Simultaneous antegrade-retrograde endoscopic procedures for the placement of thermo-expandable metallic stents in the treatment of ureteral stenosis in kidney transplantation patients: A cohort study.
Article in The Journal of international medical research, 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
ObjectiveTo evaluate the efficacy and safety of simultaneous antegrade-retrograde endoscopic rendezvous procedure for thermo-expandable metallic stent (Memokath 051) placement in treating post-kidney transplantation ureteral stenosis.MethodsA retrospective single-arm cohort study was conducted in six female patients with distal ureteral strictures after kidney transplantation treated between 2022 and 2024. A dual-endoscope technique was used for stent deployment. Surgical parameters, laboratory indicators, and complications were recorded, with a follow-up period of 1-20 months. Paired t-tests or Wilcoxon tests were applied for statistical analyses.ResultsAll stents were successfully placed, with a mean operative time of 173.0 min and mean hospital stay of 8.8 days. Hydronephrosis was significantly relieved in all patients. Postoperative estimated glomerular filtration rate was significantly higher than the preoperative rate
