Bilateral kidney cysts usually do not affect life expectancy. Untimely treatment may cause high blood pressure or ureteral obstruction. Patients with renal cysts are advised to go to the hospital as soon as possible and actively cooperate with doctors for treatment. Bilateral renal cysts can be drained of cystic fluid through renal cyst puncture, and sclerosing agents such as anhydrous ethanol can also be injected to prevent recurrence. Kidney cysts with large diameter can be treated by surgical removal of the cysts. Most of the patients do not affect the kidney function after active treatment, and the prognosis is generally good, basically will not affect the life expectancy. Some patients may recur after treatment. Long-term untreated renal cysts will cause metabolic abnormalities in the kidneys, which may lead to high blood pressure, and ureteral obstruction after compression of the ureter by the renal cysts. It is recommended that patients with double kidney cysts choose the appropriate treatment plan under the guidance of the doctor, and also need regular review after treatment to prevent the recurrence of the cysts.
