ABSTRACT

Objective To evaluate diuretic renogram (DR) in the assessment of therapeutic effect on dilated upper urinary tract in children. Methods A total of 54 children with 66 sides of dilated upper urinart tract undergone surgery had been followed up by DR examination. Results According to the renal blood perfusion rate (BPR),the dilated upper urinary tract was divided into 3 catagories,the minor,medium and the major.In minor and medium catagories (49 sides),the renogram on 37 sides changed from obstructive pattern (no excretory phase) to reduced excretion ones which slopped downward obviously on frusemide administration (dilated nonobstructed pattern).The renogram had no change on 12 sides.In the major catagory (17 sides),BPR changed from 23.8?3.5% preoperatively to 33.4?6.4% postoperatively ( P
