DISEASES OF THE PEXIS AND PREPUCE 207 



condition where the penis passes through the narrow opening of the 

 prepuce the gLans becomes swollen, and the prepuce becomes tightened 

 behind the glans penis, the narrow ring of the prepuce causes venous 

 engorgement, becomes oedematous, causing a great swelling and purple 

 coloration of the glans, and if this is allowed to remain some time, causes 

 partial gangrene. The above phenomenon is seen during coitus or from 

 erection in attempting copulation, from traumatic causes, from neoforma- 

 tion, or paralysis of the penis. 



The therapeutics of paraphimosis consists in reducing the glans as 

 soon as possible with friction and careful manipulation; this is accom- 

 plished by careful lubrication of the parts with some bland oil and putting 

 a steady pressure on the glans, at the same time pressing forward the pre- 

 puce over the enlarged part; with a little patience it is reduced. If this 

 is not successful, bathe the glans with cold water or alum applications, 

 lead water, sulphate of zinc, or wrap the protruding portion of the penis 

 in a cold bandage, beginning at the outer end and quickly wrapping it 

 around the distended penis, thus forcing the blood out of the engorged 

 glans, then as the bandage is removed the penis is returned, drawing the 

 prepuce over it. If we do not reduce it by this means, then cut the ring 

 with a curved probe-pointed bistoury or a pair of scissors. It can then 

 be returned immediately; scarification of the penis is rarely necessary. 

 In extensive necrosis of the glans, paralysis, tumors, etc., it may be neces- 

 sary to remove the penis; this is removed by a circular sweep of the knife. 

 If the penal bone is to be cut through it may be done by means of a 

 pair of bone forceps or sawed through. To overcome stenosis of the 

 urethra from cicatricial contraction of the wound the urethra is opened 

 about 0.5 cm. and sewed back of the wall of the penis. It is well, how- 

 ever, not to resort to this until you have tried every other method. 



Gonorrhoea of the Prepuce. Preputial Catarrh. — By this term we 

 mean catarrhal or purulent inflammation of the mucous membrane of 

 the prepuce; it is rather common in dogs that are well fed; it is harmless 

 but unsightly from the discharge of yellow mucus constantly dripping 

 from the end of the prepuce, and some cases are extremely obstinate to 

 treat. It may be caused by retention of urine, phimosis, calculi of the 

 bladder, prolonged coitus, dirt, uncleanliness, or masturbation. It is 

 frequently observed in old dogs, due in their case to stagnation of the 

 veins of the prostate. The symptoms consist in slight redness, and 

 swelling of the prepuce and glans, and the secretion of a thin, purulent 

 mucus, which is generally licked off by the animal. On pushing back 

 the prepuce, the lymph-follicles are generally found to be swollen, 

 and can be felt on manipulation with the finger as small bodies about 

 size of a seed or pea. In rare cases the inner wall of the prepuce and the 

 bulbous portion of the glans are covered with papillary excrescences.
