The aim of the present study is to describe and evaluate a new technique for performing Computed-Tomography Retrograde Urethrography (CT-RUG). Males with urethral anomalies detected by retrograde urethrography (RUG) and/or retrograde sonourethrography (RSUG) underwent CT-RUG using the clamp method and three radiologists evaluated the anomalies in each technique separately and blindly. CT-RUG was done successfully in all the cases (n = 22), with means of 6 min duration and 95 mL of contrast; no pain was reported by 81% of the patients (VAS: 0) and very mild pain by the rest (VAS: 0.5–1.2). CT-RUG showed better diagnostic efficacy in cases of periurethral fistula (n = 8), urethral stent (n = 3), previous urethroplasty and urethral lithiasis (n = 2), a similar accuracy to RSUG for measuring the length of anterior urethral strictures (n = 9) and greater accuracy than RUG (p = 0.008). Six cases received 2 CT sweeps, with an effective dose of 4.96 mSv, and the remaining 16 had 1 sweep and received 3.456 mSv. To the best of our knowledge, this is the first study to describe the clamp method for CT-RUG, a method that is effective and comfortable for both the patient and the operator (retrograde infusion of contrast).

Subdural Tapping

Abstract A new technique for the treatment of chronic subdural hematoma by tapping and irrigation was shown by computed tomography to be safe and reliable in 39 patients. The basis for such treatment is discussed in light of the current theories of the pathogenesis of chronic subdural hematoma.

Insight Into

An attempt is made briefly to outline the medical potentials of computed tomography. Examinations with this new and very promising X-ray technique are made without discomfort, pain or risks for the patient. The examination does not require highly trained personnel. It permits a number of pathological conditions to be reproduced directly in an image representing a transverse section of the body. Different soft tissues are visualized directly and the shape of internal organs can be accurately perceived. Opacifying media may be used to enhance the visibility of certain organs or tissues changed by pathological processes. Computed tomography might be used to make function tests of various organs where it will be possible to follow the function not only of the whole organ, but of each elementary volume of it. In radiation therapy, computed tomography offers a much higher precision in the planning of the radiation treatment of a tumour. From the tomogram a computer can readily find the optimal directions and intensities of the radiation in order to obtain the required effect on the tumour while sparing the healthy organs. This new technique will give us fresh insight into many common and serious disorders having unknown mechanisms and causes.
