Effect of puboprostatic ligament preservation during robotic-assisted laparoscopic radical prostatectomy on early continence: Randomized controlled trial.

To prove the effectiveness of puboprostatic ligament-preserving robotic-assisted laparoscopic radical (RARP) on enhancing early continence.

Ninety-two patients with localized adenocarcinoma of the prostate scheduled for RARP from April 2018 to January 2019 were prospectively single-blinded and randomized into two groups, standard RARP (Group A) and puboprostatic ligament-sparing RARP (Group B). The outcomes were continent status at Foley catheter removal and 3 months after surgery using the score from the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF), pad usage, pathological margin status, blood loss, operative time, and complications.

Ninety-six patients were randomized (46 patients in each group), with a mean±SD age of 67.30±6.07 years. There were no differences in baseline characteristics. At 3 months after surgery, ICIQ-UI SF score (mean±SD) in Group A was significantly higher than Group B (8.74±4.28 vs. 6.93±3.96, p=0.038) but no difference at Foley catheter removal. Group A also had a significant higher score for interference with daily life (median [interquartile range, IQR]: 4 [1, 5] vs. 2 [0, 4]; p=0.041) and higher pad use (median [IQR]: 2 [0, 3] vs. 1 [1, 2]; p=0.041) at 3 months. One case in Group A had complete or severe incontinence (>5 pads/day) at 3 months. Groups A and B did not exhibit significant difference in margin status (p=0.828). There were no differences in operative time, blood loss, drain output or complications.

Use of puboprostatic ligament-sparing RARP could be a method to accelerate early continence without affecting the final oncological outcome.
