A Study for the Radiologic Diagnosis of the Seminal Vesicles

Lee, Yong Ha

Abstract

Since the first description on the vasoseminal vesiculography by Belfield(1913). Young and Waters (1920) had succeeded in getting the seminal vesiculograms by the routes of the ejaculatory ducts. Despite of the useful value of the seminal vesiculograms in the diagnosis of seminal vesiculopathies. it had not been used popularly due to difficulties on procedure. For evaluation of normal values of the seminal vesiculograms in Korean. 30 patients were selected. 20 patients of infertility and 10 patients of volunteers who received vasectomy. in Busan Armed Forces General Hospital from 1973 to 1975. The seminal vesiculograms had been taken by the vasectomy wounds in all cases. The results of analysis for normal seminal vesiculograms. in 15 cases, abnormal in 12 cases, and failed due to vas deference obstruction in 3 cases were as follows: 1. The length of main channel, in normal group, was 3.4+/-0.50cm, in right side. 3.3+/-0.12cm. in left side. and right side was 0.1cm longer than left. But in abnormal group it was 0.3 cm. shorter than normal group. 2. The width of lumen. in normal group. was 1.5+/-0.30cm. in right side. 1.3+/-0.34cm. in left side. and right side was 0.2cm. wider than left side. But in abnormal group it was 0.1cm. wider than normal group. 3. The angle between two long axes. in normal group, was 115+/-11. But in abnormal group it was 16 larger than normal group. 4. The ejaculatory duct, in normal group, runs directly downward to the verumontanum from the joined point of the seminal vesicle duct and the ampulla of vas. But in abnormal group it was obstructed or spastic in its contour.
