Predictors of clinically significant hemorrhage following ultrasound-guided percutaneous renal biopsy in pediatric patients.
Article in Pediatric radiology, 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
backgroundUltrasound-guided percutaneous renal biopsy is a cornerstone in the evaluation of pediatric kidney disease, with post-biopsy hemorrhage being the most common complication. Multiple predictors of post-biopsy bleeding have been identified in the adult population; however, data on risk factors in children is limited.
objectiveThe purpose of our study is to determine any risk factors of post-biopsy hemorrhage in children. MATERIALS AND
methodsThis IRB-approved retrospective study included pediatric patients who had native or transplant renal biopsy between 2010-2024. The primary outcomes included decrease of hemoglobin of >15 g/L measured 4-6 h post biopsy and/or presence of a sizable perinephric hematoma (defined as ≥5 mL) measured on immediate post-biopsy ultrasound. The association between presence of hematoma and significant change in Hb was assessed, and the association of 12 different preselected risk factors with these co-primary outcomes was analyzed.
resultsAmong 207 patients included (median age 11 years [IQR, 7-14]), 170 (82%) underwent native kidney biopsy and 37 (18%) transplant kidney biopsy. A post-biopsy hemoglobin decrease ≥15 g/L occurred in 23 patients (11%; 95% CI, 8-16%), and 27 (13%; 95% CI, 9-18%) developed a sizable perinephric hematoma. A hematoma ≥5 mL on immediate post-procedural imaging was associated with a hemoglobin decrease ≥15 g/L (OR 4.6, 95% CI 1.5-13.4; P=0.004). No other factors were significantly associated with hemoglobin decline or hematoma after correction for multiple testing.
conclusionImmediate post-biopsy ultrasound findings may help predict clinically significant post-biopsy hemorrhage, while no other risk factors were identified.
