© 2018 AEU Introduction and aims: Urinary incontinence is a common complication after radical prostatectomy. The aim of our study was to describe the preoperative anatomical features using magnetic resonance imaging in order to predict early continence recovery after robotic radical prostatectomy. Material and methods: 72 patients who underwent robotic radical prostatectomy were prospectively analysed. EPIC questionnaire (1, 6 and 12 mo) and first self-reported continence were used to assess functional outcomes. Membranous urethral length (MUL) and MUL-prostate axis angle (aMULP) were assessed preoperatively on T2 weighted sagittal images. Results: Continence rate was 67.2%, 92.6% and 95.2% at 1, 6 and 12 months, respectively. Early continence was achieved in patients with the lower aMULP. At 1 month, average aMULP in continent patients was 107.21° (IC 95% 90.3-124.6) vs. 118.5° (IC 95% 117.7-134) in incontinent ones (P=.014). At 6 month differences in aMULP among groups were found: 114.24° (IC 95% 104.6-123.9) in continents vs. 142° (IC 95% 126.5-157.6) in incontinents (P=0.015). At 12 month, continent group showed a significantly higher preoperative aMULP. aMULP was revealed as the only independent predictor of urinary continence at 6 mo in multivariate analysis, OR 0.007 (IC 95% 0.002-0.012), P=0.012. Conclusions: Preoperative anatomical parameters assessment prior surgery can help to identified those patients will achieve early continence recovery and it supports therapeutic decisions making.
