Abstract
Objectives
To elucidate whether a modified technique for anterior reconstruction could improve urinary continence after robot-assisted laparoscopic radical prostatectomy (RALP).
Methods
Among 325 consecutive patients who underwent RALP at our hospital, 297 patients were included in this retrospective study, who had complete records including the status of postoperative urinary continence. Among these 297 patients, 194 underwent anterior reconstruction by suturing the lateral bladder wall to the arcus tendineus of the pectineal fascia without fixation of the vesicourethral anastomosis site to the dorsal vein complex (DVC) (lateral-suture group). In the remaining 103 patients, simple suturing of the bladder neck muscle layer at the vesicourethral anastomosis site with DVC to immobilize the vesicourethral anastomosis site (immobilized group) was performed. Those who did not required a pad was defined as continent.
Results
Operative and console times were significantly shorter in the immobilized group (242 vs. 268 min; p = 0.03, and 174 vs. 203 min; p = 0.009, respectively). Although there was no significant difference between the groups regarding the recovery of urinary continence within 3 months after RALP (21 vs. 22% at 1 month; p = 0.77, and 54 vs. 60% at 3 months; p = 0.33, respectively), more patients achieved urinary continence in the immobilized group than lateral-suture group after 6 months (71 vs. 83% at 6 months; p = 0.03 and 82 vs. 96% at 12 months; p = 0.001, respectively).
Conclusions
Simple suture of the bladder neck muscle layer at the vesicourethral anastomosis site to DVC led to a better urinary continence status 6 months or later after RALP.
