Kidney transplantation: the use of abnormal kidneys

We transplanted 6 anatomically abnormal kidneys: a horseshoe kidney that after division was transplanted into 2 recipients; 1 kidney with ureteral stones and hydronephrosis; 1 ectopic and 1 hydronephrotic kidney; 2 kidneys with extensive ureteric lesions, donated as free organs. All these kidneys ultimately had normal function in the recipients, long-term in 4.2 patients died but in neither was the death caused by the renal abnormality.
