Is Urethral Catheterization Necessary in Retzius-sparing Robot-assisted Radical Prostatectomy?

Objective To analyze whether urethral catheter (UC)-free anastomosis during Retzius-sparing radical prostatectomy (RP) results in worsening immediate perioperative and postoperative complications. Methods We retrospectively reviewed records of patients undergoing robotic-assisted RP with or without indwelling UC placement by a single surgeon between January 2020 and March 2022. Clinical and pathological characteristics were evaluated. An independent t-test was used to compare continuous variables, and Pearson's chi-square test or Fisher exact test was used to compare categorical variables. Results One hundred fifteen patients underwent robotic prostatectomy from January 2020 to June 2022. Sixty-two patients had both a UC for 12 hours postoperatively and a suprapubic catheter for 6 days, while in 53 patients a UC was omitted. There was no significant difference noted between the groups regarding age, body mass index, American Society of Anesthesiology score, prostate-specific antigen, stage, node status, or positive margins. There were no significant differences in the rates of anastomotic leak, ileus, or urethral stricture. Patients had a significantly higher pad-free rate in the suprapubic catheter-only group (P = .04) at 3 months. There was no difference in average number of pads used or the number using more than 1 pad/day. Conclusion Omission of urethral catheterization during Retzius-sparing RP is safe and doesn't result in an increased risk in perioperative or postoperative complications, but rather appears to be associated with a significantly improved 3-month pad-free rate.
