Concurrent Penile Prosthesis and Artificial Urinary Sphincter versus Penile Prosthesis and Male Sling: A National Multi-Institutional Analysis of National Surgical Quality Improvement Program Database Comparing Postoperative Morbidity

Abstract

Purpose: We aimed to assess the 30-day morbidity in patients undergoing combined insertion of penile prosthesis (PP) and artificial urinary sphincter (AUS) vs. PP and male sling (MS). Materials and Methods: The National Surgical Quality Improvement Program database was queried to identify patients who underwent placement of AUS or MS combined with PP. Patient demographics, postoperative morbidity including complications, readmission and reoperation rates were recorded. Student t-test and chi-square or Fischer’s exact test were used as appropriate. Results: Forty-one patients met selection criteria between 2010 and 2016. Overall, 26 patients received PP and AUS vs. 15 that received PP and MS. Average age was similar in both groups (64.8±6.6 years vs. 62.3±6.3 years, p=0.254). Diabetes mellitus was more prevalent in PP+MS group compared to AUS+PP group (46.7% vs. 11.5%, p=0.022). Average length of stay was higher in PP+AUS group compared to PP+MS group (2.2±0.6 days vs. 1.8±0.4 days, p=0.017). Postoperative morbidity was reported in four patients in PP+AUS group. No reported complications in PP+MS group. In PP+AUS group, complications included one patient who developed urinary tract infection, one developed surgical site infection, readmission in two for postoperative infection, and one return to the operating room. No reported prosthesis explantation or revision in either groups. Conclusions: Our results showed that 30-day morbidity was recorded in the PP+AUS group and none in the PP+MS group. The complication and readmission rates remain comparable to the previous reports in both groups.
