title: Urinary continence after radical prostatectomy: predictive factors of recovery after 1 year of surgery.
abstract: OBJECTIVE
  To evaluate the clinical prognosis of incontinence and to determine the predictors for further recovery of urinary continence in patients not achieving urinary continence within 1 year after radical prostatectomy.
  
  
  METHODS
  A total of 708 patients were evaluated regarding urinary continence status at 1 year after surgery from a prospectively maintained radical prostatectomy database. Of these, 73 (10.3%) did not recover urinary continence within 1 year after surgery. For these patients, incontinence status and the number of pads for urinary control were assessed serially.
  
  
  RESULTS
  In 708 patients, factors associated with the recovery of urinary continence within 1 year after radical prostatectomy were membranous urethral length, prostatic apex shape and patient age. Among 73 patients with urinary incontinence, 41 (56.2%) achieved urinary continence with a mean time of 15.4 months subsequent to the first year after radical prostatectomy (baseline). A younger age at surgery (P = 0.027) and one pad being required (vs ≥2 pads) at baseline (P = 0.046) were identified as independent factors for achievement of urinary continence within a further 2 years. Only the number of pads was a significant factor for further recovery of urinary continence in the longer follow up (hazard ratio 0.36, P = 0.029).
  
  
  CONCLUSIONS
  Compared with factors related to the prostate or membranous urethra, patient age and severity of incontinence at 1 year after radical prostatectomy are more strongly related to the recovery of urinary continence later than 1 year after surgery. These findings might help to decide whether a definite treatment is required for persistent incontinence beyond 1 year after radical prostatectomy.
