Retzius-sparing robot-assisted radical prostatectomy: Perioperative and immediate continence outcomes of an initial...

The objective of this work is to present initial perioperative, immediate continence and oncological results in a series of 25 prostate cancer patients treated with Retzius-sparing robot-assisted radical prostatectomy.

We retrospectively analyzed a series of 25 patients treated with Retzius-sparing robot-assisted radical prostatectomy for cT1-T2b prostate cancer between 2018-2019. The 5 stages of surgery are described. We make a descriptive statistic of our initial series and its outcomes in terms of immediate continence, defined as the use of 0 pad/diapers or 1 safety pad/diaper every 24 hours, one week after catheter removal.

Median follow-up, 6 months (3-18). Median PSA, 6.1 ng/ml (4-14.3). All surgeries were performed through a posterior intrafascial approach, and bilateral nerve-sparing was carried out in 84% of the cases. Affected surgical margins were present in 28%, being the apex the most frequent site of affectation. Surgical complications: 1 (4%) patient required transfusion of blood products in the immediate postoperative period. Mean hospital stay was 48 hours. Functional outcomes: 80% of the patients present immediate continence. 80% of continent patients do not require the use of any safety pads/diapers. Oncological outcomes: 84% are free of biochemical-progression in a median follow-up of 6 months.

Initial functional results in terms of immediate continence are very satisfactory in patients who have undergone Retzius-sparing robot-assisted radical prostatectomy without negative impact on prognosis.
