Preoperative evaluation of voiding patterns and detailed urodynamic evaluation before radical retropubic prostatectomy was carried out in an attempt to tively. Ninety-two men, mean age 64 years (range 54-72), who completed 1identify patients at higher risk of developing urinary incontinence postopera-year of follow-up after radical retropubic prostatectomy for clinically localized adenocarcinoma of the prostate were included in the study. According to the preoperative urodynamic findings, patients were divided into two main groups: group 1 (n = 64) patients with normal urodynamic findings, and group 2 (n = 28) patients with abnormal urodynamic findings. The latter group was further subdivided according to the abnormality: detrusor instability (n = 12), weak sphincter mechanism (n = 9), and detrusor and sphincter instability (n = 7). The degree and incidence of urinary incontinence were evaluated in both groups at the 1-year follow-up visit. There was a substantial difference in the incidence of urinary incontinence between the two main groups with only 2 patients with incontinence in group 1 (3%) versus 11 patients in group 2 (39%). In addition, the incidence of incontinence in group 2 differed depending on the type of abnormality: the lower incidence occurred in patients with detrusor instability (17%) and the higher incidence in patients with both detrusor and sphincter instability (71%). Identification of sphincteric and bladder dysfunction preoperatively may indicate a high risk of urinary incontinence after radical prostatectomy.
