[Renal autotransplantation]

The progress of renal transplantation in the last 2 decades has made possible the development of autotransplantation and extracorporeal surgery of the kidney. By those techniques, it is possible to operate upon patients in which conservative conventional surgery is impossible. In this article the technique is described, and two typical cases are reported. The mean indications are renal vascular hypertension, malignant tumors of the kidney, traumatic lesions of the kidney and ureteral lesions. All these indications are described in detail.
