사정관의 국소해부와 그 변이

Abstract

Although the importance of the ejaculatory duct as a direct communication between the testicular system and the urethra, insufficient investigation has been done about its detailed structure. Moreover, no report on Koreans is avaiable. Seventy enblocs cousisting of bladder, prostate, and ejaculatory duct in Korean adult males without gross signs of genito-urinary disorders were collected from autopsy cases. In forty materials, the contrast media was injected into the ejacultory duct through the ductus deferens and the vesculogram was taken, the confluence of the excretory duct and ductus deferens in forming the ejaculatory duct were classified, the ejaculatory duct's course and change of diameter observed, and the angle of the ejaculatory duct with its surrounding structure was measured in the AP and lateral view. And the diameter of another thirty cross sectioned ejaculatory ducts filled with microfill were measured in the same materials. The results were as follows : 1. When the ampulla and the duct of seminal vesicle was joined to form the ejaculatory duct, Type Ⅰ with a Y-shaped confluence of the two ducts was the most common (50.5%). 2. The angle of the mid-portion of the ejaculatory duct averaged 135。 in the right and 143。 in the left. 3. The diameter of the ejaculatory duct decreased from the proximal to the distal part ; the proximal diameter averaged 2.3mm and the distal 1.2mm.
