Improvement of severe baseline lower urinary tract symptoms following robotic-assisted laparoscopic prostatectomy.

Abstract

This study was designed to assess lower urinary tract symptoms (LUTS) following robotic-assisted laparoscopic prostatectomy. In a single surgeon series, 938 patients underwent robotic prostatectomy and completed International Prostate Symptom Score surveys at baseline and 6-month follow-up. Patients preoperative LUTS were categorized as mild, moderate, or severe according to the original International Prostate Symptom Score validation. Patient demographics, in addition to clinical and pathologic outcomes were obtained from an Institutional Review Board-approved database. Preoperatively, 55.8% of patients presented with mild, 36.4% with moderate, and 7.8% with severe LUTS. Increased prostate size trended with increased LUTS severity (P < 0.001). Patients who had severe preoperative LUTS witnessed a 57% reduction in International Prostate Symptom Score (from 24.1 to 10.7, P < 0.001). Men with moderate preoperative LUTS also witnessed a significant decrease in postoperative LUTS (from 12.1 to 8.3, P < 0.001). The majority of patients with moderate or severe LUTS improved significantly following robotic prostatectomy, with the largest improvements seen in the severe group. Prostate cancer patients with severe LUTS should be counseled on the beneficial role of robotic prostatectomy in an effort to improve their voiding dysfunction and as a viable cancer treatment.
