  • Title: Urological applications of computerized axial tomography.
    Author: Stewart BH, Straffon RA, Haaga J, Seidelmann FE.
    Journal: Trans Am Assoc Genitourin Surg; 1978; 70():119-30. PubMed ID: 753012.
    Abstract:
    Computerized tomography (CT scanning) of the chest and abdomen has been used as a diagnostic technique in more than 7,200 patients since 1974, 250 of whom had histological proved disorders of the genitourinary system and retroperitoneum. On the basis of this experience CT scanning has been found to be safe and effective, and offers certain advantages over conventional techniques. The number, extent and content of adrenal and renal mass lesions can be determined with relatively great accuracy. The presence and extent of metastases into the retroperitoneum, liver and chest often can be shown by CT scanning when other tests are negative. Placement of needles for aspiration, biopsy, injection of contrast medium or insertion of drainage tubes can be done accurately under computerized tomographic control. Air contrast scanning of the bladder can be of real help in staging bladder tumors, espically in obese patients. Computerized tomography in itself is non-invasive, carries a low radiation exposure comparable to other radiographic procedures and therefore, can, be valuable in following the course of patients with various diseases during and after therapy. While CT scanning will not replace other diagnostic procedures it should lead to a more judicious selection of potentially hazardous tests, such as angiography, aspiration and open biopsy.
