| Summary: | Objective:This study aimed to assess and compare the conventional and Retzius-sparing robot-assisted radical prostatectomy (cRARP and RsRARP) in term of perioperative clinical, pathological, and oncological outcomes.Materials and Methods:This study included 238 consecutive male patients who underwent RARP between May 2008 and November 2020. RARP operations were performed by a single-surgeon. Patients were divided into groups according to the surgical approach and were statistically compared in terms of perioperative clinical, final pathological, and oncological outcomes.Results:The mean age of patients was 64±7 years. cRARP was performed in 134 (56.3%) patients, whereas RsRARP in 104 (43.7%). The frequency of patients with the American Society of Anesthesiologists Class-2 score was higher in the RsRARP group (p<0.001). The median surgery duration was 300 (270-360) min. The median surgery duration was shorter in RsRARP group (290 vs. 330 minute) (p<0.001). No difference was found between the groups in terms of estimated blood loss and postoperative complication rates (p=0.112 and p=0.182, respectively). No difference was found between the groups when they were compared for surgical margin positivity (p=0.453). Although not statistically significant, the frequency of surgical margin positivity with pT3a/pT3b disease was higher in patients who underwent cRARP (p=0.412 and p=0.261, respectively). At a median follow-up of 13 (6-36) months, no difference was found between the groups in terms of biochemical recurrence at months -3,-6,-9,-12,-18,-24, and -30, respectively (p>0.05, for each).Conclusion:RsRARP allows a safe operation with a shorter surgical time and similar surgical margin positivity, oncological outcomes, and complication rates compared to cRARP.
