Risk factors for acute kidney injury after nephron-sparing surgery in sporadic renal angiomyolipoma: a multicenter retrospective cohort study.
Article in BMC surgery, 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
backgroundAcute kidney injury (AKI) is a significant complication following nephron-sparing surgery (NSS) for renal angiomyolipoma (RAML). Identifying risk factors is crucial for perioperative management. This study aimed to investigate the independent risk factors for AKI following NSS in patients with sporadic RAML.
methodsA multicenter retrospective cohort study was conducted involving 413 patients who underwent NSS for sporadic RAML between January 2012 and December 2024 at seven tertiary urology centers. Patients were categorized into AKI and non-AKI groups based on KDIGO 2012 criteria. Univariate analysis and multivariate logistic regression were used to identify risk factors associated with postoperative AKI.
resultsAmong 413 patients, 65 (15.7%) developed postoperative AKI. Multivariate analysis identified four independent risk factors: elevated preoperative blood urea nitrogen (BUN) (OR = 1.30, 95% CI 1.09-1.55), higher RENAL nephrometry score (OR = 1.32, 95% CI 1.06-1.65), longer operative time (per 30-min increase: OR = 1.32, 95% CI 1.12-1.57), and prolonged renal artery occlusion time (OR = 1.09, 95% CI 1.04-1.15). The combined predictive model incorporating these four factors achieved a high specificity of 92.0% for AKI prediction, with favorable discriminative performance.
conclusionsPreoperative BUN level, RENAL score, operative time, and renal artery occlusion time are independent risk factors for AKI after NSS in sporadic RAML patients. These findings support enhanced preoperative assessment and targeted intraoperative strategies, such as minimizing ischemia time, to reduce AKI risk.
