title: [The evaluation of split renal function in the experimentally induced transient renal vein obstruction].
abstract: The split renal function was measured in order to evaluate the alteration of renal function secondary from transient renal vein obstruction. Three microcuries of I-131 Hippuran and 7 microCi of Tc-99m DTPA were injected into the femoral vein of adult male rats 30 min, 3 hr, 6 hr, 2 days and 1 week after the renal vein obstruction for 30 min. Blood samples were taken from the tail vein 5, 10, 15, 20 and 30 min after injection. Immediately after taking blood sample at 30 min, both kidneys and urinary bladder with ureters were taken. The radioactivities of Tc-99m and I-131 of these samples were measured respectively using a well type scintillation counter at the energy ranges of 140 KeV +/- 25% and 360 KeV +/- 25%. In the obstructed side, the blood clearances of I-131 Hippuran (ERPF) and Tc-99m DTPA (GFR) were decreased at 30 min and 6 hr after the release of left renal vein obstruction. Therefore the filtration fraction was not significantly changed. In conclusion, the single study using either Tc-99m DTPA or I-131 Hippuran may be enough to evaluate the alteration of split renal function in a model of renal vein obstruction, although the combined study using both agents is more preferable.
