The aim of this study was to describe the technical aspects and short-term outcomes of inflatable penile prosthesis (IPP) implantation after neophallus reconstruction at a single institution. Nine men with previously constructed radial forearm neophalli underwent IPP implantation. The etiologies of their penile anomaly were bladder exstrophy complex in five, disorder of sexual differentiation in two and genital obliteration secondary to ballistic trauma in two. Median follow-up was 9.6 months (range 1.5-139.7). The records for these patients were retrospectively reviewed and outcomes recorded. Mean age was 23.6 (range 18-31) years, and mean time interval from neophalloplasty to IPP implantation was 22.1 months (range 3-48). In all cases, 3-piece IPPs were employed, with eight of patients having one cylinder implanted in the native corporal body and extending into the neophallus. Mean surgical time was 222 min (range 142-409). Median length of implanted device was 22 cm. No intraoperative complications were observed. At the most recent follow-up, six patients (66.7%) had functional devices, with acceptable surgical outcomes. Three patients (33.3%) sustained device infections, and three (33.3%) sustained cylinder erosion. In three patients in whom neo-tunica albuginea were fashioned by ensheathing the cylinder with allograft human dermal tissue matrix, no erosions occurred. One patient underwent two revisions, the first for the associated erosion and infection and the second for genital pain, and was left with a semi-rigid prosthesis. IPP implantation affords the best opportunity for functionality for patients with a radial forearm free flap neophallus. Caution must be taken to ensure viability of the neophallus intraoperatively, and protocols to minimize the risk of infection should be followed. Fashioning neo-tunica albuginea using graft material may reduce risk of erosion.
