title: Sensitivity of 131I-hippuran diuresis renography and pressure flow study (Whitaker test) in upper urinary tract obstruction.
abstract: Diuresis renography and pressure flow studies were performed in 14 patients with unilateral hydronephrosis. Based upon the results of intravenous pyelography, typical symptomatology, and the outcome of surgical treatment, all patients were found to have upper urinary tract obstruction. It was therefore possible to calculate the sensitivity of the two tests. Obstruction was found at the pressure flow studies in 7 of 14 patients (50%), while an obstructive pattern was found at diuresis renography in 12 of 13 patients (92%). Due to a very low glomerular filtration rate, diuresis renography was equivocal in 1 case. Based upon these results, diuresis renography seems to be superior to pressure flow studies in cases with upper urinary tract obstruction.
