Calculi of the seminal vesicles are occasionally found, usually atpost mortem. Often calculi give rise to no symptoms. Cases have beenreported, however, where the calculi have produced obstructive symp-toms—pain and seminal colic. These stones are, as a rule, soft, and theycan be crushed l^etween a sound introduced into the urethra and a fingerin the rectum. Tuberculosis of the seminal vesicles is the disease which mostfrequently brings these organs to the attention of the surgeon. It iscommonly found associated w^ith tuberculosis of the testicle, the diseasehaving extended to the vesicles from the testicle along the vas. Tuber-.

Primary tuberculosis of the seminalvesicles is not regarded as a probable lesion. In tuberculosis of theseminal vesicles the nodular thickening produced by the disease can befelt by rectal examination (Fig. 348). It has been found that in some cases tuberculosis of the seminal vesi-cles, secondary to tuberculosis of the testicles, goes on to cure after castra-tion has removed the primary focus. The operative removal of the seminal vesicles has not been verysuccessful and should not be undertaken unless it can be shown that thetuberculous lesion is limited to the vesicles and other structures, whichcan be removed. If an operation is decided upon, the Dittel-Zuckerkandlincision should be emplo
