Simultaneous allotransplantation of kidney and spleen in dogs with or without previous splenectomy.

29 simultaneous kidney and spleen transplantations have been performed on dogs. Time of rejection, similar for both organs, occurs in a delay very close to the control series. No statistically difference of the day of rejection was observed in relation with the implantation of the spleen either on the iliac or on the mesenteric vessels. Splenectomy few weeks prior to transplantation had no effect on the day and the histological type of rejection of both transplanted organs.
