How to treat renal cysts can be divided into different situations: first, most of the renal cysts refer to simple benign renal cysts, which are small in number and size, and grow slowly, so as not to cause significant impact on the kidney. So in the early days, there was no need for special treatment. Secondly, the size of the cyst continues to increase. When the color ultrasound indicates that the diameter of the renal cyst is more than five centimeters, we can consider doing kidney puncture, such as injecting sclerosing agent into the cyst, extracting fluid from the cyst and other methods to shrink the cyst. In addition, if the diameter is more than 10 cm, the cyst can be removed surgically. If the cyst ruptures and bleeds, you can use hemostatic drugs. If infection occurs after bleeding, you need to use antibiotics.
