Spasm of the cervix vesicæ has been doubted, save as the result of local
inflammation, yet it not uncommonly takes place in horses and other
animals in connection with irritation attendant on the retention of
urine during work, or in dogs during a period passed indoors. Trouble
and suffering continues, with ineffectual efforts to micturate, but
practically complete relief is secured by catheterization or by a
spontaneous abundant discharge. The neurosis which leads to it is
produced or aggravated at times by enlarged prostate, or lesions in the
urethra. Intense fear may cause it.
_Treatment._ Remove cause. Give antispasmodics, valerian, musk,
bromides, chloral hydrate, opium, stramonium, hyoscyamus, codeine, etc.,
may be given as injections or suppositories. For the horse spread the
litter and soothe by whistle or song. Or use the catheter and correct
any local irritation.
