Local anesthesia for transperineal prostate biopsy performed under sedation: effects on intraoperative and postoperative narcotic use.
Article in World journal of urology, 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
purposeTo investigate whether patients undergoing sedated prostate biopsies benefit from administration of local anesthetic. MATERIALS AND
methods880 transperineal prostate biopsies were done under sedation at our institution between November 2022 and December 2023. We assessed the effect of bupivacaine on pain severity during post-anesthesia care unit (PACU) stay, use of narcotics in PACU, length of PACU stay, and urinary retention. Multivariable logistic regression was used for pain score and narcotics use outcomes; multivariable linear regression for PACU length of stay and intraoperative propofol use; and univariable logistic regression for urinary retention.
results340 patients received bupivacaine, 334 did not. Ten patients (3.0%) who received bupivacaine and 30 (9.0%) who did not had maximum PACU pain scores ≥ 5 (95% CI 3.5%-12%, p < 0.001). Nine (2.6%) in the bupivacaine group and 31 (9.3%) in the no-bupivacaine group received narcotics (95% CI 4.4%-13%, p < 0.001), indicating significantly higher risk of needing narcotics among patients not receiving bupivacaine. We found no evidence of an effect of bupivacaine use on PACU LOS (β -0.08 h, 95% CI -0.20-0.03, p = 0.15) or urinary retention (OR 0.78, 95% CI 0.19-2.99, p = 0.7). Bupivacaine was associated with less intraoperative fentanyl (IRR 0.67, 95% CI 0.50-0.89) but more propofol (adjusted difference 48 mg, 95% CI 25-71, p < 0.001).
conclusionLocal anesthetic at the time of sedated transperineal prostate biopsy reduces both intraoperative and postoperative narcotic use and causes less post-procedure pain. A randomized study to confirm this finding is warranted.
