It can be of two types depending on where the cyst is located, and how large it is in question:

  • Puncture and drainage of the cyst, and then filled with alcohol. On rare occasions, the doctor reduces the size of the cyst by inserting a long, thin needle into the skin to pierce the wall of the kidney cyst. Then drain the fluid from the cyst.
  • Surgery: Usually performed laparoscopically, using thin instruments that are inserted through small holes in the abdomen. During surgery, the doctor drains the cyst and then cuts or burns it. It is done very quickly, and we will only be in the hospital for a few days.
