(018) CUFF CONUNDRUM: INFLATABLE PENILE PROTHESIS PLACEMENT IN MEN FOLLOWING TRANSCORPORAL ARTIFICIAL URINARY SPHINCTER

Abstract Introduction Concerns exist when inflatable penile prosthesis (IPP) surgery is performed following transcorporal artificial urinary sphincter (TC-AUS) due to risk of damaging the AUS cuff during proximal corporal dilation and device placement. Aside from rare case reports, no data exists on outcomes and complications in patients who undergo IPP surgery with existing TC-AUS in place. Objective We aim to describe perioperative complications, infections, revision rates, and device longevity when IPP surgery is performed with existing TC-AUS in place. Methods A retrospective search was conducted to identify all patients who had undergone TC-AUS placement at a single institution from 2015-2023. Patients who had undergone IPP placement following TC-AUS at the same institution were identified. Operative technique for IPP placement was similar to standard IPP surgery with additional care taken to avoid the AUS device and preferential use of electrocautery over sharp dissection. Operatives notes and all patient encounters were reviewed, and data on demographics, operative details, perioperative complications, infections, revision rates, and device longevity were recorded. Results 727 patients underwent TC-AUS placement from 2015-2023. Of these, 13 patients underwent subsequent IPP placement (fig. 1). All patients had history of prostatectomy, and 6 (46%) patients had prior radiation. The median follow-up after IPP was 31.7 months and the time gap between AUS and IPP averaged 18.3 months (range 2.3 to 56.7 months). Average operative time for IPP was 85 minutes (range 53 to 202 minutes). Reservoirs were all placed contralateral to the AUS reservoir to minimize risk of injury to the AUS device. 8 patients had a 12 Fr catheter left post-operatively for less than 24 hours. Proximal dilation was noted to be difficult in 2 patients (15%), both of which were successfully dilated without perforation or damage to the AUS cuff. No infections or erosions occurred. 3 patients (23%) developed mechanical failure at a mean time of 28.7 months following IPP placement (36.5 months after AUS). Cuff leak was identified in 2 patients and the third has yet to undergo revision surgery to determine etiology. Conclusions IPP placement appears safe and effective in men who have previously undergone TC-AUS without increased risk of infection or device erosion. Care should be taken when dilating proximally, though proximal dilation was uneventful in most patients. Mechanical failure rates may be slightly higher compared to patients who have either device alone, and patients should be counseled accordingly. Disclosure No.
