The symptoms are great pai:i on pressure over the region of the bladder; the urine passed is scant in quantity but at frequent intervals, and evidently with great pain. It frequently comes from a blow but is also produced by long exposure to cold or wet, and often the result of giving too much cantharides and turpentine. Sometimes due to stricture of the urethra (urinary passage) or calculi (stone). The treatment consists of first giving a brisk purgative, and should this not act it should be assisted by clysters of luke-warm water or thin gruel, or a hot bath. The acute symptoms having passed, give 3 gr. to 5 gr. of benzoic acid in pill form three times a day. If the urine is not freely passed the catheter should be used in the manner detailed under heading of Paralysis of the Bladder.
