Ultrasound-based predictive indicators for treatment outcomes in pediatric vesicoureteral reflux

To evaluate the effectiveness of preoperative ultrasound (US) measurements in predicting pediatric vesicoureteral reflux (VUR) treatment outcomes. This prospective study enrolled 35 patients (53 renal units) aged 1–16 years who underwent subureteric injection therapy for primary VUR between July 2020 and June 2022. Preoperative ultrasound examinations measured the bladder wall thickness at the ureteral orifice, ureteral submucosal tunnel length, distal ureteral diameter, patient demographics, VUR grade, presenting complaints, bladder–bowel dysfunction, and renal scarring, and the impact of these variables on treatment success was analyzed. Among the patients, 91.4
