Diuretic renal scintigraphy was developed in the late 1970s as a noninvasive method for diagnosing and following patients with obstructive uropathy.<sup>18 Koff S.A., Thrall J.H., Keyes J.W. Assessment of hydronephrosis in children using diuretic radionuclide urography J Urol 1980 ;  123 : 531-534

The initially described technique has been modified over the years in an attempt to improve the specificity and accuracy of the test.<sup>5 Choong K.K.L., Gruenewald S.M., Hodson E.M. , e al.
