Diagnosis was confirmed based on renal ultrasound and diuretic nuclear renography
using Tc-99m MAG-3 clarifies the significance of hydronephrosis and/or hydro-ureter.
2,3] The role of renography
in children with moderate and severe hydronephrosis is to assist to identify children who need surgical intervention.
The differential renal function was assessed with computerized isotope renography
(DTPA renal scan) in selected patients.
14) Thus, the clinical setting and the use of further imaging such as diuretic renography
may be necessary to determine the functional significance of the appearance of a dilated collecting system.
and scintigraphy offer a noninvasive test and the ability to assess renal functional status.
demonstrated bilateral nonobstructive hydronephrosis with prompt drainage of both renal units.
Renal function changes were evaluated with nuclear renography
comparing glomerular filtration rate (GFR) percent during follow-up with the preoperative values.
The role of renography
in children with moderate and severe hydronephrosis is to help identify children who need surgical intervention.
Patients were evaluated with preoperative physical examination, intravenous urography, and diuretic renography
is performed with radioactive agents that are excreted either by glomerular filtration (99Tc-DPTA) or mainly by tubular secretion combined with glomerular filtration (99Tc-MAG3).
