New surgical approach to complicated renal anomalies.

The procedures of bench surgery and autotransplantation have been extended to cases of complicated renal anomalies since conventional techniques do not always correct the multiple problems present. Complicated renal anomalies require techniques that will result in the simultaneous treatment of the renal pathological condition and of the urinary tract. In other words, the kidney must have normal anatomical orientation, allowing for ample resection of the dysplastic or dystrophic tract, good urinary drainage and no loss of renal parenchyma. A combination of nephrectomy, bench surgery and autotransplantation has been used successfully in 8 of 9 patients with various anomalies.
