Diuretic radionuclide localization of upper urinary tract obstruction.
In 59 children with proved upper urinary tract obstruction diuretic radionuclide ureteral scans provided an accurate assessment of ureteral dilatation sufficient to distinguish ureteropelvic from ureterovesical obstruction. As a result, this test may be used instead of more invasive studies, such as retrograde or antegrade pyelography, to determine the site of obstruction in many cases of hydronephrosis.
