Kidney Inflammation Due to Fluid Accumulation in Dogs

Perirenal Pseudocysts in Dogs

Perirenal pseudocysts are collections of fluid surrounding the kidneys, leading to their enlargement. Despite resembling cysts, they lack a genuine membrane covering. While uncommon in dogs, this condition can impact one or both kidneys.

Symptoms and Types

While the majority of dogs affected by a perirenal pseudocyst may exhibit an enlarged abdomen without pain, some may show no symptoms at all (asymptomatic). In more serious instances, indications of renal failure may become apparent.

Causes

While the majority of dogs affected by a perirenal pseudocyst may exhibit an enlarged abdomen without pain, some may show no symptoms at all (asymptomatic). In more serious instances, indications of renal failure may become apparent.

Diagnosis

You should provide your veterinarian with a detailed history of your dog’s health, including when symptoms began and their nature. The veterinarian will conduct a comprehensive physical examination, along with biochemistry profiling, urinalysis, and a complete blood count (CBC), which typically appear normal unless significant renal insufficiency is evident.

Imaging techniques such as X-rays and ultrasounds can help determine which kidney is affected. Furthermore, a fluid sample from around the affected kidney might be extracted for additional assessment.

Treatment

Perirenal pseudocysts typically pose no immediate danger, and some dogs may require no intervention at all. In cases where treatment is necessary, the fluid within the capsule is usually drained surgically, particularly if the dog’s abdomen is visibly distended. Alternative treatment options are available for cases involving severe renal diseases.

Living and Management

Regular follow-up appointments (typically every two to six months) are necessary to monitor the disease’s advancement and the treatment’s efficacy. Keep a close eye on your dog for any concerning symptoms, such as increased thirst (polydipsia), blood in the urine (hematuria), and weight loss, and promptly notify your veterinarian if any arise, as they could indicate renal failure.
