Only children with lack of improvement in hydronephrosis underwent diuretic nuclear renography
The distinction between renal artery stenosis and renal vascular hypertension explains the different roles of angiography and captopril renography in the management of these patients.
Renography clarifies the functional significance of hydronephrosis and/or hydro-ureter on anatomical imaging.
In his algorithm, patients at highest risk should have angiography, while those with moderate risk should have captopril renography
or duplex ultrasonography (depending on the expertise of the institution).
Eight patients underwent surgery secondary to a decrease in function on nuclear renography
, and only 50% returned to 90% of their baseline function.
Even people with modest renal insufficiency can be studied with diuretic renography
, although the furosemide dose may need to be altered in the setting of an elevated serum creatinine level.
2), (3) The role of renography
in children with moderate and severe hydronephrosis is to assist to identify children who need surgical intervention.
If the renal sonogram showed increasing hydronephrosis, diuretic renography
was repeated to confirm that renal function was stable.
Changes of renal flow in nephroptosis: assessment by colour Doppler imaging, isotope renography
and correlation with clinical outcome after laparoscopic nephropexy.
Intravenous urography and isotope renography
show the function of the orthotopic kidney, but also the lack of function in the ipsilateral lower mass and contralateral flank.
