Partial Distal Ureteral Obstruction After Pediatric Kidney Transplantation: A Diagnostic Challenge.
Article in Cureus, 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
Ureteral complications are a significant source of morbidity after kidney transplantation. While complete ureteral obstruction is typically identified with standard imaging, partial obstruction may be more difficult to diagnose. We report the case of an eight-year-old girl who developed progressive hydronephrosis and graft dysfunction following kidney transplantation. Imaging studies, including ultrasound and retrograde pyelography, were inconclusive and failed to clearly localize the obstruction. Due to persistent graft dysfunction, surgical exploration was performed, revealing a short-segment distal ureteral stenosis approximately 1 cm from the vesical implantation site, consistent with segmental ischemia. The ureterovesical anastomosis was intact. Ureteral reimplantation resulted in the resolution of obstruction and recovery of graft function. Partial ureteral obstruction may be difficult to detect with standard imaging and should be considered in cases of unexplained graft dysfunction.
