前立腺癌の診断における精管精嚢腺造影法の検討

Abstract

Vasoseminal vesiculography was performed in 112 patients with prostatic tumor (prostatic cancer 28 cases, prostatic hypertrophy 84 cases) in order to evaluate the individual characteristic findings for differential diagnosis of these diseases. 1) Vasoseminal vesiculography is a valuable examination which must be performed for differential diagnosis of the benign and malignant prostatic tumor, because it is valuable as rectal examination. 2) In some cases, vasoseminal vesiculography was a most useful diagnostic tool in detecting the early phase of prostatic cancer. 3) An early characteristic findings of prostatic cancer in this examination were observed as the disappearing of circular folds, narrowing and rigid contour of ejaculatory ducts. 4) The findings of contiguous part, especially, irregular sign or filling defect of the seminal vesicles are useful to know the stage of cancer.
