[Experimental model of heterotopic renal transplantation in rat]

This study describes the experience with a new technique for heterotopic kidney transplantation in the laboratory rat. This technique combines already known aspects in renal experimental transplantation, with technical improvements added to each surgical step. Ten heterotopic kidney transplantation were performed. Immediate postoperative survival was 100% and at 48 hours was 90%. The patency of the vascular anastomosis checked at 72 hours in survivors was 100%. As a preliminary study, 20 renal hilum dissections were done, noting the topographical aspects of the renal vessels. Representing a standardized and easy to use model, this solid organ transplantation technique is a valuable tool for studying the immunological and physiopathological aspects of transplantation and for refining the microsurgical skills.
