Evaluation of differential renal function studies in segmental renal artery occlusion.
3 patients with suspected renal segmental ischaemia are presented. In 2 of them segmental renal artery stenosis was demonstrated radiographically and the differential renal function studies predicted the outcome of surgery accurately. In the last patient no segmental renal artery stenosis was demonstrated on angiography, and surgery did not benefit this patient in spite of positive differential renal function studies for "curable" renal segmental ischaemia. Some haemodynamic aspects, as expressed by the differential renal function studies, are discussed.
