There is no clinical method to eliminate renal cysts quickly, simple renal cysts less than 4 cm usually do not need treatment for the time being, renal cysts ≥ 4 cm need surgical treatment. Simple renal cysts less than 4 cm have little effect on renal function and surrounding tissues, and patients usually have no obvious symptoms, so they can be temporarily observed first, and usually review regularly to do a good job of prevention and avoid infection. If the patient’s renal cyst is larger in diameter, ≥4 cm or produces compression symptoms in the surrounding tissues, and causes urinary tract obstruction or rupture of the cyst, hemorrhage, co-infection, etc., then the patient needs to be treated with surgery, which can achieve better therapeutic effects. After surgery, patients should do a good job of daily care, which can lead to faster recovery. If the patient suffers from renal cysts, it is recommended to consult a doctor in time and actively treat under the guidance of the doctor.
