Extracorporeal renal surgery and autotransplantation: indications, techniques and results.

Renal autotransplantation and/or an extracorporeal renal operation has been done 67 times in 65 patients. The indications for operation were severe ureteral injury in 8 patients, urinary undiversion in 2, renovascular hypertension in 10, carcinoma in a solitary kidney in 3, recurrent renal colic in 1 and donor arterial reconstruction before renal transplantation in 43. Methods of renal preservation and operative repair are described. Sixty-five operations were successful and 2 operations failed because of severe perirenal fibrosis in patients undergoing urinary undiversion. Renal autotransplantation and extracorporeal reconstruction can provide the best solution for selected urologic problems not correctable by conventional methods.
