Renal Cysts Small, individual, isolated cysts in the kidneys will rarely cause problems. Disease develops when multiple cysts (polycystic) obliterate the functional kidney tissue. They will present with the usual signs of renal failure, thirst, excessive urination, vomiting, anorexia, weight loss and possibly oedema. Diagnosis can be confirmed by blood tests to show increased levels of urea and creatinine, and by visualisation of the cystic structures on X-ray or ultrasound scans. Treatment is with low protein diets and symptomatic drug therapy, the prognosis is poor. |
