Objectives
The vesicoprostatic muscle (VPM) is a longitudinal smooth muscle that originates from the trigone of the bladder or the opening of the ureter and is involved in urination as part of the detrusor apron. We explored the effect of VPM reconstruction on immediate and early recovery of urinary continence in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALP).
Patients and methods
A total of 523 patients with localized prostate cancer were enrolled from June 2018 to June 2020. All patients were diagnosed in our department based on magnetic resonance imaging and pathological findings on prostate biopsy. After 1:1 propensity score matching, 105 patient pairs were matched. The study was approved by our institutional review board and all surgeries were performed by three experienced high-volume surgeons. Demographic data, total operation time, pathological outcomes, the urinary continence rates of the two groups at different times after RALP, and factors influencing postoperative urinary continence after RALP were recorded. Student’s t test was used to compare continuous variables and the Pearson χ2 test to compare categorical variables. Logistic regression analysis was used to identify factors affecting immediate and early postoperative urinary control.
Results
VPM reconstruction promoted immediate and early recovery of urinary continence (immediate continence, 66.67 vs. 40.00%, P = 0.000; 3-month continence, 80.95 vs. 64.76%, P = 0.008).
Conclusions
VPM reconstruction improved immediate and early urinary continence in patients who underwent RALP.
