Superselective renal artery embolization for complex duplex kidney with multiple prior surgeries: a case report.
Article in Frontiers in 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
Duplex kidney is a common congenital malformation appearing as duplication of the renal pelvis and ureter. However, complex cases with a history of multiple abdominal surgeries, extensive perirenal adhesions, aberrant vascular anatomy, and long-term anticoagulation remain challenging to manage, and no standardized protocol currently exists. Herein, we report a 54-year-old female patient with a complex duplex kidney who had a history of multiple previous abdominal and renal surgeries, long-term oral warfarin anticoagulation, and concurrent recurrent urinary tract infections, renal abscess, and upper urinary tract stones. Following multidisciplinary team evaluation, traditional heminephrectomy was considered extremely high-risk; consequently, superselective renal artery embolization was performed as definitive treatment. The patient recovered uneventfully without major complications. At 12-month follow-up, all symptoms completely resolved, renal function remained stable, and no recurrence of infection or stones was observed. This case suggests that for patients with complex duplex kidney at high surgical risk, superselective renal artery embolization is a safe and feasible minimally invasive alternative, and may inform individualized clinical decision-making.
