31I-labeled-O-iodohinpurate renograms in 15 cases of epidemic hemorrhagic fever(E.H. fever)during oliguric, diuretic and convalescent phase were analysed quantitatively and qualitatively, namely by its configuration, Tmax T 1!2 and renal index of Hirakawa.
The results were as following:
1) Changes on the renograms in E.H. fever showed simultaneous bilateral renal impairment. 2) The characteristic configurations of renogram in the oliguric phase were: 01 Moderately decreased absolute amplitude of initial spike.
Conti:aous rising second slope.
0 No appearance of terminal descent.
Those were most likely to those of renograms in acute ureteral obstruction or acute dehydration state.
3) Daring the diuretic phase, the renogram showed the point of maximal amplitude, but the steepness of 2nd slope was markedly decreased.
The appearance of terminal descents was observed with unusually high amplitude despite of the tremendously large amount of urinary output during this phase.
4) Ia convalescence, the renograms were essentially normal in configuration, but the renal index of Hirakawa was not recovered until this phase.
5) Renograms in E.H. fever showed the characteristic patterns in each phase of its clinical course.
6) 1311-01H-Renogram might be an useful method for the evaluation of renal function in E.H. fever during its course.
