Hydronephrosis due to Ureteropelvic Obstruction in Children: A Review of 18 Cases / 대한비뇨기과학회지

ABSTRACT

From January 1976 until December 1980 we treated 12 male and 6 female children between the ages of 1 month and 15 years for ureteropelvic obstruction. Diagnosis was based on excretory urography and retrograde pyelography. The male and female ratio was 21. The patient in this series were distributed from 1 month old to 15 years old. The obstruction was on the left side in 10 cases, on the right side in 5 and bilateral in 3. Of the patients 7 presented because of an abdominal mass and 6 because of flank pain. The pathologic lesion encountered at ureteropelvic obstruction, are intrinsic ureteropelvic obstruction in 16 aberrant blood vessel in 1 and fibrous band in 2. Dismembered pyeloplasty was done in 10 cases, and nephrectomy in 9 cases. Preliminary nephrostomy was done in 3 cases. And secondary nephrectomy in 1 case. Of the 10 repairs 9 were protected by nephrostomy drainage plus ureteral stent.
