Patient reported incontinence after radical prostatectomy is more common than expected and not associated with the nerve sparing technique: results from the Center for Prostate Disease Research (CPDR) database.
AIMS: The reported incidence of urinary incontinence (UI) after radical prostatectomy (RP) ranges from 2.5 to 87%. We reviewed data from the Center for Prostate Disease Research (CPDR) to determine the incidence of patient reported UI after RP (postRPUI) and establish risk factors for postRPUI. METHODS: We obtained IRB approval to query the CPDR database on all patients undergoing RP between 1990 and 2007. We assessed patient age, nerve sparing status, blood loss, margin status, stage, and patient self-reported incontinence status as entered into the database. Patients were counted as having UI only if the database showed patient reported UI in every follow-up encounter. Patients were counted as permanently dry if at any time in the follow-up they answered that they had no UI. RESULTS: Four thousand three hundred seventy four patients underwent RP without radiation therapy or hormonal ablation between 1990 and 2007. Complete data were available for 1,616 (37%) and 1,459 (90.3%) reported UI more than 1 year after RP with a median follow-up of 50.7 months. Older age is an independent risk factor for UI (OR = 1.021, P ≤ 0.0003). Nerve sparing, blood loss, stage of cancer, and margin status were not predictive for UI. CONCLUSIONS: Our data indicate that patient reported post-RPUI is higher than expected but is not related to the nerve sparing technique, stage of cancer nor blood loss at the time of surgery.
