Clinical efficacy of laparoscopic Lich-Gregoir versus transvesicoscopic Cohen reimplantation for ureterobladder junction malformations in children.

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 assess the clinical efficacy of laparoscopic Lich-Gregoir (LLG) and transvesicoscopic Cohen reimplantation (TCR) in the treatment of vesicoureteral junction obstruction (VUJO) and vesicoureteral reflux (VUR).
methodsThis study retrospectively analyzed the clinical data of 66 pediatric patients with VUJO and VUR. They were classified into two groups, undergoing either the laparoscopic Lich-Gregoir operation (LLGO) (n = 35) or transvesicoscopic Cohen reimplantation operation (TCRO) (n = 31). The surgeries were performed between April 2018 and September 2022 at the First Affiliated Hospital of Guangxi Medical University, China. General characteristics, preoperative attributes, postoperative complications, renal function recovery, and improvement of hydronephrosis were compared between the two groups.
resultsAll surgical procedures were successful with no requirement for reoperation. Both groups were comparable with respect to gender, affected side, weight, and postoperative complications. Nonetheless, the LLGO group contained a greater number of children younger than 12 months. The LLGO group demonstrated superiority over the TCRO group regarding the duration of the operation, intraoperative blood loss, and length of postoperative hospital stay. In contrast, postoperative complications, recovery of renal function, and hydronephrosis improvement did not exhibit statistically significant differences between the two groups.
conclusionBoth LLGO and TCRO were demonstrated to be precise, safe, and reliable surgical methods for treating pediatric VUJO and VUR. LLGO ureteral reimplantation offers particular advantages in selecting cases and appears more suitable for children younger than 12 months who have a small bladder capacity.
