How long does it take for a double kidney cyst to become uremic in general is mainly related to the type of cyst and treatment, and requires specific analysis of the problem. If the double kidney cysts are simple kidney cysts, the early cysts are small, most of them have no symptoms and do not need to be treated. If the cysts are larger, they only produce slight pressure on some kidneys and cause local back pain, back trapping and other symptoms, which usually do not cause kidney function damage and will not develop to uremia. If it is congenital polycystic kidney, it will eventually develop to the stage of uremic syndrome inexorably, but the specific time varies from person to person. In children, polycystic kidney can develop uremic syndrome very early, 20%-45% will progress to uremic syndrome before the patient is 15 years old; before the age of 25, 70% will enter the uremic stage. While the onset of polycystic kidney in adults is about after 30-40 weeks of age, its progression to uremia is relatively slow, and about 50% of patients over 60 years old will enter the uremic phase. Patients with double kidney cysts are recommended to go to the nephrology department of regular hospitals in time to be examined by professional doctors for symptomatic treatment after clear diagnosis. Once renal function impairment occurs, they should receive Chinese medicine treatment.
