Summary
Current cigarette smoking and comorbidities like CAD, HTN, and DM significantly increase bladder neck contracture (BNC) risk after radical prostatectomy (RP). Smoking is the strongest predictor, but treatments like transurethral dilation are effective.
Area of Science:
- Urology
- Surgical Oncology
- Medical Comorbidities
Background:
- Bladder neck contracture (BNC) is a potential complication following radical prostatectomy (RP).
- Microvascular disease-associated comorbidities may impair anastomotic healing, contributing to BNC development.
- Identifying preoperative risk factors is crucial for managing and preventing BNC.
Purpose of the Study:
- To investigate preoperative risk factors for BNC after RP.
- To evaluate the relationship between comorbidities and BNC incidence.
- To review the management and treatment outcomes for BNC.
Main Methods:
- Retrospective review of 467 patients undergoing RP.
- Analysis of preoperative comorbidities (CAD, DM, HTN, smoking) as potential risk factors.
- Evaluation of prior TURP, EBL, and OR time for BNC prediction using univariate and multivariate analysis.
Main Results:
- 11.1% of patients developed BNC.
- Current cigarette smoking was the strongest predictor (26% BNC rate), independent of other factors.
- Comorbidities including CAD, HTN, and DM were associated with increased BNC rates; longer OR time and greater EBL were also observed.
Conclusions:
- Preoperative comorbidities linked to microvascular disease are significant risk factors for BNC post-RP.
- Current cigarette smoking is a particularly strong predictor of BNC.
- Transurethral dilation and incision are equally effective initial treatments for BNC, with no impact on continence.
