Urinary and Sexual Quality of Life 1 Year Following Robotic Assisted Laparoscopic Radical Prostatectomy

Abstract

We evaluated urinary and sexual quality of life 1 year following robotic laparoscopic radical prostatectomy and identified preoperative variables predictive of a severe decrease from baseline. Using a prospective robotic laparoscopic radical prostatectomy database we identified patients with greater than 1 year of postoperative followup. The UCLA-PCI SF-36v2 questionnaire was used to evaluate urinary and sexual quality of life before and 1 year after surgery. Severe worsening of the postoperative score was defined as a greater than 1 SD decrease. Demographic and preoperative clinical variables were evaluated along with baseline scores on univariate and multivariate analysis. Between February 2003 and September 2007 a total of 1,225 robotic laparoscopic radical prostatectomies were performed at our center and 361 patients (52%) met inclusion criteria. On multivariate analysis baseline urinary function was the only predictor of significant worsening of urinary function (OR 1.04, p = 0.003). Baseline urinary bother was the only predictor of significant worsening of urinary bother (OR 1.05, p <0.0001). A significant decrease in sexual function was predicted by baseline sexual function (OR 1.03, p = 0.0001), baseline sexual bother (OR 1.03, p = 0.005) and nerve sparing technique (OR 0.31, p = 0.05). Predictors of a significant decrease in sexual bother were also baseline sexual function (OR 1.02, p = 0.0001), baseline sexual bother (OR 1.04, p = 0.0007) and nerve sparing technique (OR 0.38, p = 0.02). ORs indicated that higher baseline scores corresponded to a higher risk of postoperative score worsening. We found that overall better baseline sexual and urinary scores are associated with better postoperative outcomes. However, the risk of a significant decrease in urinary function, urinary bother, sexual function and sexual bother is higher in patients with better baseline scores. Nerve sparing positively affects sexual function and sexual bother.
