The treatment plan for calcified kidney cysts needs to be based on the size of the kidney cyst. If the kidney cyst is small and the kidney function is normal, regular urological ultrasound or urological CT can be done to observe the size of the cyst and the kidney function, and no special treatment is needed. Because any medicine cannot reduce the kidney cyst or eliminate the calcification, if the kidney cyst is calcified and the kidney cyst is larger than 4cm, if not treated in time, it may become malignant, bleeding, infection, rupture, compression causing hydronephrosis or abnormal kidney function, and at the same time, it is easy to cause lumbar soreness and discomfort, so the treatment of surgical decompression can be performed to reduce the damage of kidney function.
