Murphy and Best,1in 1957, reviewed the literature concerning partial nephrectomy. In their concise and useful paper they recommended simple guillotine amputation and presented convincing evidence that the least damage is done to the kidney with this technique. They described hemostasis as secured during the resection by placement of a Crafoord clamp on the vascular pedicle. One of us (W. E. G.) has previously reported use of a small bulldog clamp placed on the renal artery alone during biopsy or partial nephrectomy.2Recently, we have had occasion to use a different technique for hemostasis during partial resection and have found it simple and effective. The kidney is well mobilized, allowing access to all of its surfaces. The area to be resected is identified, and the renal capsule is stripped from the area which is to be removed. At a point on the normal kidney, below the area of
