    Abstract:
    OBJECTIVE: To evaluate the difference in vesicourethral anastomotic stenosis (VUAS) rates after open radical retropubic prostatectomy (RRP) vs robot-assisted radical prostatectomy (RARP), and to analyze associated factors and effect on quality of life. METHODS: From 2001 to 2009, a total of 1038 patients underwent RARP and 707 patients underwent open RRP. Perioperative factors and Expanded Prostate Cancer Index Composite (EPIC) quality of life scores were compared between patients who did and did not develop a VUAS. Independent significant predictors of VUAS development were identified using multivariable modeling. RESULTS: The incidence of VUAS in open RRP cases was higher (53/707, 7.5%) than for RARP (22/1038, 2.1%) (P<.0001). Intervention consisted of dilation in 34 of 75 cases (45.3%), internal urethrotomy in 8 of 75 (10.7%), and multiple procedures in 30 of 75 (40%). Open technique (P<.0001, odds ratio [OR]=3.0, 95% confidence interval [CI]=1.8-5.2), prostate-specific antigen (PSA) recurrence (P=.02, OR=2.2, 95% CI=1.2-4.1), postoperative hematuria (P=.02, OR=3.7, 95% CI=1.2-11.3), urinary leak (P=.002, OR=6.0, 95% CI=1.9-19.2), and urinary retention (P=.004, OR=3.5, 95% CI=1.5-8.7) were significant independent predictors of VUAS development. EPIC incontinence scores were similar between VUAS and non-VUAS patients, whereas irritative voiding scores were worse initially with VUAS but became similar by 12 months. CONCLUSION: There is a higher rate of VUAS after open RRP vs RARP. Most cases of VUAS require endoscopic intervention. Predictors include open surgery, PSA recurrence, and postoperative hematuria, urinary leak, and retention. There is no diminution of quality of life scores at 12 months.
