Incidence and predictive factors of orgasmic dysfunction after robot-assisted radical prostatectomy: A cross-sectional, questionnaire-based study

Objective We sought to evaluate the incidence and extent of orgasmic dysfunction in patients after robot-assisted radical prostatectomy and to identify factors that could predict patients at risk. Methods A single-center, questionnaire-based, cross-sectional study was conducted on patients who underwent robot-assisted radical prostatectomy (n = 523) between October 2010 and November 2019. In addition to six questions about sexual activity, orgasmic function, altered perception of orgasms, dysorgasmia, and climacturia, the International Consultation on Incontinence Questionnaire Short Form was administered. In February 2020, a letter was mailed inviting patients to participate in the survey. The primary outcome measure was the rate of orgasmic dysfunction. Logistic regression analyses were used to identify predictors of orgasmic dysfunction. Results Overall, 259 questionnaires were used for analysis. Among sexually active patients (n = 145), 33 (22.8%) reported anorgasmia, and 83 (57.2%) reported decreased orgasm intensity. Twenty-two (15.1%) patients reported dysorgasmia; among these patients, the pain was experienced almost always or always in 13.6%, sometimes in 13.6%, and a few times in 72.8% of cases. Climacturia was reported by 44 patients (30.3%). Nerve-sparing procedures decreased the risk of anorgasmia (odds ratio 0.37, 95% confidence interval 0.15-0.88) and urinary incontinence increased the risk of climacturia (odds ratio 3.13, 95% confidence interval 1.20-8.15). Conclusions These results indicate that orgasmic dysfunction after robot-assisted radical prostatectomy is relatively common.
