The results of free uroflowmetry, filling cystometry, and pressure-flow study were analyzed to evaluate functional parameters. For anatomical parameters, bladder trabeculation grade, lateral lobe protrusion of prostate, and bladder neck elevation (BNE) measured in cystourethroscopy were used. BOO was defined as the BOO index of 40 or higher in UDS. Bladder trabeculation was graded using our previous studies.Results: Among total of 1,452 BPH patients, 1,028 patients had trabeculation on cystoscopy. Age, serum prostate-specific antigen, postvoid residual, total prostate volume, transition zone volume, terminal type detrusor overactivity, detrusor pressure at the maximal flow rate, bladder contractility index (BCI), and BOO index increased according to increase in bladder trabeculation. Multivariable logistic analysis showed that bladder trabeculation was significantly associated with age (odds ratio [OR], 1.05; P&lt;0.001), kissing sign (OR, 1.55; P=0.007), BNE (OR, 1.76; P&lt;0.001), detrusor overactivity (OR, 1.88; P=0.002), BCI (OR, 1.01; P=0.037), BOO (OR, 2.27; P&lt;0.001). BOO had the greatest correlation with bladder trabeculation. In addition, BOO index showed a positive correlation (r=0.39, P&lt;0.001) with bladder trabeculation. BOO index well distinguished between moderate trabeculation of grade 2 or higher in receiver operating characteristic analysis (area under curve=0.72, P&lt;0.001).Conclusions: Our results showed that the severity of BOO is positively associated with the severity of bladder trabeculation.<\/jats:p>","DOI":"10.5213\/inj.2550362.181","type":"journal-article","created":{"date-parts":[[2026,6,29]],"date-time":"2026-06-29T00:33:08Z","timestamp":1782693188000},"page":"127-136","update-policy":"https:\/\/doi.org\/10.5213\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect
