ABSTRACT

Ectopic kidney is the result of an abnormality in the migration of the ureteral bud and metanephric blastema towards the renal fossa. Location can be thoracic, iliac, pelvic, and/or crossed, with or without fusion with the contralateral kidney unit.
Objective: To present a case of closed abdominal trauma in a patient with crossed fused ectopic kidney and excluded kidney function.
Clinical case: Patient is a 37-year-old man who was admitted to the emergency room for macroscopic hematuria secondary to closed abdominal trauma. Study protocol was carried out and plain and contrasted abdominal film showed bilateral ectopic kidney with right kidney in pelvic position and left kidney in pelvic position that was crossed fused at right kidney inferior pole. Hematuria stopped spontaneously 72 hours after commencement of conservative treatment. Kidney scintigram showed functional exclusion of left kidney and so patient underwent left nephrectomy 2 months after hematuria event. There were no complications from the procedure and patient had good postoperative progression. He was released from the hospital on the fourth postoperative day.
Discussion: Ectopic kidney with or without fusion is a congenital disorder not frequently seen that can progress asymptomatically. However, its association with vesicoureteral reflux and obstructive uropathy may lead to kidney function deterioration. These patients should be managed with function tests and concomitant anatomical variations should be determined in order to carry out adequate surgical procedure.
