Perirenal pseudocysts are usually not life-threatening and some dogs need no treatment whatsoever. Otherwise, the fluid is surgically drained from the capsule, especially when the dog's abdomen is distended. There are also forms of treatment when severe renal diseases are involved.
Regular follow-up examinations (every two to six months) are required to evaluate the progression of the disease and the effectiveness of the treatment. Watch your dog for untoward symptoms, such as increased thirst (polydipsia), blood in urine (hematuria), and weight loss, and inform your veterinarian of them immediately, as they may be signs of renal failure.
