AM PUT A 7 ION OF THE PENIS. 1 1 7 



In order to prevent injury to the rectum it should be emptied 

 of feces before the operation is undertaken. After the re- 

 moval of the stone, the operator may push the catheter 

 again over the ischial arch and unite the lips of the wound 

 in the urethral mucous membrane by means of intestinal 

 sutures. Flush the bladder and urethra by means of a 

 warm, 3 per cent, boric acid solution injected through the 

 catheter and then withdraw the latter. Finally, suture 

 the skin wound and insert a drainage tube or iodoform gauze 

 in the lower angle. 



Or the whole wound may be left entirely open and dressed 

 daily with antiseptics. In case the pelvic urethra has been 

 divided the suturing of the external wound is of questionable 

 utility. 



(For student practice on an anaesthetized horse, intro- 

 duce a stone into the bladder through the urethral wound 

 and practice grasping and removing it with the lithotomy 

 forceps. ) 



25. AMPUTATION OF THE PENIS. 

 Plate XIX and Fig. 12. 



Instruments. Scalpel, elastic ligature, strong silk 

 suture, strong piece of tape i m. long, artery and compres- 

 sion forceps. 



Technic. The operation is carried out on the recumbent 

 animal under local or general anaesthesia, the upper hind 

 foot being drawn backward or upward or otherwise so fixed 

 as to not obstruct the field of operation. The point of 

 operation is determined by the character of the disease and 

 the object to be attained. It may be made at any point 

 from the glans penis to the attachment of the corpus caver- 

 nosum to the ischium. If possible amputate in front of the 

 preputial ring.
