Ligation and division of the left renal vein is a reasonable safe procedure in selected patients when exposure of the perirenal aorta is crucial. This manipulation is possible because of extensive venous collateralization from the left kidney in man. Measurement of the venous stump pressure before ligation is recommended to assess the degree of collateralization, and the upper limit within which the vein may be divided safely is probably in the neighborhood of 60 cm of water. Reanastomosis of the vein is not necessary for preservation of renal function, although transient left renal dysfunction may occur. Examination of the urine and careful monitoring of renal function should be routine in the postoperative period. Intravenous urography and left spermatic venography later in the postoperative course can indicate the ultimate degree of function of the left kidney and the pathways of venous collateralization. Preservation of normal function and venous architecture at the renal hilum should be the rule.
