The advantage of small renal cyst puncture treatment is that it is less traumatic, the disadvantage is that it will recur. Small renal cyst puncture treatment is simple, less traumatic, low surgical risk, suitable for patients with cysts who are older, in poor physical condition, not able to tolerate laparoscopic surgery, or patients with renal cysts combined with more serious infections. However, patients with small renal cysts have puncture aspiration just from the fluid from the cyst, and the cyst wall has not disappeared, so it is still able to secrete fluid. Even if alcohol sclerosing agent is injected into the cyst, if the destruction of the cyst wall by alcohol is incomplete, the cyst wall will regenerate and it will be easy to cause recurrence. If you have a kidney cyst, you need to consult a doctor in time, and the treatment should be determined by the doctor according to the test results, do not make your own decisions.
