RENAL NEOPLASMS 87 



Pyelitis 

 (Inflammation of the Pelvis of the Kidney) 



Cause. — Pyelitis is the usual result of an in- 

 fection spreading from the bladder to the kidney. 

 It also often develops in the course of infectious 

 diseases, and may be caused by irritant poisons and 

 renal calculi. The presence of the Strongylus giga-5 

 in the pelvis of the kidney may lead to pyelitis. 

 This, however, is of rare occurrence. 



Symptoms. — The manifestations of pyelitis are so 

 indefinite that we have to rely for its diagnosis 

 almost entirely upon a microscopical examination of 

 the urine. Pus, and the cells characteristic of the 

 epithelium of the pelvis, being found therein are 

 indicative of this condition. In addition we may 

 find coagulas of blood, necrotic mucous tissue, and if 

 Strongylus gigas is the exciting cause, ova of this 

 parasite. There is often difficulty in urination and 

 colicky attacks of pain. 



Treatment. — In addition to the treatment required 

 for the primary disease, antiseptics and astringents 

 should be administered. Of these formin (hexame- 

 thylenetetramin) is most effectual, exerting its 

 antiseptic action by the liberation of formic alde- 

 hyd along the whole urogenital tract. In chronic 

 cases buehu and juniper in doses of one to two 

 ounces may be given with benefit. For the pain, 

 give Cannabis indica in doses of from one to two 

 minims of the fluid extract. 



Degenerations and Tumors 



]|\[either of these conditions is of much interest, 

 from a clinical point of view, since in the dog their 

 diagnosis is most uncertain and treatrnent useless.
