We report a neonate with a giant urinoma and renal failure. A 7-day-old boy had a giant abdominal mass of 6.5 cm x 8 cm in the right quadrant, gastroesophageal reflux, and renal failure caused by the compression from the mass. Radiological observations revealed a multiseptated cyst and neither kidney could be detected. To relieve these symptoms percutaneous drainage was performed. The contents of the fluid were similar to the patient's urine. The symptoms were improved by the drainage, and we found the left kidney to be absent and the right kidney small. Four prenatal ultrasound scans detected no cystic lesions in his abdomen. Neonatal urinomas are commonly complicated by obstructive uropathy, such as posterior urethral valves or ureteropelvic junction obstruction. These obstructive uropathies were ruled out by retrograde pyelography and voiding cystourethrography. A severely dilated upper pole of a double collecting system was also ruled out by intravenous pyelography and direct observation of the kidney during an open biopsy. The cause of the urinoma is still uncertain, but trauma during delivery and the dysplastic right kidney may be involved.
