Abstract: | OBJECTIVE: To describe a technique of externally bulking the urethra with a soft-tissue graft before placing another artificial urinary sphincter (AUS), as when placing another AUS for recurrent male stress urinary incontinence (SUI) other manoeuvres, e.g. placing a tandem cuff or transcorporal cuff, must be used to obtain urinary continence in an atrophic urethra, and each is associated with morbidity. PATIENTS AND METHODS: From January 2003 to July 2004, five patients (mean age 74 years, range 62-84) treated by radical prostatectomy were referred for recurrent SUI after placing an AUS (four, including one with urethral erosion) or a male sling (one, with a resulting atrophic urethra). Each patient was treated with an external urethral bulking agent (Surgisis) ES, Cook Urological, Spencer, Indiana) and had an AUS placed. RESULTS: In each patient the greatest urethral circumference was <4 cm. To place a functional 4 cm cuff, the diameter of the urethra was enhanced by wrapping it with Surgisis ES. Continence was significantly improved in all patients except one 84-year-old man who had the replanted artificial sphincter removed because of erosion 14 months after surgery. CONCLUSION: In cases of severe recurrent SUI from urethral atrophy after placing an AUS, externally bulking the urethra with Surgisis ES before placing another AUS is well tolerated, and gives satisfactory results. |
