Objective:To prove the effectiveness of puboprostatic ligament-preserving robotic-assisted laparoscopic radical(RARP)on enhancing early continence.Methods: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.Results: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.Conclusions:Use of puboprostatic ligament-sparing RARP could be a method to accelerate early continence without affecting the final oncological outcome.
