Cystitis 



Inflammation of the bladder may be catarrhal or 

 purulent. Neither type has been extensively investi- 

 gated by the clinician, therefore the present knowledge 

 concerning them has been obtained by veterinarians at 

 abattoirs. 



Catarrhal Cystitis 



Catarrhal cystitis is not uncommon. In many 

 instances the condition is associated with cystic calculi, 

 but it may also be caused by infection. Occasionally 

 several cases of catarrhal cystitis may occur simultaneously 

 or successively in the same herd, and on obtaining the 

 history it is found that the affected swine have been fed 

 food stuff containing some, urinary irritant or they have 

 obtained quantities of turpentine or cantharides. Reten- 

 tion and fermentation of the urine predisposes to inflam- 

 mation of the cystic mucosa because of the liberation of 

 ammonia. 



Lesions. Catarrhal cystitis is characterized by the 

 following sequential lesions of the mucosa: hyperemia, 

 tumefaction, and coating of the surface with tenacious 

 mucus, desquamated epithelia, and pus cells. Later 

 there is desquamation of the surface epithelium, leaving 

 a denuded granulating surface. 



Symptoms. Frequent attempts at urination in 

 which small quantities of a turbid urine is eliminated 

 are symptoms of catarrhal cystitis. There may be a 

 straddling gait. 



Treatment. Remove the cause. The bladder in 

 females may be cleansed by a weak solution of corrosive 

 sublimate or creolin, and urinary sedatives should be 

 administered. Internal treatment is practically all that 

 can be given in male animals affected with cystitis. 



Purulent Cystitis 



Purulent cystitis is an inflammation of the urinary 

 bladder accompanied by the formation of pus. This 

 condition is not so common in swine as catarrhal cystitis.
