ABSTRACT
PURPOSE:
The purpose of this study was to evaluate the accuracy of Tc-99m DTPA diuretic renal scans in children upper urinary tract. MATERIALS ANDMETHODS:
We reviewed diuretic renal scans of 14 pediatric patients (age range 3 days to 4 years) with unilateral hydronephrosis diagnosed by ultrasonography. Diuretic renal scan was done using Tc-99m DTPA and standardized protocol. In 3 neonates, diuretic renal scans were performed within 1 week and 3-7 months after birth.RESULTS:
Six patients required pyeloplasty and eight were managed conservatively. All 6 patients requiring pyeloplasty were diagnosed as having ureteropelvic junction obstruction in the diuretic renal scan. In these 6 patients, post-operative renal scans at 3-12 months after surgery were converted to nonobstructive pattern in 5 and a nonobstructive patterns in 1. In 3 patients who underwent diuretic renal scan within 1 week after birth., nonobstructive patterns of initial scan were coverted to obstructive patterns in the follow-up scan. However, all patients with nonobstructive diuretic renal scans performed after the neonatal period did well on serial ultrasonography and showed favorable clinical outcome without progression to obstruction.CONCLUSION:
Tc-99m DTPA diuretic renal scan with standarized protocol is useful in assessing suspected ureteropelvic junction obstruction in children as an initial diagnostic or post-operative follow-up modality. Nonobstructive or indeterminate scan RESULTS in the neonatal period requires follow-up scan to monitor development of the obstructive pattern.
