ABSTRACT
Few studies have looked at erectile function recovery (EFR) rates in men undergoing non-nerve sparing resection during radical prostatectomy (RP). Existing studies show great variation in EFR rates owing to multiple factors that minimize their utility in counselling RP patients. We investigated the EFR rate and its predictors in unilateral cavernous nerve resection and bilateral cavernous nerve resection patients 24 months after RP. We conducted a population-based, prospective cohort study of 966 patients who underwent RP at a tertiary cancer centre from 2008 to 2012. Cavernous nerve condition was evaluated on a 4-point nerve sparing score and assigned to one of three groups bilateral sparing, unilateral resection (UNR) and bilateral nerve resection (BNR). EF was assessed pre-RP and 24-30 months post-op using a validated 5-point patient-reported scale (1 = fully rigid; 5 = no tumescence). EFR was defined as a post-op EF grade of 1-2. Statistical analysis included descriptive statistics, anova, chi-square, Fisher's exact test and logistic regression. Mean baseline EF was 1.84 ± 1.3 and 2.74 ± 1.5 for UNR and BNR patients respectively. Thirty-three percent of UNR patients and 13% of BNR patients exhibited EFR. Age, baseline EF were predictors of EFR. Multivariable analysis showed baseline EF was a significant predictor of EFR at 24 months for UNR. For BNR patients, pre-RP EF was the only factor predictive of EFR. Patients undergoing nerve resection still have a significant chance of achieving true EFR, with UNR surgery patients showing more potential for improvement than patients undergoing BNR surgery. Age and baseline EFR characterize recovery prospects in these two groups. Physicians should thus measure and account for baseline EF in addition to age and the degree of nerve resection when advising patients about expectations for successful EF following RP.
