Ectopic pelvic kidney in a child: A case report

Abstract

Ntroduction. An ectopic pelvic kidney is an anatomical anomaly in the position of the kidney. In the stage of metanephros, its movement, rotation, and lifting from the pelvis to the lumbar area are absent. Due to vascular or other abnormalities, the kidney does not reach its usual anatomical position and therefore remains ectopic. The position in which it can be placed is retroperitoneal, abdominal, or thoracic, with numerous variations. Case report: A three-month-old male infant underwent kidney screening during an ultrasound examination of the hips. There had been a positive family history in the mother and maternal aunt of the existence of an ectopic, left pelvic kidney, without complications and accompanying symptoms. The clinical findings of the infant's systems were normal, he was developing in terms of body mass. The analyzes of urine, biochemistry, and urine culture did not show any pathological findings. Ultrasound examination showed that the left renal lobe was completely filled with spleen, without visualization of the left kidney. In the right lumbar box, there was the right kidney, with regular dimensions, clear edges and normal thickness of the parenchyma. Inferior to the right kidney, in the area of the right lumbar region, facing inwards, there was the left kidney with regular ultrasonographic characteristics. Urinary bladder was properly positioned, with normal dimensions and wall thickness. The infant was advised to see a pediatric nephrologist. Conclusion: This is another case of an ectopic kidney recorded during an echosonographic examination of the hips, thus demonstrating the importance of routine ultrasound examinations of the abdomen, in order to increase the possibility of early detection of anomalies of the abdominal organs.
