Ailments of the urinary system
Continued from last week
Kidney failure (uremic poisoning)
Kidney failure, also called renal failure, may be sudden and acute or chronic and progressive. Acute failure occurs as an after-effect of certain infectious diseases (such as leptospirosis) and during shock conditions and poisonings. Chronic kidney failure is the end result of a nephritis and possibly other long-standing diseases.
It is important that it be understood that the kidneys will not produce urine, if the dog’s blood pressure falls below a critical threshold. Accordingly, dehydration, blood loss, shock, congestive heart failure, and injuries to the arteries of the kidneys, all may cause acute renal failure. This may occur even though the kidneys are healthy and normal. This type of kidney failure is called pre-renal. It will improve if the underlying cause is treated promptly.
