The role of renal autotransplantation in complex urological reconstruction.

From 1972 to 1988, 108 patients underwent renal autotransplantation for renal artery disease (67), ureteral replacement (27), or renal cell carcinoma present bilaterally or in a solitary kidney (14). The most common indication for renal autotransplantation was to allow extracorporeal repair of complex branch renal artery lesions. Of the 54 patients in this group technically satisfactory branch renal arterial reconstruction and a successful clinical outcome were achieved in 52 (96%). Renal autotransplantation is the treatment of choice in these patients and also in selected children with main renal artery disease. Renal autotransplantation provided excellent results in 25 of 27 patients (92%) who required replacement of all or a major portion of the ureter. Over-all renal function was well preserved in these patients and only 1 has experienced chronic bacteriuria. Renal autotransplantation is a useful alternative to ileal interposition in this setting. Extracorporeal partial nephrectomy and renal autotransplantation were successful in 12 of 14 patients (85%) undergoing a nephron-sparing operation for renal cell carcinoma. In situ techniques are associated with less morbidity and currently are preferred in this group.
