title: Postoperative urinary incontinence exacerbates nocturia-specific quality of life after robot-assisted radical prostatectomy.
abstract: To elucidate the effect of postoperative urinary incontinence on nocturia-related quality of life after robot-assisted radical prostatectomy.
  
  
  
  A total of 100 consecutive patients who underwent robot-assisted radical prostatectomy completed a nocturia quality of life questionnaire score and a frequency-volume chart before and after surgery. These patients were divided into two groups by continence status (continent and incontinent) according to the number of pad exchanges per day and the 1-h pad test after surgery. Assessment was carried out before surgery, and then at 3 and 12 months after surgery.
  
  
  
  The Nocturia Quality of Life questionnaire total score and the Bother/Concern subscore were significantly lower in incontinent patients at 3 and 12 months after surgery (Nocturia Quality of Life questionnaire total score: Bother/Concern subscores P = 0.006: P = 0.04 at 3 months after surgery; and P = 0.04: P = 0.02 at 12 months). Both nocturnal maximum voided volume and nocturnal frequency were not significantly different between continent and incontinent patients. On multivariate analysis, nocturnal urinary frequency (P = 0.01) and urinary incontinence (P = 0.005) were significantly associated with nocturia-specific quality of life.
  
  
  
  Although the number of nocturia episodes was not significantly different between the continent and incontinent patients after surgery, the Nocturia Quality of Life questionnaire score was significantly worse in incontinent patients. In these patients, other than the number of nocturia episodes, psychological stress might worsen the Nocturia Quality of Life questionnaire score. Therefore, prevention of post-prostatectomy incontinence might be important to avoid aggravating the Nocturia Quality of Life questionnaire score.
