(403) Artificial Urinary Sphincter Implantation for Severe Post-Prostatectomy Incontinence in Setting of Salvage Radiotherapy and Prior Inflatable Penile Prosthesis

Abstract

Abstract Introduction Artificial urinary sphincter (AUS) implantation is one of the most common treatment options for individuals with severe stress urinary incontinence (SUI), which is a common complication after radical prostatectomy (RP). The modern AUS consists of a urethral cuff, pump, and reservoir, which serves as a replacement for the native incompetent sphincter. There are various surgical approaches for AUS insertion, including transperineal, transscrotal, and abdominal approaches. Objective This video covers the surgical technique for the implantation of an AUS for management of SUI. Notably, this patient underwent RP followed by salvage radiotherapy (XRT) for biochemical recurrence of prostate cancer and had prior inflatable penile prosthesis (IPP) placement. Methods A standard step-by-step surgical technique for placement of an AUS through a perineal incision and additional counter incision to allow for high submuscular placement of the pressure-regulating balloon is demonstrated in this unique case of a patient with prior IPP placement and salvage XRT. Results We highlight a meticulous dissection around the urethra in a case that had a challenging urethral dissection secondary to prior radiotherapy and a prior IPP in the proximal corpora. The AUS pump was successfully placed in the subdartos pouch of the scrotum on the contralateral side to avoid the patient’s prior IPP pump. At the conclusion, a flexible cystourethroscopy showed adequate AUS cuff coaptation and cycling. Conclusions This video covers the step-by-step technique for insertion of an AUS with a transperineal approach in the unique context of a patient with prior IPP placement and XRT. Preoperative counseling, evaluation, and careful intraoperative dissection of key parts of the procedure are critical for successful placement of the AUS, especially in patients who are at high-risk for complications, such as in this case.
