We report the natural history of voiding function in men with clinically localized prostate cancer after robot-assisted laparoscopic radical prostatectomy (RLRP), describing the trend of functional recovery, which is currently not well described using the robot-assisted laparoscopic approach.

We determined the impact on voiding function by prospectively evaluating 100 consecutive men who underwent RLRP between May 2005 and December 2006 and compared their reported International Prostate Symptom Score (IPSS) and Quality of Life (QOL) scores at 3, 6, and 12 months with preoperative scores after surgery. Patients with preoperative IPSS of 0-7 and 8-35 were defined as having mild lower urinary tract symptoms (LUTS) and moderate to severe LUTS, respectively.

Continence was achieved in 82%, 87%, and 91% of men at 3, 6, and 12 months after RLRP, respectively. There were statistically and clinically significant improvements in both IPSS and QOL preoperative scores at all studied time points for patients with moderate to severe preexisting LUTS. The mean IPSS scores for these patients preoperatively and at 3, 6, and 12 months after surgery were 14.1, 5.2, 3.0, and 2.9, respectively and the corresponding mean QOL scores were 3.4, 2.1, 1.6, and 1.6, respectively. Patients with mild preexisting LUTS showed no statistically significant improvement in IPSS at 3 and 6 months after surgery but significant improvement was found at 1 year (P = 0.04).

Good continence recovery is expected in most patients undergoing RLRP. Patients with moderate to severe preexisting LUTS can expect early and clinically significant symptom and QOL improvements after RLRP. Patients with mild preexisting LUTS show significant symptom improvement at 1 year.
