ABSTRACT
BACKGROUND:
Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) has been shown to lead to better outcomes regarding early continence compared to standard anterior RARP (SA-RARP). The goal of this study was to assess the feasibility and safety of implementing RS-RARP in a tertiary center with experience in SA-RARP.METHODS:
From February 2020, all newly diagnosed non-metastatic prostate cancer patients for whom RARP was indicated were evaluated for RS-RARP. Data from the first 100 RS-RARP patients were prospectively collected and compared with data from the last 100 SA-RARP patients. Patients were evaluated for Clavien Dindo grade ≥3a complications, urinary continence after 2 and 6 weeks, 3, 6 and 12 months, erectile function, positive surgical margins (PSMs) and biochemical recurrence (BCR).RESULTS:
There was no significant difference in postoperative complications at Clavien-Dindo grade ≥3a (SA-RARP 6, RS-RARP 4; p = 0.292). At all time points, significantly higher proportions of RS-RARP patients were continent (p < 0.001). No significant differences in postoperative potency were observed (52% vs. 59%, respectively, p = 0.608). PSMs were more frequent in the RS-RARP group (43% vs. 29%, p = 0.034), especially in locally advanced tumors (pT3 64.6% vs. 43.8%, p = 0.041-pT2 23.5% vs. 15.4%, p = 0.329). The one-year BCR-free survival was 82.6% vs. 81.6% in the SA-RARP and RS-RARP groups, respectively (p = 0.567). The median follow-up was 22 [18-27] vs. 24.5 [17-35] months in the RS-RARP and SA-RARP groups, respectively (p = 0.008).CONCLUSIONS:
The transition from SA-RARP to RS-RARP can be safely performed by surgeons proficient in SA-RARP. Continence results after RS-RARP were significantly better at any time point. A higher proportion of PSMs was observed, although it did not result in a worse BCR-free survival.Palavras-chave
