STKANGUARY FROM CONCRETIONS 113 



The straining will stop as soon as the ''kinks" 

 straighten out. 



Tonics are to be given as after-treatment, and al- 

 icays a prophylactic dose of mixed bacterius to fore- 

 stall infection. The treatment of various complica- 

 tions or sequelae is left to the professional judgment 

 of the attending veterinarian. 



STRANGUARY FROM CONCRETIONS IN THE 

 SUB-URETHRAL DIVERTICULUM 



This is a condition which occurs in cows of mod- 

 erate and old age and may become evident in some 

 cases within a month or two after a difficult parturi- 

 tion. The latter form is probably the result of uterine 

 discharges or debris, such as hair, being forced into 

 the diverticulum during the difficult labor and acting 

 as an excitant to its lining membrane. The resulting 

 catarrhal excretions collect around the debris as a 

 nucleus, forming sometimes in the course of two 

 months, a concrete mass of the size of a hen ^g^. 



In other instances the concretion may be due to 

 the collection and inspissation of catarrhal discharges 

 from no particular cause. 



These concretions have the appearance of and are of 

 nearly the consistency of coffee grounds. Here and 

 there in the mass can be seen white flakes which are 

 somewhat firmer than the other portions. 



The elaboration and retention of concretions in the 

 suburethral diverticulum produces no objective symp- 

 toms until the mass has attained sufficient dimension 

 to interfere with the exit of urine from the urethra. 

 When this stage has been reached the cow does not 

 urinate quite as freely as she should; she requires a
