Vesicourethral healing following radical prostatectomy: is it related to surgical approach?
OBJECTIVES. To explore how the occurrence of vesicourethral anastomotic strictures (bladder neck contractures [BNC]) following radical prostatectomy was dependent on these variables: postoperative urine extravasation, type of anastomosis, size of prostate, and surgical approach. METHODS. We retrospectively reviewed 143 cases over 36 months for the occurrence of early BNC (6 to 12 months follow-up). Voiding cystourethrograms (VCUC) were performed in all patients at 3 weeks. Radical retropubic prostatectomy (RRP) with direct anastomosis was performed in 93 cases, RRP and Vest anastomosis in 35 cases, and radical perineal prostatectomy (RPP) in 15 cases. RESULTS. The overall incidence of extravasation was 14.1%. Procedure-specific rates of incidence of extravasation were RPP 33.3%, RRP 18.1%, and radical retropubic with Vest anastomosis (Vest) 6.1%. Mean prostate weight was not significantly different between patients with or without extravasation. The anastomotic site was classified as being irregular (plicated) or smooth in appearance on the VCUG images. An irregular appearance was noted among 81% of the RRP, 42.4% of the Vest, and 40% of the RPP. Bladder neck contractures occurred in 29% of patients with Vest anastomosis, 14.1% with RRP, and none of the patients undergoing RPP. Only 1 patient in both the Vest and RRP group who experienced BNC was noted to have extravasation on VCUG at 3 weeks. CONCLUSIONS. We have noted that the type of anastomosis (Vest traction sutures) significantly increases the likelihood of early bladder neck contracture following radical prostatectomy. The presence of contrast extravasation on the postoperative VCUG study (implying urinary extravasation) did not influence the formation of an anastomotic stricture as long as patients were maintained with catheter drainage until resolution of extravasation. The appearance of the newly constructed bladder neck on the postoperative VCUG image was not predictive of a subsequent contracture.[1]References
