Objectives: To determine if placement of urethral suspension stitches during radical retropubic prostatectomy improves postoperative urinary continence.
Methods: Between January 1997 and January 1998 we performed radical retropubic prostatectomy on 50 men. The first 25 consecutive men had their surgery without urethral suspension stitches while the next 25 received placement of two anastomotic urethral suspension stitches anchored to the lower portion of the pubic bone. Patients were interviewed six months postoperatively and each underwent valsalva leak-point pressure measurement. Patients were categorized as either completely continent (requiring no pads and having no measurable valsalva leak point), socially continent (zero or one pad per day), or incontinent (two or more pads per day).
Results: In the urethral suspension group, 8/25 (32%) patients were completely continent and did not have a measurable valsalva leak-point pressure while 3/25 (12%) without urethral suspension were completely continent. Of the remaining patients in the urethral suspension group, 13/17 (76%) patients were socially continent while 4/17 (24%) were incontinent. The mean valsalva leak-point pressure in the 17 patients with suspension stitches was 89.6 +/- 21.6 cm H2O. In the patients without urethral suspension, there were 22 patients who had some degree of incontinence. Among non-stitch patients, 13/22 (59%) were socially continent while 9/22 (41%) were incontinent. The average valsalva leak-point pressure in these patients was 74.0 +/- 16.7 cm H2O, which was significantly lower than those with the suspension (p = 0.015).
Conclusions: Placement of anastomotic urethral suspension stitches during radical retropubic prostatectomy may increase the likelihood of complete postoperative urinary continence. The urethral suspension stitches also increase valsalva leak-point pressure, which may improve the percentage of patients with socially acceptable incontinence.
