ABSTRACT
Four hundred and eighty-four serial renograms have been performed in 39 patients following renal transplantation.
Four distinctive renogram patterns have evolved from this study. Normal patterns immediately posttransplant were obtained in grafts from related donors and persistence of this pattern has been observed up to twenty-four months.
Determination of T
time in serial renogram tracings showing improvement or degeneration correlated well with conventional renal function studies.
Renograms showing continued prolongation of the T
time were characteristic of ultimate rejection.
Patterns suggestive of acute tubular necrosis, ureteral obstruction and arterial occlusion were of aid in the management of patients.
A delay in the T
time while not characteristic of rejection occurs early in the rejection phase, frequently precedes change in conventional renal studies, and is of value in predicting the need for additional immunosuppressive therapy.
