Abstract

Introduction
Given the penile fibro-vascular assembly was just thoroughly interpreted recently and inspired by impotent patients' questions during daily practice, so does the penile venous stripping (PVS), which is deemed controversial thus far. Despite primary impotence (PI) being ascribed to psychogenic origin, in the large repository of PVS treating PI, some 5 % remain refractory in the last decade, an analysis deemed required.

Objective
We sought to report penile crural dysplasia or hypoplasia that prevents sustainability compared to most PVS males thus far.

Methods
A retrospective analysis was conducted internationally on 45 consecutive young men with PI from 2013 to 2023. They were allocated into the crural dysplasia group (CDG, n=8), defined as a 50% diameter difference between the largest penile crus and corresponding corpus cavernosum or a 25% diameter difference of bilateral penile crura, and no crural-dysplasia group (NCG, n=37). On an ambulatory basis under acupuncture-aided local anesthesia, neither electrocautery nor a suction apparatus is used, with a circumferential or semi-circumcision followed by a pubic longitudinal approach, the PVS entailed the erection-related vein, including stripping a deep dorsal vein, two cavernosal veins after each emissary's vein was firmly ligated closest to the outer tunic layer with a 6–0 nylon suture. In contrast, the four para-arterial veins were only segmentally ligated. The overlying fascia layers and skin were approximated with a 6–0 nylon and 5–0 chromic suture for the skin, as did the semi-circumcision wound if it existed. The abridged 5-item version of the International Index of Erectile Function (IIEF-5) score system and the erection hardness scale (EHS) were used to assess erection restoration; preoperative data were based on masturbation; additionally, a radio-opacity index was used for comparison of the femoral cortex and that of penile crus preoperative and postoperative, respectively. Follow-up was primarily made via either INTERNET or telephone yearly. After this May, we introduced an autologous venous patch to augment the crural hypoplasia with a promising outcome on two new patients. Statistically, IBM SPSS 21.0 was used.

Results
The follow-up time was from 0.1 to 10.0 years, averaging 5.7 ± 1.1 years in the CDG and NCG groups, respectively. The blood loss is negligible. There is no difference between the operation time (4.9−0.8 hours vs. 4.8 ± 0.7 hours, p&gt; 0.88) for the CG and EG group, respectively. In both groups, there is a significant of IIEF-5 scores, EHS (5.7±2.0 vs. 15.9±2.1, 1.8±0.8 vs. 2.5±0.6; 5.8 ±2.1 vs. 22.4±1.1, 1.8±0.9 vs. 3.6±0.3; both P&lt;0.001) between the CDG and NCG. The preoperative radio-opacity of penile crura was unexceptionally enhanced postoperatively. In the NCG, 89.1% (33/37) are gratified; in contrast, 37.5% are satisfied in the CDG five years postoperatively, although surgery benefit is unexceptional reported. A close follow-up is going on with the two new males.

Conclusions
Penile crural hypoplasia is an unidentified contributor to primary impotence, although a larger sample size and longer-term follow-up are warranted.
