オデルカ・ミラーカメラによる尿路撮影法

Abstract

ODELCA mirror camera is known to give an excellent picture on 70 x 70 mm size film as on a large film, therefore, a serial X-ray taking can be made in an inexpensive way. With use of it, we took several kinds of angiography and urography in or d er to establish functional X-ray diagnosis. (1) Translumbar abdom inal aortography was performed in 3 cases with renal tumor. Irregular pooling picture of contrast medium peculiar in the neoplastic area appeared 0.51.5 sec. later than the shadow of the renal artery and disappeared 1.0-4.5 sec. later than the latter. In a case of hydronephrosis, an aberrant artery- obstructing the right ureter appeared 1.0 second later and disappeared 2/3 sec. later than renal arteriogram. We should like to emphasize a clinical value of serial X-ray takin g in aortography. (2) Transfemoral Vena Cava phlebography was demonstrated by mea n s of ODELCA camera in which Maluf and McCoy's method was used. (3) According to Morales and Romanus' me t h od, urethrocystography was performed with semisolid contrast medium. Pictures were taken at the time of injecting contrast medium, contracting the pelvic floor and voiding, so that the motility of the male urethra might be observed in a realistic way. (4) According to Waterhouse's method, voiding urethrography was performed on a few patients. Posterior urethra and the vesical neck were shown in a case with cord bladder and another which had prostatectomy. (5) Seminal vesiculo g raphy was also studied in a serial way, and the seminal vesicles as well as de Graaf's phenomenon were radiologically observed and demonstrated.
