Diuretic renography is the most widely used noninvasive test for chara
cterization of the renal functional abnormalities resulting from urete
ropelvic junction obstruction. Since O'Reilly and colleagues introduce
d the procedure to clinical practice in the late 1970s, numerous modif
ications and improvements to the technique have been introduced. This
review provides an overview of diuretic renography as well as an updat
e regarding recent consensus reports that outline preferred standard p
