Renal outcomes of children with ectopic kidneys: A single-center experience

Abstract

Aim: This study aimed 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 the medical records of 58 children with renal ectopia who were followed up between January 2024 and June 2025. Data on demographics, anomalies, laboratory findings, imaging findings, and treatments were analyzed.

Results: Among 58 patients (mean age 71.6 ± 56.4 months; 33 females, 25 males), 26 (44.8%) had right renal ectopia and 32 (55.2%) had left renal ectopia. Crossed renal ectopia was present in 9 (15.5%) patients, of whom 7 (77.8%) had crossed-fused renal ectopia. Additional urogenital anomalies included hydronephrosis in 7 (12.1%), neurogenic bladder in 4 (6.9%), and vesicoureteral reflux in 3 (5.2%). Prenatal diagnosis was achieved in 4 (6.9%) patients. Consanguinity was noted in 28 patients (48.3%), and 11 patients (19.0%) had a family history of CAKUT. Voiding cystourethrography was performed in 12 patients (20.7%) and high-grade vesicoureteral reflux was identified in 3 patients. Renal scarring was detected in 8 (15.1%) of the 53 patients who underwent DMSA scintigraphy; of these, 1 patient had hypertension, 1 had proteinuria, 1 was followed with stage 2 chronic kidney disease, and 1 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.
