Comparative outcomes of primary ureteral reimplantation vs. staged cutaneous ureterostomy in infants under one with primary obstructive megaureters and vesicoureteral reflux: a multi-center analysis.

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
purposeThis study evaluates the management and long-term outcomes of pediatric patients under 1 year of age with primary obstructive megaureters (POM) and vesicoureteral reflux (VUR), comparing primary ureteral reimplantation (PR) to a two-stage approach involving cutaneous ureterostomy (CU) followed by reimplantation.
methodsA multi-institutional study was conducted between 1994 and 2024, including 28 pediatric patients under 12 months of age. Participants were divided into two groups: PR (n = 14) and CU (n = 14). Comprehensive preoperative assessments, including renal ultrasound, voiding cystourethrography, and radionuclide diuretic renal scans, were performed. Surgical indications were based on recurrent UTIs, impaired renal function, or progressive hydronephrosis.
resultsNo significant difference in hydroureteronephrosis grade (SFU) was observed between the two groups (p < 0.05). In the PR group, two children required additional surgeries due to recurrent UTIs. Similarly, in the CU group, two children underwent subsequent ureteral reimplantation. The mean age at primary surgery was 6.9 months for the PR group, compared to 4 months for ureterostomy in the CU group (p < 0.05). The average operation time was 110.5 min for PR, vs. 64 min for CU (p < 0.05). Overall, more complications occurred in the group of children with CU until a definitive repair was performed.
conclusionsBoth primary ureteral reimplantation and the two-stage approach with cutaneous ureterostomy followed by reimplantation demonstrated effective outcomes in managing POM and VUR in infants. Given the findings, primary ureteral reimplantation may be considered a safe and effective approach in infants under 1 year with these conditions.
