574 OPEEATIONS ON THE GENITO-UEINABY 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 applied 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 skia 

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

 of the penis. 



We divide the cavernous body, carefuUy avoiding injury to the 

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

 its groove forward into the cavernous body (Figure 477a) for a

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

 the division across the urethral canal completes the amputation. 

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

 us the stump of the cavernous body, almost dry, the hemorrhage 

 being prevented by the upper Ugature, which moreover, secures a 

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

 then slit on its iaf erior border on the median raphe and both flaps 

 turned upward and brought in contact by interrupted sutures with 

 the skin which has been so divided as to overlap the stump 

 (Fig. 4775). These sutures are made close to each other, of strong 

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

 at its lower margin a slit 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.
