Prospective observational study of oxidative stress in the pathology of benign prostatic hyperplasia with bladder diverticulum.
Observational study in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
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 < 0.0001), WBC counts (7.0 ± 1.9 vs. 4.2 ± 1.3 × 10⁹/L, p < 0.0001), residual urine volume (400.1 ± 252.0 mL vs. 150.7 ± 93.9 mL, p < 0.0001), and oxidative stress markers, including 8-OHdG (1.93 ± 0.58 vs. 1.70 ± 0.73 ng/mg creatinine, p = 0.014) and MDA (2.46 ± 0.57 vs. 2.03 ± 0.57 μmol/L, p < 0.0001). In group A, 8-OHdG positively correlated with residual urine volume (rho = 0.68) and nitric oxide with bladder wall thickness (rho = 0.70), while quality of life (QoL) negatively correlated with nitric oxide (rho = -0.76). In group B, oxidative stress markers correlated positively with BMI (e.g., homocysteine, rho = 0.69) and bladder wall thickness (e.g., nitric oxide, rho = 0.69), with QoL negatively correlated with uric acid (rho = -0.78).
conclusionsBladder diverticulum in BPH patients is associated with elevated oxidative stress, increased inflammation, and impaired bladder function.
