In 2012, Demirel and his co-workers determined the differential renal function using DTPA or MAG3
and reported that reliable outcomes were acquired in dynamic renal scan.
The current imaging test of choice for the assessment of the function of a hydronephrotic kidney is the MAG3
diuretic renogram, as it permits assessment of both the differential renal function (DRF) and the drainage time.
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].
After obtaining a nuclear medicine renal scan with intravenous technetium 99m MAG3
showing significant decrease in left kidney function, the urology consultant recommended and performed a robot-assisted nephrectomy.
In our case, MAG3
noted bilateral rapid evacuation without abnormal findings giving us some advantage to avoid surgery for the right UPJO and safely monitor the period after parathyroidectomy until the complete dissolution of all kidney stones.

scan showing no perceptible renal activity.
The ectopic left kidney had a relative function of 40% in conventional technetium-99m (Tc-99m) mercaptoacetyltriglycine (MAG3
scan revealed complete loss of renal function of the left kidney.
Operative time, intraoperative estimated blood loss, presenting complaint, preoperative imaging, analgesic use, postoperative hospital stay, crossing vessel, complications and success rates based on postoperative mercaptoacetyltriglycine (MAG3
) scan at 6 months were compared for both groups.

Measurement of effective renal plasma flow (ERPF) with the help of para- aminohippuric acid (PAH) or radio pharmaceuticals like MAG3
etc is another method.
