title: [Assessment and prevalence of urinary incontinence after radical prostatectomy: Analysis of a historical series].
abstract: Prostate cancer can be treated by radical prostatectomy and provoke urinary incontinence as secondary effect. Our aim is to calculate the prevalence of urinary incontinence, characteristics of leakage and influential factors, through a historical series.
  
  
  
  We perform a descriptive, observational and retrospective study of 1310 patients who received treatment for PCa between 1989 and 2011. Prevalence was obtained after 12 months of recovery and using ICS definition. To complete ICIQ-SF and number of pads/day used we perform a cross-sectional study. The series is studied globally and divided in two groups according to oncologic characteristics. We perform a descriptive, comparative and predictive analysis.
  
  
  
  Prevalence of the series was 23.5%, 296 patients. 279 incontinent patients completed ICIQ-SF with a mean score of 11.1±4.03. 16.4% of the patients use 1 pad/day or none, 69% (11.4% of the total) use compress and 22% diapers. 8% of the total use more than 1 pad/day. Clinico-pathological factors divide series in two groups: 1989-1999 with a prevalence of 24.6% and 2000-2011 with 22.8%. Multivariate analysis shows influential factors: age (65 years) (OR:1.65, p=0.013) and prostate volume (50cc) (OR:1.49, p=0.029).
  
  
  
  Urinary incontinence is a disease with some prevalence that varies depending on definition. The most common situation was to leak several times a day (42.2%), a small amount (59.1%), using compress (69%) most of incontinents with a mild (0-7: 88.2%) impact on quality of life. Predictive factors were age (65 years) and prostate volume (50cc). The historical changes does not influence over prevalence.
