OPERATIONS ON THE GENITAL ORGANS. 



Removal of Tumours from the Prepuce and Penis.— Tumours 

 are frequently found inside the prepuce and around the base 

 of the penis ; they are usually very vascular, bleeding upon the 

 slightest provocation. In stud dogs their presence is to be 

 regarded with great suspicion, as one variety, at all events 

 (sarcoma), is capable of being communicated to the bitch 

 during copulation, the vagina of the infected bitch again being 

 capable of infecting the penis of a healthy dog. The experi- 

 ments of Smith and Washbourni clearly demonstrate these 

 facts. 



Ordinary pedunculated tumours can be ligatured and readily 

 removed with scissors or actual cautery, but the infective 

 venereal tumours are exceedingly troublesome. If incom- 

 pletely removed the remains of the growth increase very 

 rapidly, and soon become larger than before. Smith and 

 VVashbourn obtained successful permanent results by snipping 

 the mucous membrane around the base of the tumour and 

 stripping it off with the attached growth from the underlying 

 tissues, the wound in the mucous membra.ne being drawn 

 together afterwards with fine silk. 



Paraphimosis.— In cases of paraphimosis it is sometimes 

 necessary, when all other means fail, to slit the extremity of 

 the prepuce. This is done with a fine blunt-pointed bistoury, 

 care being taken not to incise further than is absolutely
