CHAPTER X. 

 DISEASES OF THE URINARY ORGANS. 



General Causes and Symptoms. Examination of the urine. Diuresis, Dia- 

 liciis Insipidus, Polyuria. Bloody urine, Haematuria. Simple inflammation 

 of the kidneys. Nephritis. Bright's disease. Desquamative Nephritis, Albu- 

 minuria, Albuminous urine. Spasm of the neck of the bladder. Paralysis of 

 the bladder. Inflammation of the bladder, Cystitis. Inflammation of the 

 Urethra, Gonorrhoea, Gleet. Stricture of the Urethra. Eversion of the 

 bladder. Urinary Calculi, and gravel. Stone in the kidney, ureter, bladder, 

 urethra, and prepuce, — in horses, cattle, sheep, pigs, and dogs. 



Diseases of the urinary organs are not infrequent in the 

 domestic animals, though less prevalent than in man. They 

 prevail above all in certain localities, as : on the magnesian 

 limestones, in company with goitre, on lands abounding in 

 diuretic or resinous plants or water, in damp regions where 

 fodder is secured in a wet, musty condition, where it is fed 

 covered with hoar-frost, or where frequent cold rains and winds 

 repress the perspiration and throw undue work on the kidneys. 

 Feeding to e.Kcess on aliments rich in phosphates of lime and 

 magnesia — bran, beans, peas, vetches, etc. — the habitual priva- 

 tion of water, injudicious dosing with diuretics, diseased heart 

 and lungs, which throws the blood back on the veins and 

 determines passive congestion of the kidneys, diseases of the 

 liver which, interfering with the oxidation of albuminoids, pre- 

 dispose to urinary deposit, and finally, mechanical injuries to 

 the loins or pelvis all tend to induce various urinary diseases. 



General Symptoms. — With most acute inflammations there is 

 a stiff straddling giit with the hind limbs, the loins are tender.
