Comparison of oncological and functional outcomes of perineoscopic radical prostatectomy and robot-assisted radical prostatectomy.

Abstract

The aim of this study is to compare the functional, oncological, and complication outcomes of perineoscopic radical prostatectomy (PeRP) and robot-assisted radical prostatectomy (RARP) operations. Patients who underwent radical prostatectomy (RP) between October 2018 and June 2020 for localized prostate cancer (N0, < T3) were retrospectively screened. After the exclusion criteria, 56 patients who underwent PeRP and 67 patients who underwent RARP remained in the study. Demographic, perioperative, and postoperative data were collected. In functional outcomes, continence and potency status were compared at 1, 3, 6, and 12months. The mean age of the patients was 61.3 ± 5.9years in the PeRP group and 62.2 ± 5.7years in the RARP group. No statistically significant differences were present between preoperative and postoperative values. Among the perioperative findings, the mean operation time was 90.4 ± 11.2min for the PeRP group and 114.6 ± 14.7min for the RARP group. The operation time was shorter in the PeRP group. The average hospital stay was 2 ± 0.6days in the PeRP group and 2.3 ± 0.5days in the RARP group. It was significantly shorter in the PeRP group. There is no statistically significant difference between the two groups in the oncological and functional results. PeRP is a surgical procedure safe in low-risk patients with medium-risk prostate cancer (PCa) who do not require lymph-node dissection. Moreover, PeRP minimizes the difficulties of perineal surgery.
