Abstract
- Clinical and radiological observation was made on the 42 cases of childhood hydronephrosis patients admittedto Hanyang University Hospital from June, 1972 to August, 1982. Performed diagnsotic methods were exccretoryurography, retrograde pyelography, voiding cystourethrography and other advanced form of radiological methods suchas angiography or ultrasonography. The resultls were as follows; 1. The male patient were more frequent thanfemale patient and its ratio was 29:13. 2. 18 out of 42 patients were below 5 years of age and 9 of them were lessthan 1 year old. 3. Abdominal mass was the common presenting feature especially on obstructive hydronephrosis.Genitourinary symptoms or flank pain was the most frequent compliant in older children. Nongenitourinary symptomswere also noted especially in nonobstructive hydronephrosis of young children. 4. Obstructive hydronephrosis were26 cases and nonobstructive hydronephrosis were 17 cases. Pelviureteric junction was most frequent obstructionsite and intrinsic stricture was more frequent than extrinsic lesion. Vesicoureteric reflux and recurrent urinarytract infection was the frequent causes of nonobstructive hydronephrosis. 5. Both kidneys are equally affedted inall of cases. The left side was more frequently affected in obstructive hydronephrosis cases. 6. Voidingcystourethrography was performed in 14 cases and showed V-U reflux in 8 cases especially of mild nonobstructivehydronephrosis. 7. Ultrasonography was performed in 10 cases and it was the good method for diagnosis especiallywhen the abdominal mass was the presenting feature in children. 8. Most of operated cases were severe, grade IIIor IV, obstructive hydronephrosis cases. 9. Associated abnormalities affecting the genitourinary tract was foundin 17 cases. Nongenitourinary tract abnormalities were present in 20 cases especially associated with spinalanomaly.
