217 Maximization of Penile Length and Girth with Inflatable Penile Prosthesis Insertion: A Cadaver Study

Abstract

Penile length and girth after insertion of an inflatable penile prosthesis (IPP) are a concern for patients and surgeons alike. Stretched penile length (SPL) has been described as a good surrogate measure of erect penile length after prosthesis placement. In addition, several surgical techniques have been described to increase penile length during prosthetic surgery; however, these techniques have never been directly compared in terms of overall length increase. Utilizing cadaveric male pelves, we aimed to 1) determine the relationship between SPL and post implant length and 2) compare two techniques for penile lengthening. Ten previously frozen male cadaveric pelvises were obtained for a surgical training lab. Anatomic measurements were conducted from the pubis to the tip of the glans and at the midshaft of the penis to determine length and girth respectively. Inflatable penile prostheses were then inserted using a standard penscrotal incision under direct supervision by fellowship trained prosthetic urologists. The finger trap and the sliding technique penile lengthening procedures were performed as previously described in 5 cases each.
