DISEASES OF THE KIDNEYS AND BLADDER. 387 



792. Injlammation <'j the Bladder, or Cystitis. 



Inllaiiiuiiition of the Bladder itst-lf is vciy bcldom met with. When it 

 occurs, it is generally eousccutivc on irritation of that organ, or it may bo 

 induced by sympathy with inflammatiou existing in the kidneys. 



793. Symjptoms. 



Inflammation of the Bladder i:5 indicated by the same symptoms as 

 irritation of that organ, but they appear in an aggravated degi'ce. Con- 

 siderable fever is present, indicated by a quickened pulse, injected visible 

 nmcous membrane, and a high teJiiperature. There is restlessness with 

 arching of the Imck, whisking of the tail, fre<juent straining, and a pro- 

 truded penis. At short intervals a few drops of urine, which is generally 

 thick, high coloured, and mixed with roi)y mucus and pus, will be passed 

 with difficulty. In some instances, blood may even be voided. In pro- 

 tracted cases the skin of the neighbouring j)arts becomes scalded by the 

 continued dribbling of the urine. Occasionally the anijiial lies down, as 

 if suffering from colic. If the hand be introduced into the rectum, the 

 bladder will be found shrivelled up and empty, and oftentimes hot and 

 tender ; and upon the apjilication of pressure to it, the patient will winco 

 and strain violently. During the voiding of the urine, some few dung 

 pellets may be passed. The skin is hot and dry, and the animal often 

 looks at his Hanks. 



If the disease is not relieved, the walls of the bladder will lose their 

 contractile power ; and in such cases the bladder may be found full, but 

 this would only occur in the last stage. The bladder may be ruptured 

 through over-distension. 



794. Treatment. 



The treatment in most respects is the same as that recommended for 

 nephritis. The case is quite as urgent, and eveiy precaution pointed out 

 in that disease should be adopted in this. 



The condition of the bladder should be ascei'tained at an early stage of 

 the disease. If much distended, gentle manipulation and pressure per 

 rectum may evacuate it, if there be no obstruction from calculus, or unless 

 the neck of the cyst is inflamed or spasmodically contracted. If this fails 

 the fluid must be evaluated by means of the catheter. If the disease be 

 due to the presence of calculi, nothing but an oi>eratiun jiromptly i>er- 

 formed can give relief. 



795. Infiammaiion of the Neck of the Bladder. 



Inflammation of the neck is more common than inflammation of the 

 body of the bladder. Its prominent symptom is retention of the urine 

 on account of the inflamed condition of the orifice through which it ought 

 to pass. Though the neck is principally concerned, yet the inflammation 

 ufl'ccts more or less the remainder of the organ. 



The treatment of the iniiammaton' attack is much the same as ha:^
