510 URINARY APPARATUS. 



plugs with a catheter or in some other way. Such intervention is 

 very deHcate and difficult in the case of young animals. Sometimes it 

 is better to allow the discharge of urine from the umbilicus to continue, 

 and to recommend that the animal should be rapidly fattened for the 

 butcher. 



In practice, pervious urachus may be treated by suturing, by firing 

 across the fistula, and sometimes by blistering. The first step in all 

 cases is to see that the urethral passage is free. English veterinary 

 surgeons claim to have had a fair measure of success from these 

 methods. 



If a radical cure were . thought desirable, the abdomen would have 

 to be opened, and the operator would proceed to isolate the urachus, 

 resect it, and suture the base of the bladder by bringing together its 

 external surfaces. The operation, though not perhaps impossible, is 

 of no practical value.
