574 OPERATIONS ON THE GENITO-UEINAEY APPARATUS. 



of operation for the amputation of the penis. It differs from any 

 that have been previously recommended, and is as follows : 



The animal being prepared for the operation in the ordinary 

 way, the penis is secured with a ligature at its end and drawn 

 out of the sheath, and another ligature tightly appUed on the 

 upper part of the organ. An incision of the skin covering the 

 penis is made entirely around the organ and down to the cavern- 

 ous body, with the precaution of drawing the skin slightly back- 

 ward, so that when the amputation is completed, and the skin 

 allowed to return to its position, it will slightly overlap the stump 

 of the penis. 



We divide the cavernous body, carefully avoiding injury to the 

 urethra, and when this organ is reached it is dissected from 

 its groove forward into the cavernous body (Figure 4:77a) for a

length extending between one and one-half to two inches, when 

 the division across the urethral canal completes the amj)utation. 

 The removal of the diseased tissue being thus made, we have before 

 us the stump of the cavernous body, almost dry, the hemori'hage 

 being prevented by the upper Ugatm-e, which moreover, secures a 

 good hold and good view of the mutilated organ. The urethra is 

 then slit on its inferior border on the median raphe and both flajDS 

 turned upward and brought in contact by interrupted sutm-es with 

 the skin which has been so divided as to overlaj) the stump 

 (Fig. 477/^). These sutures are made close to each other, of strong 

 silk or catgut. The result is that the stump of the penis carries 

 at its lower margin a sHt of from one to one and one-half inches 

 in length, which, after allowing for all shrinkage of cicatricial 

 tissue, will always be sufficient to permit thorough micturition.
