Effectiveness and Safety of Image-Guided Renal Biopsies: Insights from 5,235 Procedures in the German Society for Interventional Radiology and Minimally Invasive Therapy (DeGIR) Registry.
Article in Cardiovascular and interventional radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThis study evaluates the technical success, diagnostic yield, and complication rates of image-guided percutaneous renal biopsies based on multicenter registry data from the German Society for Interventional Radiology and Minimally Invasive Therapy. MATERIALS AND
methodsThis retrospective analysis included 5,235 renal biopsies at 176 centers in Germany, Austria, and Switzerland between 2018 and 2024. Technical success was defined as image-guided confirmed needle placement within the target lesion. Diagnostic yield is defined as proportion of procedures providing adequate samples for clinical diagnosis.
resultsCT was used for image guidance in 78.53% followed by ultrasound in 12.32%. Technical success was 98.38% and diagnostic yield 94.92%. Technical success was high in both inpatients (98.33%) and outpatients (99.26%; OR = 0.44, 95%CI 0.11-1,80; p = 0.241). The overall complication rate was 5.04%, with major complications in 0.74%. Complications were more frequent with pathological platelet counts and INR values, but none of these coagulation parameters remained independently associated in multivariable analysis. CT-guided biopsies showed higher complication rates than ultrasound-guided procedures, and this association remained after adjustment (adjusted OR 8.57, 95%CI 3.40-21.58; p < 0.001). No fatal complications occurred within 24 h; however, three delayed deaths were documented among hospitalized patients.
conclusionPercutaneous image-guided renal biopsies are effective and safe, with low complication rates and high diagnostic yield. Ultrasound guidance remained independently associated with a lower complication risk, likely reflecting selection bias.
