Abstract
OBJECTIVES: To examine the incidence, effectiveness of intervention, effect on continence, and factors predisposing to the occurrence of anastomotic strictures following radical retropubic prostatectomy. METHODS:Between January 1994 and June 1999, 753 radical retropubic prostatectomies were performed by a single surgeon. Anastomotic strictures were managed by dilatation followed by a self-catheterization regimen. Dilatations were repeated unless more than three dilatations were required over a 9-month interval. A control group representing a randomly selected group of men who did not develop anastomotic strictures was identified. The largest width of the midline vertical abdominal scar was measured. RESULTS: Of the 753 radical retropubic prostatectomies, 36 (4.8%) developed an anastomotic stricture. The mean time interval between the surgical procedure and diagnosis of the stricture was 4.22 months. Of the 26 cases of anastomotic strictures with at least 1-year follow-up, 24 (92.3%) were managed successfully by dilatations alone. No baseline characteristics before surgery were associated with the development of a stricture. The maximal scar width was the only factor that was associated with the development of a stricture in this study. Men with a maximal scar of greater than 10 mm were eight times more likely to develop strictures than men with smaller scars. The percentage of men who required protective pads 1 year following radical retropubic prostatectomy in the control and stricture groups was 12.5% and 46.2%, respectively. CONCLUSIONS:Anastomotic strictures are relatively rare following radical prostatectomy and have a negative effect on the development of continence. Most men are successfully managed with dilatations alone. The development of anastomotic strictures in some men appears to be related to a generalized hypertrophic wound-healing mechanism.
