Pathology of the urinary system

2) Extra-renal lesions in uremia (renal failure)

 

Present in various organs, particularly in dogs and cats; their occurrence is influenced by the specific 

nature (e.g. glomerular versus tubular damage) and rate of development of the renal lesions.

1. 

Uremic stomatitis / glossitis

  

        -  due to chemical injury of the oral mucosa when high urea in the blood permeates into the 

saliva; 

        -  oral bacteria transform urea into ammonia (NH

3

) → irritates oral epithelium → ulceration of 

the mucosa with adhered brown, foul-smelling mucoid material (halitosis / urine breath).
