前立腺疾患の精管精嚢腺射精管造影像に対する検討

抄録

Sixty-six patients admitted to our clinic with hypertrophy, cancer, lithiasis and inflammation of the prostate and urinary bladder cancer were examined with special reference to vasoseminal vesiculography from July, 1962 to December, 1963. The prostatic carcinoma pattern by criteria of Vestby was most commonly seen in prostatic cancer and hypertrophy pattern in prostatic hypertophy. These patterns were not specific in the two lesions but were often seen in lithiasis and chronic inflammation of the prostate. A typical characteristic carcinoma pattern was observed in a case of cancer of the urinary bladder. The vasoseminal vesiculography gave us indispensable clues to estimate the extent of the malignant infiltration, when it showed the carcinoma pattern, such as stenosis of the ejaculatory ducts and seminal glands with irregular outline, although they appeared in malignancy of the surrounding organs. The hypertrophy pattern, especially distention of seminal glands was seen in several cases of cancer of the prostate.
