Abstract

INTRODUCTION: Retzius sparing prostatectomy was promoted with the early continence result. The long-term oncological outcome is still unknown. In this study, we aimed to compare the Intermediate-term oncologic outcomes of these two approaches in patient's cohort who was treated as part of a randomized controlled trial.

METHODS: A total of 120 patients were previously randomized equally to receive retzius sparing (RS-RARP) versus standard robotic assisted laparoscopic radical prostatectomy (S-RARP) between January 2015 to April 2016. Baseline, surgical, and pathological characteristics as well as oncologic outcomes were assessed. The analysis was done based on the treatment received.

RESULT: Sixty-three patients underwent S-RARP while 57 patients underwent RS-RARP. There was no statistically significant difference in the baseline nor surgical characteristics. The median follow up was 71.24 (IQR 59.75 - 75.75). There were more pathological T3 diseases in RS-RARP. There was no significant difference in the positive margin status nor the biochemical recurrence rate among both groups. After S-RARP and RS-RARP, 6 and 10 patients had biochemical recurrence and the 5-years biochemical recurrence free survival were 91% and 85%, respectively. (p= 0.21).

Conclusion: In this cohort, there was no difference in biochemical recurrence in the patients who received either technique. Further mutli-institutional studies with a larger sample size and longer follow up are required.
