Analysis of risk factors for urinary incontinence after radical prostatectomy
Abstract
INTRODUCTION: Our aim was to identify the independent risk factors associated with urinary incontinence after radical retropubic prostatectomy (RRP).
MATERIALS AND METHODS: Using univariate and multivariate analyses, we examined several pre- and perioperative factors. One hundred and sixty-six patients were divided into three groups: patients who were immediately continent after catheter removal (group I), patients who became continent later (group II) and incontinent patients (group III).
RESULTS: There were 34 patients (20.5%) in group I, 111 (66.9%) in group II, and 21 (12.6%) in group III. The multivariate analysis between the continent and incontinent patients proved that the postoperatively measured total length of the posterior urethra (strongly associated with length of the sphincter, length of the urethral stump and the presence of anastomotic stricture) was the independent risk factor for permanent incontinence or delayed continence following RRP. The age of patients per se represented a risk factor only for delayed continence, but not for permanent incontinence.
CONCLUSIONS: Postoperatively measured shorter posterior urethral length results in an increased risk of urinary incontinence and delays continence after RRP. It seems that older age only delays reaching continence.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 34 participants or records.
