Abstract
Background: Ureteropelvic junction obstruction (UPJO) is a common cause of hydronephrosis in infants and young children and may lead to renal deterioration if untreated. Objective: To evaluate outcomes of open translumbar mini-incision Anderson–Hynes pyeloplasty in infants and young children.
Methods: Retrospective analysis of 30 pediatric patients (2015–2024). All underwent ultrasound, MAG-3 scintigraphy, and retrograde evaluation with DJ stenting. Outcomes included operative time, complications, and recovery.
Results: 17 males (56.7%) and 13 females (43.3%) were included. Antenatal diagnosis was present in 80%. Mean operative time was 80–176 minutes. Early mobilization occurred in 90% of patients. No recurrence or urine leakage was observed. One conversion to pyelostomy occurred.
Conclusion: Mini-incision open pyeloplasty is safe and effective with excellent outcomes in infants and young children.
