A cyst is a closed pouch or sac filled with air or liquid. Simple kidney
cysts are usually small round sacs that have a thin wall and are filled with a
watery fluid. As people get older, cysts can form on the surface or in the
nephrons of the kidneys. They can range in size from a small pea to as large as
a grapefruit. Cysts can also grow over time.
Kidney cysts are almost always benign (not cancerous). Usually, the cysts don't cause any problems. In fact, people can go through life without even knowing that they have them.
In most cases, simple kidney cysts do not need to be treated. However, if a cyst is putting too much pressure on another organ or is affecting the way a kidney works, it might be necessary to shrink or remove the cyst. There are two procedures that are most commonly used to treat simple kidney cysts:
Aspiration and sclerotherapy — The doctor inserts a long needle under the skin to puncture the cyst and drain the fluid. A strong solution is then injected into the cyst to shrink it. This procedure can be repeated, if necessary.
Surgery — Surgery to remove a cyst can usually be done laparoscopically, using thin instruments inserted through small holes in the abdomen. During surgery, the doctor first drains the cyst and then cuts or burns away the cyst itself.
When a kidney does not work and needs to be removed, minimally invasive surgery with laparoscopy is available for you at the Urology Academic Practice.
Three little incisions are made into the abdomen to allow small surgical instruments to enter the abdomen. The kidney is freed inside the abdomen and removed through one of the incisions in the skin. This procedure usually requires an overnight stay in the hospital.
