“…Studies have also shown that papaverine has a signi cant inhibitory effect on venous out ow. 8,9 This property is exploited with preoperative injection to allow full dilation of the corporal bodies and increased tissue pliability. Given the dual mechanism of action on erectile function, papaverine can cause priapismic pain, and, as such, we co-administer with ropivacaine to minimize this side effect.…”

Three-piece inflatable penile prosthesis (IPP) is considered the gold standard surgical treatment for erectile dysfunction (ED). The most common cause of patient regret after penile prosthesis surgery is penile shortening. We sought to query a national database on average prosthesis length and describe our techniques to maximize cylinder sizes. We performed a retrospective review of the Coloplast database of 3-piece penile prosthesis cases performed over the span of 1 year nationally and by a single high volume surgeon and compared average cylinder lengths. Our review did not investigate whether adjunct tunical lengthening or girth enhancing procedures were performed. Between July 1, 2021 and June 27, 2022, 145 three piece penile prosthesis surgeries were performed at our institution. All were performed via a scrotal incision. Nationally, 32.8% were performed infrapubic while 58.1% were performed scrotal. The most prevalent cylinder length in our series was 22cm, compared to the most prevalent nationally of 20cm. Our technique to maximize cylinder length involves circumferential mobilization of the corporal bodies and corporal tissue sparing. Corporal tissue sparing is carried out by employing 9” Metzenbaum scissors rather than sequential dilators for corporal tunneling. The benefit of this approach is the ability to create a dorsal compartment to the level of the triangular ligament of the glans, thereby extending the space to the level of the midglans. This maneuver minimizes placement of the prosthesis anteriorly at the level of the fossa navicularis and prevents floppy glans that would otherwise compromise maximum cylinder length. Three piece penile prosthesis cylinder size can be maximized by circumferential mobilization of the corporal bodies, corporal sparing maneuvers, and the utilization of long Metzenbaum scissors for precise corporal tunneling.

Veno-occlusive dysfunction has become a recognized cause of organic impotence. The existence of concomitant arterial and sinus smooth-muscle disease makes this disorder often difficult to diagnose. It rarely can be the sole etiology for impotence. The authors’ experience in the treatment of this disorder in over 100 patients is presented. The authors rely on cavernosometry/pharma-cocavernosometry/pharmacocavernosography and the color duplex Doppler screening test (to eliminate concomitant arterial disease) as the primary diagnostic tools. Twenty-two patients of 58 (38%) have achieved long-lasting success from the surgery so that they are able to have vaginal intercourse. Another 12 patients (21 %) have been improved but must depend upon pharmacological injection therapy to obtain a sufficient erection for intercourse. There has been a 41% failure rate, and these are discussed.
