Extirpation of both kidneys from a cat and transplantation of 

 both kidneys from another cat, with exhibition 

 of specimens. 



By ALEXIS CARREL. 



\From the Rockefeller Institute for Medical Research^ 

 Both kidneys from a cat were extirpated and immediately 

 replaced by both kidneys from another cat. 



After this operation the animal urinated abundantly. Urine 

 collected during the first few days contained albumin. On the 

 fourteenth day, the cat was operated on for hernia of the small 

 intestine through the abdominal wound. The animal died from 

 general peritonitis one day after this second operation. 



The anatomical specimen shows that the kidneys are a little 

 enlarged. There is a slight hydronephrosis on the left side. 

 Nevertheless, both organs appear to be in good condition.
