Urological applications of computerized axial tomography

B H Stewart, R A Straffon, J Haaga

    Transactions of the American Association of Genito-Urinary Surgeons
    |January 1, 1978
    PubMed
    Summary

    Computerized tomography (CT scanning) is a safe and effective diagnostic tool for genitourinary and retroperitoneal disorders. CT scanning accurately detects lesions and metastases, aiding in treatment selection and patient monitoring.

    Area of Science:

    • Radiology
    • Medical Imaging
    • Diagnostic Techniques

    Background:

    • Computerized tomography (CT) has been utilized for over four decades in diagnosing various medical conditions.
    • Over 7,200 patients have undergone CT scans, with a subset of 250 diagnosed with genitourinary system and retroperitoneum disorders.

    Purpose of the Study:

    • To evaluate the safety and efficacy of CT scanning in diagnosing genitourinary and retroperitoneal disorders.
    • To highlight the advantages of CT scanning over conventional diagnostic methods.

    Main Methods:

    • Analysis of experience with over 7,200 CT scans performed since 1974.
    • Focus on 250 patients with histologically proven genitourinary and retroperitoneal disorders.

    Main Results:

    • CT scanning demonstrates high accuracy in determining the characteristics of adrenal and renal mass lesions.
    • CT effectively identifies retroperitoneal, liver, and chest metastases, often when other tests yield negative results.
    • CT-guided needle placement for biopsies, aspirations, and drainage procedures is accurate.
    • Air contrast CT scanning aids in staging bladder tumors, particularly in obese patients.

    Conclusions:

    • CT scanning is a safe, effective, and advantageous diagnostic technique for genitourinary and retroperitoneal conditions.
    • CT scanning facilitates accurate lesion characterization, metastasis detection, and image-guided interventions.
    • CT scanning is valuable for monitoring disease progression during and after therapy due to its non-invasive nature and low radiation exposure.
    • CT scanning supports more judicious selection of invasive diagnostic procedures.
