CHRONIC CATARRHAL CYSTITIS. 



This ma}^ begin as such or it may continue after an acute at- 

 tack. It has been noticed in horse, ox, and dog. 



It may be associated with calculi, gravel, papilloma, and bac- 

 terial invasion especially by the colon bacillus. 



Lesions. The mucosa and muscular coat are thickened, corru- 

 gated, puckered and contracted so that the bladder will not con- 

 tain more than a few ounces of urine. The surface of the mucosa 

 is discolored, mottled and variegated, slaty blue, brown, red, 

 purple, or even black, with ulcers, encrustations of triple phos- 

 phate, and fungoid elevations. In dogs especially, the prostate 

 is often enlarged. 



Symptoms. Frequent urination accomplished with pain, groan- 

 ing, or whining and it may be with sudden arrest. There may 

 be incontinence, the urine dribbling almost continuously from 

 the penis or vulva and in the latter case trickling down the thighs. 

 The presence of pus and mucus tends to mat the hairs, and a 

 strong urinous and ammoniacal odor is emitted. 



Palpation of the prepubian region often, and of the vagina or 

 rectum always causes pain and wincing. Temperature is normal. 



Urine is albuminous in ratio to the amount of pus, or above 

 that, and is then suggestive of kidney disease and likely to be 

 complicated by casts. 



Complicating lesions of the womb, vagina, prostate, and kid- 

 ney are to be carefully looked for, also cystic papilloma. 



Prognosis. Recovery though not uncommon is too often but 

 partial and it is usually desirable to fatten the animal. 



Treatment. Rest, moderate laxative diet, pure drinking water 

 ad libitum, warmth, antiseptic irrigation.
