Fig. 129 — Retention of tlie Urine. 



ciilar contractions of the neck of tlie IjlacKlcr, l)}- enlargement of 

 the prostate gland, prolapse of the rectum, dirt in the sheath, or 

 cancer of the penis. 



Symptoms. — Frequent and ineffectual attempts to nrinate. 



The animal will stretch himself out, strain violently, and groan. 



He may succeed in voiding a very small quantity of nrine, which 



comes away in a short, 

 forcible jet. An ex- 

 amination per rectum 

 will find the bladder 

 full of urine. 



Treatment. 

 The arm should be well 

 lubricated and gently 

 passed into the rectum 

 until the bladedr is 

 reached. Gentle pressure should be brought to bear upon it and 

 its contents forced out. Should this fail to remove the urine, a 

 warm-water enema, especially an enema made from the decoc- 

 tion of tobacco, should be used; after which pressure may again 

 be employed to the bladder. If this fail the catheter must be 

 passed and the urine withdrawn. 



MELANOTIC DEPOSITS IN THE BLADDER. 



These are deposits seen in bladders of gray horses. Tumors 

 and fungoid growths are also found in the bladder. 



Symptoms. — A difficulty in voiding the urine; the urine is 

 tinged with blood, owing to rupture of small blood vessels. At 

 times the urine may be black. The animal falls off in condition. 

 The tumor may be detected by an examination per rectum. 



Treatment. — Not much can be done for these conditions. If 

 a fungoid growth is present, its removal may be tried. The 

 operation should not be tried unless it be the only means of 

 pve venting death.
