Abstract

© 2021 AEUIntroduction and objectives: We aim to compare the first year oncological and functional outcomes of Retzius-sparing robot-assisted radical prostatectomy (Rs-RARP) and standard robot-assisted radical prostatectomy (RARP). Materials and methods: Eighty-eight patients who underwent robotic radical prostatectomy between 2018-2019 were included. We compared the minimum one-year follow-up results of patients who underwent Rs-RARP or RARP in terms of oncological and functional outcomes. Potency was assessed with the Sexual Health Inventory for Men (SHIM) score and was defined as an erection sufficient for penetration. Continence was defined as the absence of urinary incontinence with no safety pad. Patients were evaluated in the first month of follow-up and subsequently, every three months. Results: Forty-six patients in Rs-RARP and 42 patients in the RARP group were enrolled. Catheter removal time was shorter in the Rs-RARP group (12 vs. 14 days, P = .001). At the 1st month visit, 41 patients (%89) were continent (no pads) in the Rs-RARP group while 25 patients (%59) were continent in the RARP group (P = .001). Patients who underwent Rs-RARP achieved faster recovery of urinary continence (Log-rank, P = .001). After one year of follow-up, 43 patients (93%) in Rs-RARP group and 38 patients (90%) in RARP group were continent (P = .6). Potency rates were 38.7% in Rs-RARP and 34.4% in RARP group (P = .28). There were no cases of biochemical recurrence in any group. Conclusions: Rs-RARP is a feasible technique, providing early return of continence. However, overall continence rates were similar at the end of the one-year follow-up.
