Abstract:
We report a case of giant hydronephrosis due to congenital ureteropelvic junction obstruction in a 7-month-old female infant with contralateral renal agenesis. Congenital renal agenesis is an uncommon congenital condition that results from a failure of induction of the metanephric blastema by the ureteral bud and fifteen per cent of cases show anomalies of the contralateral kidney. An excretory urogram and abdominal CT scan of the patient revealed nonvisualization of left kidney, and a retrograde pyelogram showed markedly dilated extrarenal pelvis crossing over the mid-line because of narrowing of ureteropelvic junction. However, the other combined anomalies were not identified. A successful dismembered pyeloplasty was performed after temporary urinary diversion with percutaneous nephrostomy for 4 weeks.
