The impact of urinary extravasation after radical retropubic prostatectomy on urinary incontinence and anastomotic strictures.
OBJECTIVE
The aim of this study was to determine the relevance of urinary extravasation as proven by cystogram 18 days after radical retropubic prostatectomy for the degree of postoperative urinary incontinence and the incidence of anastomotic strictures.


METHODS
A total of 225 patients underwent radical retropubic prostatectomy at our institution during a 30-month period, 215 of whom received a cystogram a mean 18 days following surgery. Three and 6 months after surgery these 215 patients were evaluated regarding the degree of urinary incontinence and the presence of anastomotic strictures.


RESULTS
The cystogram demonstrated a watertight anastomosis in 89% (n = 195; group I), the remaining 11% (n = 24; group II) showed urine extravasation. Groups I and II were comparable with respect to age, preoperative serum levels of prostate-specific antigen (PSA), tumor grade and pathological staging. Six months after surgery, there was no statistically significant (p > 0.05) difference between both groups regarding the degree of urinary incontinence and the presence of anastomotic strictures.


CONCLUSIONS
The presence of urine extravasation 18 days after radical retropubic prostatectomy has no impact on postoperative urinary incontinence and the incidence of anastomotic strictures. Based on these data it is not indicated to leave the catheter in situ beyond that point of time.
