Evaluation of urinary extravasation and results after continence-preserving radical retropubic prostatectomy.

Objective: To evaluate the feasibility of urinary catheter removal 10 days after a radical retropubic prostatectomy (RRP) by assessing the incidence of urinary extravasation and its effect on postoperative stricture and continence rates.
Patients and Methods: During a 4.5-year period, 619 patients undergoing RRP were evaluated. If no extravasation was detected on gravity cystography, the urinary catheter was removed 10 days after RRP. In patients with significant extravasation the catheter was left in place for 3 weeks. Overall stricture and continence rates were recorded in patients at 3, 6 and 12 months after surgery.
Results: There was extravasation during cystography in 29 patients (4.6%). At 3, 6 and 12 months, continence rates after catheter removal at 10 days were 74.9%, 87.9%, and 93.6%, respectively, while in the late-removal group they were 72.4%, 84.6% and 90.9%, respectively, with no significant difference between the groups. At 3 months the overall continence rate was 74.8% and at 12 months up to 93.5%. There was no difference in stricture rates between the groups, with an overall stricture rate of 0.7%.
Conclusions: Catheter removal 10 days after RRP is feasible, giving excellent early and late continence rates, with low anastomotic stricture rates obtained using good surgical technique. Extravasation at 10 days was rare and with proper management did not influence the final results.
