End-to-Side Reconstruction for Two Renal Arteries Affects the Recovery of the Graft Function in Living Donor Renal Transplantation.
Article in Cureus, 2025. 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
BACKGROUND/
objectivesKidneys with multiple arteries are occasionally encountered in living-donor renal transplantation. However, the impact of different reconstruction methods on graft outcomes remains unclear. Therefore, we aimed to analyze the effect of the end-to-side reconstruction technique on short- and long-term outcomes in living donor renal transplantation.
methodsWe retrospectively analyzed 254 living donor renal transplants performed at our center between 2011 and 2024. Sixty patients with dual renal arteries were categorized into five groups based on the type of reconstruction method: end-to-side (n=5, 2.0%), inferior epigastric artery (n=15, 5.9%), direct anastomosis (n=2, 0.79%), side-to-side (n=29, 11.4%), and ligated (n=9, 3.5%). Furthermore, we compared the incidence of early postoperative events and long-term survival with those of a control group of single-artery transplants. Long-term survival was analyzed using Kaplan-Meier and Cox regression analyses. Cox regression was adjusted for several factors.
resultsThe end-to-side group had a significantly higher incidence of delayed graft function recovery (p<0.001) and a trend toward increased all-cause graft loss (p=0.254) compared with the control group, whereas other groups showed no significant difference.
conclusionsOur study showed a higher incidence of delayed graft renal function recovery and inferior long-term graft survival only in the end-to-side group. Further multicenter studies are required to evaluate alternative reconstruction techniques.
