cystoscopy at time of AUS placement changed the cuff size in nearly 5% of cases. Flexible cystoscopy at time of AUS placement provides valuable feedback and should be recommended for low volume prosthetic surgeons.
