Abstract

Currently, the risk factors for bladder diverticula in patients with benign prostatic enlargement remain unclear. Therefore, this study aimed to identify independent risk factors and provide a clinical reference for early risk screening of this complication.
A total of 310 patients diagnosed with benign prostatic enlargement between January 2021 and December 2024 were included in this retrospective study. General clinical data and relevant clinical indicators were collected, and risk factors were identified through univariate and multivariate logistic regression analyses.
Among the 310 patients with benign prostatic enlargement, 21 had bladder diverticula, representing an incidence of 6.77%. Multivariate logistic regression analysis revealed that total prostate volume (odds ratio [OR] = 1.067, 95% confidence interval [CI]: 1.023-1.113, P = .002) and intravesical prostatic protrusion (OR = 1.135, 95% CI: 1.056-1.219, P < .001) were independent risk factors for bladder diverticula in patients with benign prostatic enlargement.
Bladder diverticula occurred in 6.77% of patients with benign prostatic enlargement in this cohort. Total prostate volume and intravesical prostatic protrusion are independent risk factors for this complication and may serve as clinical markers for risk evaluation.
