Retrograde intrarenal surgery in a non-fused left crossed ectopic kidney with large renal calculus: a case report and review of literature.
Article in Oxford medical case reports, 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
Crossed renal ectopia is a rare congenital anomaly, with non-fused variants being exceptionally uncommon. The management of nephrolithiasis in such kidneys is challenging due to the abnormal anatomy, malrotation, and altered ureteral course. We report a case of a non-fused left crossed ectopic kidney with a 21 × 14.5 mm with density of 1250 HU renal calculus successfully managed with retrograde intrarenal surgery (RIRS), achieving complete stone clearance (SC). This case highlights the feasibility of RIRS, even in complex renal anomalies with a significant stone burden. A review of the existing literature further supports the expanding role of RIRS in anomalous kidneys.
