Kidney cysts are clinically divided into simple renal cysts, multiple renal cysts and polycystic kidneys. Among them, simple renal cysts are more common and most of them have no clinical symptoms, but when the cysts are larger, they can show discomfort and hidden or dull pain in the back, which usually do not affect daily life. The treatment of this disease depends on the size of the cyst, the location and the compression of the kidney. Generally, cysts smaller than 4-5 cm do not require treatment, but clinical observation and regular ultrasound review, no medication is needed and no medication can control their growth or reduce their size. When the cyst exceeds 4-5 cm, it needs to be treated. The treatment can be applied to kidney puncture intervention. This method is simple, less painful and less expensive; the disadvantage is that it can recur in some patients. In the past, open surgery was also used to remove the cyst wall. This method is effective in treatment, but it is more devastating and costly for the patient. It has been replaced by minimally invasive laparoscopy. Laparoscopy is the application of special endoscopic instruments to debulk and decompress the cyst via the abdominal or retroperitoneal space. The advantage is that it is less invasive with good results, and the disadvantage compared with renal puncture intervention is that it requires special instrumentation conditions and is costly (about 10,000 yuan).
