Psychological and anatomical determinants of pain have rarely been compared within a single model, and MRI-derived perineal anatomical parameters have not been evaluated. We aimed to identify factors associated with procedural pain and to determine at which step pain peaks. Methods: In this prospective, pre-registered, single-centre cohort study (OSF: osf.io\/pbacu), 182 consecutive men referred for transperineal MRI\u2013ultrasound fusion biopsy under local anaesthesia were assessed for eligibility, and 177 constituted the Full Analysis Set. State anxiety was measured with the STAI-S before and after biopsy. Pain was rated on a Numeric Rating Scale (NRS 0\u201310) by a nurse not involved in the procedure at four predefined steps: probe insertion, skin infiltration, periprostatic nerve block and core sampling. Midline perineal tissue thickness (MPT) and levator ani thickness were measured on pre-biopsy T2-weighted MRI by a radiologist blinded to outcomes. The primary outcome was the maximum NRS score; ten candidate predictors were entered simultaneously into a multivariable linear regression model. Results: Clinically significant pain (maximum NRS score \u2265 4) was reported by 157 of 177 men (88.7%). Pain differed markedly across steps (F(2.68, 472.39) = 230.51, p &lt; 0.001, partial \u03b72 = 0.567) and peaked at the periprostatic nerve block (5.88 \u00b1 2.03), exceeding core sampling by 2.62 points (95% CI 1.85\u20133.40). In multivariable analysis (R2 = 0.192), pre-biopsy anxiety was the strongest independent predictor (standardised \u03b2 = 0.30, partial R2 = 0.094, p &lt; 0.001), followed by prostate volume (\u03b2 = 0.19, p = 0.014); MPT showed only an exploratory, borderline association (\u03b2 = 0.17, p = 0.052). Core number, body mass index and levator ani thickness were not associated with pain. Conclusions: Most men undergoing transperineal MRI-fusion biopsy experience clinically significant pain, peaking at administration of the periprostatic block rather than at core sampling. Pre-procedural anxiety and prostate volume, both available beforehand, support simple risk stratification, while the block itself is the most logical target for analgesic improvement.<\/jats:p>","DOI":"10.3390\/diagnostics16193195","type":"journal-article","created":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T18:43:24Z","timestamp":1790880204000},"page":"3195","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Factors
