Abstract

Aim: To evaluate the clinical characteristics, associated anomalies, and outcomes of children diagnosed with renal ectopia in a single tertiary care center.
Materials and Methods: We retrospectively reviewed medical records of 58 children with renal ectopia followed between January 2024 and June 2025. Data on demographics, anomalies, laboratory findings, imaging, and treatments were analyzed.
Results: Among 58 patients (mean age 71.6 ± 56.4 months; 33 females, 25 males), 26 patients (44.8%) had right renal ectopia and 32 patients (55.2%) had left renal ectopia. Crossed renal ectopia was present in 9 patients (15.5%), of whom 7 (77.8%) had crossed-fused renal ectopia. Additional urogenital anomalies included hydronephrosis in 7 patients (12.1%), neurogenic bladder in 4 patients (6.9%), and vesicoureteral reflux in 3 patients (5.2%). Prenatal diagnosis was achieved in 4 patients (6.9%). Consanguinity was noted in 28 patients (48.3%), and 11 patients (19.0%) had a family history of congenital anomalies of the kidney and urinary tract (CAKUT). Voiding cystourethrography performed in 12 patients (20.7%) identified high-grade vesicoureteral reflux in 3 patients. Among 53 patients who underwent DMSA scintigraphy, renal scarring was detected in 8 patients (15.1%); of these, one patient had hypertension, one had proteinuria, one was followed with stage 2 chronic kidney disease, and one with stage 5 chronic kidney disease.
Conclusion: Renal ectopia may be accompanied by additional urogenital anomalies. Early diagnosis and comprehensive evaluation are essential for optimal management and prognosis.
