25. AMPUTATION OF THE PENIS. 

 XIV. 



Instruments. Scalpel, elastic ligature, strong silk 

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

 sion forceps. 



Technic. The operation is carried out on the recumbent 

 animal under complete anaesthesia, the upper hind foot be- 

 ing drawn forward 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 cavernosum to the ischium. If 

 possible amputate in front of the preputial ring. After the 

 penis is drawn out, and the preputial region is carefully 

 cleansed with brush and soap, an assistant grasps it just be- 

 hind the preputial ring with the hand and holds it firmly. 

 A temporary elastic ligature, p, is then applied in front of the 

 hand around the penis, or the piece of tape is looped around 

 it above the hand and it is made to serve both as a tour- 

 niquet and as a means for holding the penis, and it is then 

 excised by a circular incision about 5 cm. in front of the 

 elastic ligature, or immediately in front of the preputial 

 ring. The dorsal blood vessels of the penis are ligated sep- 

 arately. The urethra, u, lying on the ventral side of the 

 penis, covered by the corpus cavernosum of the urethra, is 

 dissected out of the urethral groove for a distance of about 

 2 cm., its dorsal wall slit and the mucous membrane sutured, 

 spread out fan-like to the surrounding tissues. The urethra 

 can also be slit dorsally and ventrally and the halves sutured 

 to the left and the right. A silk ligature, //, is applied to the 

 corpus cavernosum, c, just above the point of excision of the 

 penis and the elastic ligature then removed. After a few 

 days the silk ligature is also removed.
