RENAL ANGIOGRAPHY IN UROLOGY

Percutaneous transfemoral catheterization is a first choice for renal angiography in urology. A modification of procedure for safe and reliable arterial puncture was described. Damages to arterial wall were avoided using a modified catheterization technique with a catheter fitted to thin guide wire. There were no serious complications by contrast medium in this series. Various angiograms of renal diseases were demonstrated with some case reports from 104 experiences. Renal angiography is of unquestionable superior value to differentiate renal tumor from other urological diseases. Especially, non-visualizing kidney is only diagnosed by renal angiography. Urological diagnosis became more accurate following the introduction of renal angiography. Part I. General Consideration of Renal Angiography Recently, the clinical application of angiography has been widely used with the development of catheterization technique, and the improvement in radiographic equipment; namely, the image intensifier, television monitoring, high speed film changers, and the development of less toxic contrast media. Renal angiography has been accepted in urology as a diagnostic method that correctly diagnose renovascular diseases, renal parenchymal lesions, and destructions of upper urinary tracts. The purpose of this paper is to investigate the safest method of the several arteriographic techniques and to emphasize the usefulness of renal arteriographic procedure in urological diagnosis. ADVANCES IN RENAL ANGIOGRAPHY R. Dos Santos and his co-workers introduced translumbar aortography in 1929. They could first demonstrated the renal vessels rentogenologically. Although this method had been used frequently for many years, its use has been declining in recent years because of its relatively high mortality rate. Retrograde aortography was introduced by Ichikawa in 1938, and Farinas in 1941 11 • In case of operative procedures, by Ichikawa, which is now being used in J a pen, is safer and gives distinct pictures of aorta and its branches.
