While most experts suggest that pyeloplasty be considered in patients showing obstructed drainage and differential function below 40%, others propose surgery at differential function below 35%, or an obstructed renogram with prolonged [t.sub.1/2] > 20 min.
The authors also reported that [.sup.99m]Tc-DTPA can be used for the evaluation of relative renal function in subjects who need renogram curve and GFR calculations, whereas [.sup.99m]Tc-DTPA can be an alternative for the calculation of relative renal function.
The diuretic renogram should include a report of the DRF, which can vary between 45-55%, the cortical transit time which is normal up to 5 minutes, the half-time and the shape of the curve (31).

The objective of the present study is to create a ureteral obstruction experimental model that can be proved through renogram with technetium-99m diethylenetriaminepentaacetic acid ([sup.99m]Tc-DTPA) and histopathological studies, without causing total renal function loss.
It is tempting to interpret the drainage as shown on renogram curves, but this is not reproducible.
