Radiological examinations of the urinary tract. Changes during the last 24 years.
Procedures for imaging the urinary tract have been recorded in six Norwegian hospitals for the last 24 years. For three of the hospitals, data were collected from 1965 to 1989, and for the other three from 1966, 1971 and 1975, respectively. There was a significant reduction in the number of intravenous pyelograms, voiding cystograms, and renal angiograms, but the number of retrograde pyelograms and plain radiographs of the urinary tract remained constant. Computed tomography of the urinary tract increased during the first years, but after the introduction of ultrasonography, the number of computed tomograms decreased. Ultrasonographic examinations of the urinary tract are still rapidly increasing, and seem to have replaced some of the other imaging techniques. The present results should be taken into consideration when planning the health care for the future.
