HP-08-004 Factors involved in sexual function and sexual satisfaction in patients undergoing inflatable penile prosthesis implantation

Objective: Penile prosthesis implantation (PPI) represents the gold standard treatment for erectile dysfunction when conservative approaches (oral PDE-5 inhibitors, transurethral suppositories or prostaglandin injections) fail. Although many studies about PPI have been published so far, data about psychosexual dimensions and attitudes towards sexuality are lacking. The aim of this study was to analyse the factors involved in sexual function and sexual satisfaction in patients undergoing inflatable penile prosthesis implantation. Methods: We revised our institutional database of patients undergoing IPP implantation between January 2010 and June 2015. Exclusion criteria were: simultaneous urinary incontinence, simultaneous surgery for congenital or acquired recurvatum, previous urethral or penile surgery, removal of the prosthesis due to malfunction/infection. All patients were assessed pre- and postoperatively with detailed medical history, physical examination and scoring of sexual outcomes by validated questionnaires including the International Index of Erectile Function (IIEF), ISS (Index of Sexual Satisfaction) and Brief Sexual Attitudes Scale (BSAS) and a questionnaire designed at our referral center for penile surgery to ascertain time to and frequency of PPI use, and postoperative changes in penis size perception. Univariable and multivariable analyses were performed determine predictors of sexual outcomes. Results: Overall, 42 men met study criteria and were included in the analysis. Mean (SD) age was 62.3±7.1 (range 47-77). Among the several findings, the erectile function was the main predictor related to sexual satisfaction ISS total score (F(1,21)¼5.40; p<.05). Moreover, the highest number prosthesis activation, regardless of sexual activity, was positively correlated with a future higher frequency of sexual activity (r¼.69; p<.01). Conclusion: Several factors affect the resumption of sexual activity and the sexual satisfaction of patients after the prosthetic implant. This study revealed some interesting data for the pursuit of the best sexual outcome. Policy of full disclosure: Non
