OBJECTIVES: To characterize determinants of 4-, 12-, and 24-month urinary control after robot-assisted laparoscopic prostatectomy (RALP).
METHODS: Adjusted comparative study using prospectively collected, patient self-reported urinary control for 602 consecutive RALPs. Urinary control defined as: (1) EPIC urinary function (UF) scored from 0 to 100 and (2) continence (zero pads per day).
RESULTS: Both UF (62.8 vs. 42.4, P<0.001) and continence rates (47.2 vs. 26.7%, P=0.043) were better for bilateral nerve-sparing (BNS) vs. non-nerve-sparing (NNS) at 4 months, but only UF scores were significantly better at 12- (80.9 vs. 70.7, P=0.014) and 24-month (89.2 vs. 77.4, P=0.024) post-RALP. No difference in positive margin rates was observed. In multivariate analysis, older age (parameter estimate -0.42, 95% CI -0.80 to -0.04) and increasing gland volume (-0.13, CI -0.26 to -0.01) resulted in lower UF scores at 4 months, while higher pre-operative UF (0.25, CI 0.05-0.46), bladder neck-sparing technique (10.1, CI 3.79-16.35), BNS (19.1, CI 9.37-28.82), and unilateral nerve-sparing (19.00, CI 7.88-30.11) resulted in higher UF scores at 4 months. At 12 months, higher pre-operative UF (0.24, CI 0.083-0.40) and BNS (9.54, CI 1.92-17.16) resulted in higher UF scores. At 24 months, higher pre-operative UF (0.20, CI 0.06-0.33), bladder neck-sparing technique (7.80, CI 3.48-12.10), and BNS (7.86, CI 1.04-14.68) resulted in higher UF scores.
CONCLUSIONS: BNS, bladder neck-sparing technique, and higher pre-operative UF score result in improved 24-month urinary control after RALP.
