Basic information of both groups.

BackgroundOxidative stress contributes to benign prostatic hyperplasia (BPH) pathogenesis, but its role in BPH with bladder diverticulum is unclear.MethodsThis prospective cohort study compared 126 BPH patients at the Second Hospital of Harbin Medical University. The study involved two groups (n = 63 for each group): group A, comprising patients with BPH, and group B, consisting of BPH patients with bladder diverticulum. Ultrasound imaging and CT scans were employed to assess the features of BPH and bladder diverticulum, respectively. Various clinical parameters and oxidative stress biomarkers were compared between the groups.ResultsGroup B exhibited significantly higher creatinine (101.8 ± 27.6 µmol/L vs. 56.1 ± 23.6 µmol/L, p ConclusionsBladder diverticulum in BPH patients is associated with elevated oxidative stress, increased inflammation, and impaired bladder function.
