Improvement in early continence after introduction of periurethral suspension stitch in robotic prostatectomy

Early urinary incontinence remains a major source of morbidity for patients undergoing robotic prostatectomy. The purpose of the study was to determine whether the introduction of a suspension stitch would improve early urinary continence rates in patients undergoing robotic prostatectomy for localized prostate cancer at our department. We retrospectively reviewed patients undergoing robotic prostatectomy with either suspension (n = 119) or figure-of-eight (n = 48) stitching of the dorsal venous complex. The patients submitted EPIC-26 questionnaires before surgery and after 3 and 18 months, respectively. Logistic regression analysis was run to determine the effect of the suspension stitch, nerve-sparing, posterior reconstruction, prostate volume, age and body mass index on early continence rate. The odds ratio of experiencing urinary leaks was 2.1 times higher (95% CI 1.0–4.3) in the figure-of-eight stitch group compared to the suspension stitch group 3 months after surgery (p p p = 0.1). Ordinal regression analysis identified the suspension stitch, bilateral nerve-sparing and body mass index as independent predictors of urinary continence at 3 months. The association between urinary continence and either unilateral nerve-sparing, posterior reconstruction, prostate volume or age did not reach statistical significance. Our results suggest that the suspension stitch improved early urinary continence following robotic prostatectomy.
