A cyst is a lump that is formed as a result of accumulation of fluids. Cysts in the kidney are common in patients who are aged 50 and above. Normally they cause little or no problem at all, but they might increase in size and compress the rest of the kidney parts. This leads to severe pain and increased blood pressure. The prime most method in treatment of cysts is to determine whether it is the actual cause for the pain and draining it while patient is under local anesthesia. Occasionally chemicals like sclerosant are injected not the cyst which prevents it from reforming. In cases where the cyst continues to refill after being treated initially and cause pains it has to be dealt surgically.
In traditional surgery, the kidneys can be approached through a large single incision below the abdomen and the healing time is much longer. In case of laparoscopic surgery, four small incisions are made near the rib cage. Prior to any kidney surgery the patient must not eat or drink anything. The patient is given general anesthetic or in certain cases an epidural one in order to reduce post operative pain. A dissecting balloon is inserted through the incisions to create a space for easy maneuvering of the laparoscope and the surgical instruments. CO2 gas used to distend the abdomen considerably reduces bleeding while surgery. At times ultrasonography is used to pinpoint the exact location of the cyst. The cyst is then aspirated followed by the excising or removal of cyst wall. The incisions are sutured later.
The [post operative discomforts and inconveniences can be controlled by the pain killers prescribed by the doctor. Hospital stay is short and normal activities can be resumed the same day itself. Although there is minimal pain and no serious wound to heal etc, this is major surgery, hence any kind of physical exertions are to be avoided.
