Abstract

We compare the diagnostic impact of 2 diuresis renography techniques for evaluation of suspected upper urinary tract obstruction in children. A total of 72 children were randomly assigned to 1 of 2 standardized diuresis renography protocols. The protocols were identical, except for the time of furosemide (F) injection. In the F+20 scans furosemide was given 20 minutes after the 99mtechnetium pentetic acid radiopharmaceutical. With the modified F-15 scans furosemide was injected 15 minutes before renography. Hydration, bladder catheterization, urine output determination, radiopharmaceutical injection and scan acquisition were identical. Renography outcomes (obstructed, nonobstructed or equivocal) were analyzed for the investigated side(s) and for the contralateral side, which was used as a control in children with suspected unilateral obstruction. Chi-square test was used to compare the percentage of obstructed and nonobstructed scans of both protocols. Fisher's exact test was used to compare the nonobstructed scans and equivocal results of both protocols. Of the 96 scans performed 8 were excluded because of technical problems. The remaining scans included 44 F+20 and 44 F-15. Of the 88 scans 10 were used to evaluate possible bi...Continue Reading
