Abstract Purpose: This study evaluates the management and long-term outcomes of pediatric patients under one 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. Methods: A 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. Results: No significant difference in hydroureteronephrosis grade (SFU) was observed between the two groups (p Conclusions: Both 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 one year old with these conditions.
