Purpose : When the mature kidney fails to reach its norml location in the renal fossa, the condition is known as ectopic kidney. Presenting symtoms can be various and it generally depend on the associated anomaly. Beside urologic anomalies such as hydronephrosis and vesicoureteral reflux, various anomalous vascular net work, skeletal anomaly or genital anomaly can be observed in this condition.
Methods : Sixteen children with ectopic kidney was studied retrospectively to analyse initial presentation, accompanied anomaly and prognosis.
Results : 56% of the children were accompanied with other urologic anomalies such as true incontinence and vesicoureteral reflux that required surgical treatment. 31% of children were either diagnosed incidentally during evaluation of other non-urologic disease or during follow-up evaluation of abnormal antenatal renal sonogram.
Conclusion : Ectopic kidney can be often misdiagnosed as tumorous condition or as a surgical condition depend on the abnormal location of the kidney. Careful evaluation using abdominal sonogram, DMSA, VCUG and abdominal CT scan should be performed in order to search for associated anomalous condition and for proper management.
