PURPOSE: Evaluated the renal function of healthy dogs under two protocols for cisplatin administration. METHODS: All animals were under three chemotherapy sessions with cisplatin (60mg/m², i.v) at 21 days intervals. It was administerd, as fluid therapy, 0,9% sodium chloride solution (25mL/kg/hour, i.v), for two hours and, after cisplatin administration, for more one hour. The animals of the group 2 received furosemide (2mg/kg, i.v.) 20 minutes before the cisplatin administration. The renal function evaluation was made by physical examination, urinalisis, urea and creatinine serum levels, creatinine clearance, sodium and potassium fractional excretions, and urinary protein:creatinine ratio. The evaluations were done imidiatilly before, 1, 2, 5 and 21days after each one of the three chemotherapy sessions. RESULTS: All results were in the interval of normal variation, and no signs of renal damage or failure were detected. The animals that did not recive furosemide showed gradual increment of creatinine serum levels and decreases of the creatinine clearance. CONCLUSIONS: The protocol for fluid therapy seem to be effective in minimize the nephrotoxic action of cisplatin and an addition importante benefit is obtained with furosemide administration.
