Low Rate of Urological Complications in Pediatric Kidney Transplantation Using a Stentless Ureteral Anastomosis.
Article in Pediatric transplantation, 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
backgroundPediatric kidney transplant recipients are susceptible to a range of complications that may compromise allograft function and are associated with significant morbidity. Urologic complications represent an important subset that may necessitate multiple radiological and/or surgical interventions.
methodsOur previously reported modified extravesical ureteroneocystostomy technique was designed to avoid routine stent placement at the time of transplant as well as to reduce postoperative urologic complications. Here, we reviewed 107 consecutive pediatric kidney transplant recipients transplanted at our center since 2014 who received no stent placement at the time of transplant.
resultsThe observed percentage who developed a urologic complication during the first 12 months post-transplant was 3.7% (4/107), and only 2.8% (3/107) required surgical intervention. Ureteral obstruction/stricture was observed in 2.8% (3/107), with two being due to UPJ obstruction, and one being due to the occurrence of multiple kidney stones that occluded the distal ureter/ureterovesical junction (UVJ). No urinary leaks, 0.0% (0/107), were observed during the first 12 months post-transplant. Additionally, poor bladder compliance along with Grade 4 vesicoureteral reflux occurred in one patient. One patient (who developed a UPJ obstruction) was successfully managed with interventional radiology alone. The other three patients required surgical intervention: ureteral reimplantation for the patient having UVJ obstruction due to multiple kidney stones, pyeloureterostomy in one patient with a UPJ obstruction, and bladder augmentation along with (ureter, ileum, and ileal) Monti Mitrofanoff in the patient having poor bladder compliance.
conclusionsIn pediatric kidney transplantation, our extravesical ureteroneocystostomy technique without routine ureteral stent placement was associated with a low incidence of post-transplant urological complications.
