Proximal corporal deformities may account for failed inflatable penile prosthesis (IPP) surgery. No contemporary series has focused solely on describing the natural history and management of isolated proximal corporal deformities in patients after IPP surgery. The aim of the current report is to present the clinical courses and surgical management with outcomes of proximal corporal deformities in the context of prior IPP implantation surgery. We conducted a retrospective analysis of the Johns Hopkins Hospital institutional database of IPP surgeries from May 2006 to March 2017 consisted of 198 patients who had undergone IPP revisions. All cases involving surgical revisions associated with isolated proximal corporal deformities (proximally from the penoscrotal junction) were identified. Data retrieved included clinical characteristics, operative findings, and surgical outcomes. Main outcome measures are the ability to achieve successful sexual intercourse after IPP revision. The findings of proximal corporal deformities were manifest in fifteen patients who had undergone previous IPP surgery. Deformities consisted of corporal dilatation (15 patients) and corporal rupture (8 patients). Associated prosthesis defects were mechanical failure (2 patients), aneurysmal dilatation (5 patients), and device breakage (4 patients). Median IPP treatment duration was 14 years. Mean number of prior IPP surgeries were 4.2 times. All patients underwent reduction corporoplasty with IPP device replacements consisting of controlled expansion devices. Mean age at revision was 59.7 years. All patients reported successful sexual intercourse and satisfaction within 6 months' follow-up after surgical revision. Proximal corporal deformities arising after IPP surgery are associated with dysfunctional device operation and as well as device defects. Proper recognition of this problem allows the opportunity for surgical correction with a definitive reduction corporoplasty. Failure to recognize these abnormalities timely may predispose to unsuccessful revisions and complicate future definitive surgical repair.
