The quantity of mucus which passes off with the urine varies greatly at different periods and in different cases. In the early stages it may entirely escape notice, being so small that if the urine is not saved in a vessel and accumulated for the twenty-four hours the mucus can hardly be detected; thus, the entire quantity of the above period may often not exceed two teaspoonfuls. When the disease becomes more advanced, the quantity of mucus may be equal to the quantity of urine that passes. The secretion is very thick and sticky, and settles to the bottom of the vessel or adheres to its surface. If there is pus mixed with the mucous secretion, it becomes a more serious question, and it may then be inferred that other organs are involved, the conductors of urine from the kidneys to the bladder, for instance, or the kidneys themselves. If the disease is confined to the bladder, the prospects for a cure are very favorable; only when diseases of other organs in the neighborhood are the exciting causes of the malady are the chances for a cure correspondingly limited. The success of any treatment will depend in a great measure upon the nature of the exciting causes. These require to be removed, if within the possibility of medical skill, before the catarrh can be made to subside. Should the mucous or muco-purulent secretion be very abundant, the bladder must be thoroughly rinsed out; first once every twenty-four hours, and afterwards every other day, so that the mucous membrane will be cleansed from all foreign irritating elements. I am employing for this purpose Thiersche’s Boro-Salicylic solution. This of course can only be carried out by a skillful physician. When the disease is in its incipient stage it is amenable to intelligently-directed home treatment. The most perfect rest of mind and body is one of the essentials to success, the entire suspension of stimulating drinks of an alcoholic nature, of which beer is the most irritating, and tea or coffee must be discarded. A milk and vegetable diet is the most beneficial to subsist on, and all condiments, even salt, must be dispensed with. If the bowels are costive they must be regulated either by means of enemas of warm water, or what may prove of greater and more lasting benefit is the use of Femina laxative tablets. One tablet should be taken every night at bedtime, and if one operates too much, then one every other night may be all that is required. Demulcent drinks of flaxseed tea, or slippery-elm water, should be drunk freely, and for the catarrh of the bladder there is no prescription that ever gave me the same satisfactory results as this one:—— NO.
