Renal hypothermia in situ by venous passages: experimental work on dogs.

The paper presents the possibilities of achieving regional renal hypothermia by rinsing the kidney venous system with a cooling solution. The cooling solution flows in and out of the kidney venous system through a specially constructed catheter with two lumens while the kidney is deprived of its blood flow. This method of cooling the kidney proved to be successful in rapidly lowering the temperature. The level of plasma creatinine, histological examination of the material, renography and scintigraphy show that our technique of hypothermia is successful and can be easily performed.
