Technetium-99m glucoheptonate renal scan in diagnosis of acute renal injury.

Twenty-four patients with suspected renal injury were evaluated using high-dose intravenous pyelography, technetium-99m glucoheptonate radionuclide studies (RNS), and selective renal arteriography. Critical examination of these three diagnostic modalities reveal that RNS are extremely accurate in renal trauma evaluation and are more sensitive than intravenous pyelography. When RNS are used in conjunction with high-dose intravenous pyelography in the third workup for renal trauma, 60 to 65 per cent of diagnostic angiograms may be avoided.
