DEBILITATED CONDITIONS OF THE BLADDER 195 



This consists in introducing the medicinal agents directl}'' into the bladder 

 by means of the catheter. The catheter is introduced into the bladder and 

 the bladder emptied, and by means of a small hose the catheter is con- 

 nected with a small funnel (see Fig. 82) , and a medicinal douche allowed to 

 flow into the bladder, and then the hose is placed in a dependent position and 

 the liquid allowed to trickle out. This can be repeated several times with- 

 out removing the catheter. When the animal is very small and a very 

 fine catheter is used, the fluid may not flow freely; in such a case a syringe 

 is adjusted to the end of the catheter and the fluid forced into the bladder 

 and again drawn out by means of the syringe, or an aspirator bottle 

 may be used. 



The writer first cleans out the bladder with clean water, then washes 

 with a solvition of boric acid, 2 per cent., or of tannin 2 per cent.; sulphate 

 of zinc 1 per cent., resorcin 1 per cent., nitrate of silver 1 to 2 percent. 

 Ginsiner recommends hydrargyrum oxycyanatum 1 to 100. Jahn had very 

 good results with adrenalin (suprarenin in 1 to 10,000) in hemorrhagic 

 cystitis. Pressnitz compresses or warm poultices to the hypogastric region, 

 and morphine or bromide of soda in cases where there is involuntary or 

 constant urination, also warm clysters to keep the intestines clear. 

 "Where there is extensive hemorrhage, give an injection of 2 per cent, solu- 

 tion of tannic acid. Creolin, 1 per cent., is also used, but is not as satis- 

 factory as the former. The liquids must be tepid. In the dog, of course, 

 this treatment is a little harder to perform than in the bitch, but with a 

 little practice it is very easily accomplished and produces very satisfac- 

 tory results. With the bitch a short metallic catheter can be used. It 

 must l^e remembered that house dogs must be allowed to go out fre- 

 quently as the retention of urine is a frequent cause of this condition. 



Debilitated or Paralytic Conditions of the Bladder. 

 Paralysis and Paresis. Vesical Uremia. 



Etiology, Clinical Symptoms, and Prognosis. — Weak bladders, due to 

 paralysis or paresis, are generally seen in old dogs, and are produced by a 

 number of causes. One frequent cause of this condition is that house dogs 

 that cannot get outside or are carried long distance on the trains, or are 

 benched at a show, retain the urine for a long time, producing extreme 

 distention of the bladder. Obstructions of various kinds which prevent 

 the passage of the urine, such as the presence of a calculus at the neck of the 

 bladder or in the urethra, as hypertrophy of the prostate, strictures of the 

 urethra, by weakness of the muscular coat of the bladder, caused by 

 chronic catarrh of that organ, and certain diseases of the nervous system 

 al.<o produce this condition.
