ObjectiveTo investigate whether posterior and anterior fixation of the vesicourethral anastomosis during robotic radical prostatectomy (RRP) helps to establish continence earlier.Material And MethodsForty-seven consecutive patients undergoing RRP were randomized into two groups. The first group received a typical Van Velthoven vesicourethral anastomosis and the second group a modified anastomosis with posterior and anterior fixation. In this group the posterior fibrous tissues of the sphincter were sutured to the residual Denonvilliers' fascia. The anastomosis with two running sutures started at the 6 o'clock position on the bladder neck and continued upwards. Two-step stitching was done on the upper half of the anastomosis to ensure good stabilization of the bladder: a small portion of urethral stump followed by a deep haemostatic stitch on the plexus. Continence, as measured by patient self-reporting of the number of pads used per 24 h, was assessed 7 weeks after catheter removal, by telephone interview. The use of no pads or one pad was defined as "continent", two pads as "moderate incontinence" and more than two pads as "severe incontinence".ResultsAt catheter removal, more patients in the fixation group were continent than in the Van Velthoven group [9/23 (39%) vs 3/24 (12.5%), p = 0.036]. At 7 weeks, continence was even better in the fixation group [15/23 (65%) vs 8/24 (33%), p = 0. 029]. The mean pad usage was less in the fixation group (1.43 vs 2.25, p = 0.032).ConclusionsThe posterior and anterior fixation of the vesicourethral anastomosis during RRP results in an intact sphincteric mechanism, because no stretch is applied to the urethra, resulting in earlier continence.
