腎・尿管のComputerized Tomography

Abstract

The application of computerized tomography (CT) GE CT/T X2 to the diagnosis of renal masses, stones, anomalies, tuberculosis and non or poorly functioning kidney due to various causes was described. CT was relatively rapid and easy, independent of renal function, and free of complications except for those which might arise when contrast media were used. This new imaging technique was most contributive to detect radiolucent renal stone and renal pelvic tumor because diagnosis of those lesions had been difficult by the other radiologic examinations. CT was also useful to decide operative procedures, e.g. nephrectomy or kidney preserving operation, in the case in which intravenous pyelography failed to reveal renal parenchymal condition. CT, the non-invasive technique, could obviate the need for arteriography in a number of renal anomalies, e.g. polycystic kidney, renal agenesis and horseshoe kidney, and was especially useful in the childhood. CT gave many valuable informations for the differential diagnosis of ureteral tumor from radiolucent renal stone and extraureteral mass lesion, although CT could not directly demonstrate the ureteral tumor.
