Description
Summary:	Literature concerning corporotomy location in multicomponent inflatable penile prosthetic surgery via a penoscrotal approach is scarce if not nonexistent. Aim of our study was to report practices in low-, moderate-, and high-volume penile implant centers regarding corporotomy location and evaluate its potential impact on intraoperative and short-term postoperative complications. Data from 18 (13 European and 5 American) implant centers were collected retrospectively between September 1st, 2018 and August 31st, 2019. Variables included: intraoperative proximal and distal corpus cavernosum length measurement, total corporal length measurement, total penile implant cylinder length, and length of rear tip extenders. Eight hundred and nine virgin penile implant cases were included in the analysis. Mean age of participants was 61.5 ± 9.6 years old. In total, 299 AMS 700™ (Boston Scientific, USA) and 510 Coloplast Titan® (Minneapolis, MN USA) devices were implanted. The mean proximal/distal corporal measurement ratio during corporotomy was 0.93 ± 0.29 while no statistical difference was found among low-, moderate-, and high-volume penile implant centers. A statistically significant correlation between lower proximal/distal measurement ratio and higher age ( p = 0.0013), lower BMI ( p < 0.0001), lower use of rear tip extenders (RTE) ( p = 0.04), lower RTE length ( p < 0.0001), and absence of diabetes ( p = 0.0004) was reported. In a 3-month follow up period, 49 complications and 37 revision procedures were reported. This is the first study reporting the current practices regarding corporotomy location during IPP placement in a multicenter cohort, particularly when including such a high number of patients. Nevertheless, the retrospective design and the short follow up period limits the study outcomes. Corporotomy location during penoscrotal IPP implantation does not correlate with intraoperative or short-term postoperative complication rates. Future studies with longer follow up are needed in order to evaluate the association of corporotomy location with long-term complications.
