Giant Congenital Hydronephrosis Obstructing the Gastro Intestinal System and the Contralateral Kidney in a New Born.

ABSTRACT

A 5 day old baby, with known left hydronephrosis which discovered by prenatal US presented with gastrointestinal tract obstruction. Laboratory work up demonstrated abnormal renal function and metabolic acidosis combined with hyperkalemia. Radiology tests showed bilateral hydronephrosis with huge left renal pelvis crossing the midline and causing deviation of the gut laterally. This acute presentation beside inability to receive oral feeding made us prefer immediate left renal drainage with pyelostomy in order to restore renal function, relieve the pressure effect of the huge renal pelvis and stabilize the baby. Dismembered pyeloplasty was done at age of 3 months.
