658 PARALYSIS AND INJURIES OF THE PENIS. 



of long hairs around the prepuce, and il is often seen after coitus. 

 Should the hairs become adherent to the penis during erection, their 

 ends are apt to be afterwards drawn back into the prepuce. The 

 edge of the latter is rolled round its outer surface, is turned inwards, 

 and the further return of the penis prevented. The glans then begins 

 to swell, which, of course, aggravates matters. Swelling of the 

 glans from inflammation or new growths may also produce the 

 condition. Bang found a ribbon twisted round the penis of a dog ; 

 the parts were much swollen. 



The glans is exposed, and shows more or less cedematous swelling ; 

 its surface is shining, bright red, sometimes of a darker tint, often 

 covered with dirt and dust, and not infrequently dry. The prepuce 

 is tightly applied behind the swollen glans, strangulating it. When 

 the disease has existed for some time, the parts may be injured or 

 ulcerated. Haubner once had to remove the glans and os penis on 

 account of necrosis ; recovery followed in fourteen days. Apart 

 from those caused by malignant new growths about the glans or by 

 severe wounds to the penis the greater number of cases progress 

 favourably without very elaborate precautions. 



Prognosis depends on the nature of the disease. Paralysis of 

 the penis or of the retractor penis is generally incurable. Only those 

 forms occurring during infectious diseases disappear with the lapse 

 of time. The longer, therefore, the condition has existed, the less 

 the chance of recovery. Swelling of the prepuce is often very 

 obstinate, and old standing cases are most difficult of treatment. 

 Hard, firm swellings are less easy to get rid of than those which are 

 soft and cedematous. 



Treatment. In the dog after thoroughly cleansing the glans 

 and prepuce, the displaced hair must be withdrawn or cut off with 

 scissors. A few drops of oil can then be placed on the glans and 

 tense prepuce, the animal placed on its back, the prepuce grasped on 

 each side with the forefinger and thumb, and attempts made to draw 

 it over the glans. The attempt generally succeeds ; slight pressure 

 with the finger on the glans is sometimes of assistance. Failing 

 reposition in this way, the lower border of the prepuce may be laid 

 open, when the penis will return of itself. Any subsequent inflam- 

 mation is combated by bathing with solution of acetate of zinc, 

 alum, &c. ; this is, however, seldom necessary. 



Inflammation of the prepuce is to be treated as already described. 

 Should the outer coats of the sheath be already contracted, they 

 may be divided. Application of a suspensory bandage will assist 

 removal of oedema, and is also useful in swelling of the prepuce. The
