We sought to compare the VUAS rate between minimally invasive (MIS) and open RP cohorts amongst United States veterans. METHODS: We queried the Veterans Affairs (VA) Corporate Data Warehouse for patients who underwent retropubic RP between 2003 and 2021 by CPT code (55840, 55845, 55866) were included. Patients who did not have a biopsy at the VA. Possible selected covariates were age, preoperative prostate specific antigen (PSA), agent orange exposure, body mass index (BMI), selected comorbidities based on ICD codes, and MIS surgery defined by the CPT code 55866. The primary outcome was undergoing a transurethral incision of a postoperative bladder neck contracture (TUIBNC) within 2 years of surgery by CPT code (52640). The secondary outcome was undergoing any incontinence procedure within 2 years of RP by male sling and artificial urinary sphincter CPT codes. Multivariate logistic regression was performed on the primary and secondary outcome. Stepwise selection was used for model building and restricted cubic spline terms were used for continuous variables. All statistics were performed in R, version 4.0.5. RESULTS: 32,776 patients were included in the analysis. Median patient age was 62 years old and median PSA was 6.04. 57.8% underwent open RP, and 42.3% underwent MIS RP. Overall TUIBNC and incontinence procedure cases within 2 years of surgery were 292 (0.9%) and 725 (2.2%), respectively. Median time to TUIBNC was 8.0 months. On multivariate analysis, after adjusting for age, PSA, and a history of congestive heart failure (CHF), the risk of TUIBNC remained higher with open surgery (OR 7.1, CI 4.7-11.4 p <0.001). Figure 1 shows the rate of MIS RP, open RP, and TUIBNC over time. On multivariate analysis, after adjusting for age, BMI, a history of myocardial infarction, CHF, and diabetes, incontinence surgery within 2 years of surgery was higher after open RP (OR 1.29, CI 1.08-1.53, p 0.004). CONCLUSIONS: Compared to MIS RP, open RP was associated with a 7-fold increase in rate of VUAS and a 1.3-fold increase in the rate of incontinence requiring a procedure within 2 years of surgery at the VA.
