None of the above', 'role': 'user'}, {'content': "Answer: A \nExplanation: Ans. is 'a' i.e., Iliac fossa * The transplant kidney is placed in the iliac fossa in the retroperitoneal position leaving the native kidneys in situ.* Using a retroperitoneal approach the donor renal vein is anastomosed end-to-side to the external iliac vein.* The donor renal artery on a Carrel patch of donor aorta is anastomosed end-to-side to the external iliac artery. If the donor renal artery lacks an aortic patch, as in the case of a living donor transplant, it may be preferable to anastomose the donor artery end-to-end to the recipient internal iliac artery.", 'role': 'assistant'}]
