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 and Methods: 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. |
