ABSTRACT
During examination of kidney function under cisplastin chemotherapy in oncologic patients the nephrotoxicity of the drug have been shown during 24 hours after administration. We found that in 24 hours after injection ofcisplastin in the dose 50 mg/m2 of the surface of the body, the excretion of creatinine, sodium, potassium, osmotic active compounds and chlorides is increased more than two times, indicating for disorder in osmolality, volume and ionic regulation of kidney function. The determined peculiarities are consequences of kidney injuries, which are confirmed by an increase in erythrocyte- and leucocyteuria. We showed that alterations in homeostatic kidney function is due to damage of renal tubules. Our study necessitates a need for renal protection during the whole period of cisplastin chemotherapy.
