668 DISEASES OF THE SCROTUM. 



assistance in five days after operation. Removal of the enlarged 

 prostate has been attempted in the dog, but the results have not 

 been satisfactory. Probably enucleation of the gland substance, 

 taking care to lacerate the capsule as little as possible, may eventually 

 prove successful. 



R. H. Clarke operated on an eight year old bull dog, in which 

 the prostate had become enlarged to the size of a billiard ball, a 

 portion as large as a walnut being ossified. The symptoms con- 

 sisted chiefly in straining as if to pass faeces, and were only marked 

 for three months before death. Mr. Clarke purposed forming a 

 perineal fistula, but as the conditions appeared unfavourable when 

 operation was advanced, the dog was killed with chloroform. The 

 description of symptoms, treatment, and especially of the post- 

 mortem examination and miscroscopical appearances of the growth, 

 are fully given in Cadiot and Dollar's " Clinical Veterinary Medicine 

 and Surgery." 



VI.— DISEASES OF THE SCROTUM. 



(a) Afart from those caused by operative interference, injuries, 

 wounds and bruises are comparatively rare in animals, in conse- 

 quence of the sheltered position of the scrotum. In dogs, however, 

 the scrotum is sometimes bitten, and injuries may be caused in other 

 animals by fragments of glass and wood, and, during attempts to 

 jump hedges, by thorns. In horses the scrotum is sometimes injured 

 by the carriage-pole, and decubital necrosis readily occurs in dogs 

 after lying long in one position, as during paraplegia or distemper. 

 In delivering a prognosis, it should be particularly noted whether 

 or not the injuries are of a penetrating character, and have affected 

 the testicle. By penetrating wounds are meant those which extend 

 to the tunica vaginalis or peritoneal cavity. But even in penetrating 

 wounds the prognosis and chance of recovery are favourable, provided 

 there is no diffuse peritonitis, though the testicle can seldom be 

 saved, on account of the danger of infection extending to the peri- 

 toneum. Severe bruises and injuries followed by extensive necrosis 

 must be viewed as dangerous. Superficial wounds, on the other 

 hand, generally heal readily. 



Treatment. The parts are first thoroughly cleansed, and then 

 carefully examined, to determine the area of the injury. If the 

 testicle is to be saved, strict antiseptic treatment will be required. 

 In large animals the suspensory bandage already described should 

 be used. In deep wounds penetrating the tunica vaginalis, pus 

 formation and peritonitis are likely to ensue unless the parts are
