Comparative long-term risks of chronic kidney disease and dialysis following conservative treatment, renal artery embolization, or nephrectomy in patients with blunt kidney injuries: retrospective cohort study.
Article in BJS open, 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
backgroundLong-term changes in renal function following blunt kidney injury (BKI) remain insufficiently studied, particularly in patients who undergo renal artery embolization (RAE). The aim of this study was to clarify the long-term risks of chronic kidney disease (CKD) and dialysis in patients with BKI after unilateral nephrectomy, RAE, or conservative treatment. The hypothesis was that both unilateral nephrectomy and RAE would increase these risks compared with conservative treatment, with RAE posing a lower risk.
methodsThis retrospective cohort study used data from Taiwan's National Health Insurance Research Database from 2001 to 2019, focusing on patients with BKIs. Outcomes included long-term CKD risks, lifelong dialysis, and all-cause mortality. Inverse probability of treatment weighting was used to minimize confounding.
resultsDuring the study, 19 013 patients were diagnosed with BKIs; of these, 12 709 were analysed (unilateral nephrectomy, 274 (2.1%); RAE, 510 (4.0%); conservative treatment, 11 925 (93.8%)). The mean(standard deviation) age was 39.7(17.1) years, 69.4% were male, and the mean follow-up duration was 10.7(5.2) years. Compared with conservative treatment, patients undergoing unilateral nephrectomy (subdistribution hazard ratio (SHR) 1.97; 95% confidence interval (c.i.) 1.86 to 2.10) or RAE (SHR 1.17, 95% c.i. 1.09 to 1.26) had a higher risk of CKD. In addition, patients in the nephrectomy and RAE groups had an increased risk of lifelong dialysis, with an SHR of 3.97 (95% c.i. 3.09 to 5.10) and 1.46 (95% c.i. 1.07 to 1.99), respectively. Unilateral nephrectomy was associated with a higher risk of all-cause mortality than RAE and conservative treatment, with hazard ratios of 1.14 (95% c.i. 1.06 to 1.23) and 1.63 (95% c.i. 1.52 to 1.75), respectively.
conclusionsPatients with BKIs are at higher risk of long-term CKD and potential lifelong dialysis after both unilateral nephrectomy and RAE, with RAE presenting a lower risk than nephrectomy. Patients with BKIs who undergo unilateral nephrectomy or RAE require follow-up to monitor renal function and receive health education on kidney protection.
