[Continence recovery after robotic-assisted radical Retzius-sparing prostatectomy].

OBJECTIVE

To assess time to urinary continence recovery after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) and to describe early perioperative and oncological outcomes.

MATERIALS AND

METHODS

A retrospective analysis was performed of patients who underwent RS-RARP in 2022-2024. The primary endpoint was time to complete urinary continence (0 pads/day). Time-to-event analysis (continence recovery) was carried out using the Kaplan-Meier method, with cumulative event probability visualized as (1S(t)) and 95% confidence intervals calculated.

RESULTS

A total of 344 patients were included. On day 1 after urethral catheter removal, complete continence was observed in 90,1% of patients (0-1 pad/day in 97,3%). Complete continence rates were 92,1% at 1 month and 97,2% at 12 months. Mean time to continence recovery was 0,7 months (95% CI 0,428-0,973). Positive surgical margins were detected in 9% of cases; no biochemical recurrence was recorded during follow-up. Mean operative time was 113 min and mean blood loss was 121 mL.

CONCLUSIONS

RS-RARP provides rapid recovery of urinary continence with high early complete continence rates and acceptable perioperative and short-term oncological outcomes. Comparative studies versus standard RARP and comprehensive analyses of oncological and functional outcomes are needed to further clarify the advantages and limitations of this technique.
