For assessment purposes, ultrasonography (US) was taken at month 1-3 postoperatively and mercaptoacetyltriglycine
(MAG-3) scintigraphy at month 6 postoperatively and, the follow-up intervals were planned accordingly.
If the MCUG shows no reflux, a mercaptoacetyltriglycine
(MAG3) scan is ordered depending on the severity of the case according to our institution protocol [Figure 1].
A DMSA (dimercaptosuccinic acid) scan showed 36% function of the right kidney and a MAG-3 (mercaptoacetyltriglycine
) renogram suggested moderate to severe right pelviureteric junction (PUJ) obstruction but with preserved renal function.
The visualization quality (even with a weak kidney function) of [sup.99m] Tc-technephore is comparable to that of tubulotropic [sup.99m]Tc-MAG3 (mercaptoacetyltriglycine
) and 123I-hippuran, significantly outperforming conventional glomerulotropic [sup.99m]Tc-DTPA (diethylenetriaminepentaacetic acid) .
The ectopic left kidney had a relative function of 40% in conventional technetium-99m (Tc-99m) mercaptoacetyltriglycine
Only 2(7%) patients in group 1 and 2(4.5%) in group 2 had poor response on mercaptoacetyltriglycine
Comparison of differential renal function using technetium-99m mercaptoacetyltriglycine
(MAG3) and technetium-99m dimercaptosuccinic acid (DMSA) renography in a paediatric population.
(MAG3) is the most popular radiotracer used for this purpose.
- MAG3 Uses diuretic to evaluate suspected urinary tract obstruction.
The first diuretic renography (DR), using mercaptoacetyltriglycine
(MAG-3) was performed to all patients 8-12 weeks after birth.
(MAG-III) renal scan showed right-side obstruction with a split function of 41.1% on the right kidney.
