[Uric nephropathy in malignant hemopaties: three cases with conserved diuresis (author's transl)].

Three observations of acute hyperuricemic renal insufficiency with conserved diuresis appeared during the course of a citostatic treatment of a lymphoblastic acute leukemia and two lymphoblastic lymphosarcomas are studied. The evolution of nephropathy was favourable in all cases by means of allopurinol and fluidtherapy.
