Association between prostatic inflammation and detrusor overactivity in men with benign prostatic hyperplasia and bladder outlet obstruction: a prospective urodynamic and histological study.
Observational study in Prostate cancer and prostatic diseases, 2026. 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
backgroundBenign prostatic hyperplasia (BPH) frequently leads to bladder outlet obstruction (BOO) and lower urinary tract symptoms (LUTS) in aging men. Detrusor overactivity (DO) is a common functional consequence of BOO, often persisting even after surgical intervention. Prostatic inflammation (PI) has been implicated in BPH pathogenesis, but its relationship with DO remains unclear. This study aimed to evaluate the association between histologically confirmed PI and DO in men undergoing transurethral resection of the prostate (TURP) for BPH-related BOO.
methodsWe conducted a prospective, observational study involving 125 men aged ≥50 years with BPH, BOO confirmed by pressure-flow studies, and moderate-to-severe LUTS (IPSS ≥ 7). All patients had received standard medical therapy and were candidates for TURP. Urodynamic testing was performed before and three months after surgery. Based on baseline urodynamic findings, patients were categorized into two groups: those with DO (Group A) and those without (Group B). Resected prostate tissue was examined histologically, and PI was graded using the Irani score. Statistical analysis was performed using SPSS v26, with odds ratios (OR) and 95% confidence intervals (CI) reported.
resultsProstatic inflammation was identified in 78.4% of patients overall and was significantly more prevalent in those with DO (84.9% vs. 69.2%; OR = 2.47, 95% CI: 1.11-5.49, p = 0.02). Inflammation was also more severe in Group A. DO resolved postoperatively in 75.3% of patients, while persistent DO was associated exclusively with moderate-to-severe PI. The odds of persistent DO following TURP were significantly higher in this subgroup (OR = 4.00, 95% CI: 1.33-12.05).
conclusionsProstatic inflammation is more frequent and severe in men with DO and is associated with its persistence after TURP. These findings suggest that PI contributes to both the pathogenesis and postoperative course of DO, supporting its role as a therapeutic target in BPH-related LUTS management.
