Is Retzius-sparing robot-assisted laparoscopic radical prostatectomy effective in early continence? A single-center experience of the first 50 patients.

OBJECTIVE

In this study, we aimed to present the perioperative and postoperative outcomes and early continence rates of the first 50 patients who underwent Retzius-sparing robot-assisted laparoscopic radical prostatectomy (RS-RALP) in our clinic for prostate adenocarcinoma.

MATERIAL AND METHODS

Between December 2018 and December 2019, 50 patients who underwent RS-RALP by 2 surgeons in our clinic were enrolled in the study. Preoperative, perioperative, and postoperative clinical data were analyzed retrospectively. Procedure-specific complications were graded according to the Clavien-Dindo classification. The continence status of the patients was recorded in the 1 week, 1 month, and 3 month after catheter removal. Zero pads or 1 safety pad per day was accepted as total continence.

RESULTS

The mean age of the patients was 66.6 (57-75) years. According to the D'Amico classification, 36% of patients were at low risk, 48% at intermediate risk, and 16% at high risk. Bilateral or unilateral nerve-sparing procedure was performed in 76% of the patients. There were no intraoperative complications. A total of 9 (18%) patients had a postoperative complication (7 with grade 1, 1 with grade 2, and 1 with grade 3 complications). Whereas 32% of the patients had an extraprostatic extension, 22% had seminal vesicle invasion. The overall positive surgical margin rate was 26%. At 1 week, 1 month, and 3 months after surgery, 64%, 80%, and 92% of men who underwent RS-RALP were continent, respectively.

CONCLUSION

Our study showed that this new surgical technique can be a safe and feasible method because high rates of early continence were achieved in the patients who underwent RS-RALP without increasing the risk of complications.
