Congenital Renal arteriovenous malformation: An unusual cause of clot retention - Case report and review of the literature.
Article in Urology 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
A 35-year-old male with no prior medical or surgical history presented with clot retention. Cystoscopy revealed bloody efflux from the left ureteral orifice. Ureteroscopy showed clots within the left lower renal moiety. CT angiogram and renal angiography confirmed a renal arteriovenous malformation (AVM) that was successfully embolized. To our knowledge, this is the first reported case of a congenital renal AVM in a duplex collecting system. Prior cases of congenital renal AVM presenting with gross hematuria are reviewed. This is an unusual cause of gross hematuria in patients, which occasionally can be severe. Nonetheless, selective angioembolization provides excellent outcomes.
