(228) Would the Cylinders Lenght be Shorter in Men with Erectile Dysfunction After Prostatectomy or Peyronie's disease?

Abstract

Abstract Introduction Inflatable penile prosthesis (IPP) is indicated to treatment for Erectile Dysfunction (ED). The men with erectile dysfunction, after prostatectomy and/or peyronie’s disease can affect penile atrophy. The three-volume IPP consists of a reservoir, pump, and cylinders. Penile atrophy could increase the difficulty of cylinders insertion or space. Would the cylinders length be shorter in men with erectile dysfunction after prostatectomy or Peyronie's disease? Objective We aimed to compare the cylinders length of IPP in three groups: patients with erectile dysfunction after prostatectomy, ED with Peyronie's disease AND ED only. Methods Retrospective study, single-center, included men with erectile dysfunction submitted to inflatable penile prosthesis. Divided into group 1 ED after prostatectomy, group 2 ED with Peyronie's and group 3 ED only. We performed a Kruskal-Wallis test to determine whether there were significant differences between three independent groups. To determine which groups have significant differences, we performed multiple comparisons using Dunn's test with Bonferroni correction for p-values. Results 136 patients were included in this analysis, Group 1 ED after prostatectomy (n=25), Group 2 ED with Peyronie's (n=29) and group 3 ED only (n=82). Age of patients were 64,08, 52,65 and 54,11, respectively. The minimum cylinders length used was 17.5cm and the maximum was 26cm. The Kruskal-Wallis test result was significant (p < 0.001), indicating that at least one is different from the others. Dunn's test results showed that the group 3 has a significantly higher median than the 1 and 2 groups (p < 0.001), while there was no significant difference between the groups 1 and 2 (p = 0.891). Conclusions Men with erectile dysfunction after prostatectomy and men with Peyronie's disease have a shorter total cylinder length when comparing erectile dysfunction only. These findings are important to guide patients regarding the expected results in the postoperative. Disclosure No.
