Renal Cyst Surgery in Sharjah
Medically reviewed by Dar Al Kamal Team
What is renal cyst surgery?
Renal cyst surgery treats a simple kidney cyst, a thin-walled sac of clear fluid that grows on or in the kidney. The usual operation is called laparoscopic de-roofing. The surgeon reaches the cyst through a few small cuts, drains the fluid and cuts away the dome of the cyst that bulges from the kidney surface. With its roof removed, the cyst stays open to the space around the kidney, and any fluid its lining still makes is simply absorbed by the tissues around the kidney.
Simple kidney cysts are very common, especially after middle age, and most are found by chance on an ultrasound scan done for another reason. Most stay quiet for life and need nothing more than reassurance. Renal cyst surgery is for the small group of cysts that grow large enough to cause symptoms.
At Dar Al Kamal Hospital, Sharjah, renal cyst surgery is performed by the specialist urologist using the techniques described on the laparoscopic urology page.
Who needs it
Renal cyst surgery suits people with a simple cyst that causes a persistent ache in the side or back, a feeling of fullness, repeated infection of the cyst, bleeding into it, or pressure on the kidney's drainage system that slows the flow of urine. Rarely, a cyst pressing on the kidney's blood supply contributes to raised blood pressure.
The first step is confirming that the cyst is truly simple. A CT or MRI scan grades kidney cysts by their wall, contents and any solid areas, and a cyst with thick walls, partitions or solid parts is managed as a possible tumour through the kidney cancer treatment pathway instead. Many kidneys with dozens of cysts reflect an inherited condition, covered on the polycystic kidney disease page, which is managed differently.
Needle drainage under scan guidance is a simpler alternative. It relieves symptoms and helps show whether the cyst is the cause of the pain, although the cyst often refills over time. Your urologist explains the options, and the choice between watching, draining and de-roofing is made with you.
What happens
Renal cyst surgery is done under general anaesthesia. You lie on your side, and the surgeon makes a few small cuts in the abdomen or flank. Gas gently expands the working space, a camera gives a magnified view on a screen, and slim instruments reach the kidney.
The surgeon separates the fat to expose the cyst, drains the fluid with a fine needle, and then trims away the thin dome where it rises above the kidney surface. The fluid and the removed wall go to the laboratory to confirm that the cyst is simple. The edge is sealed to stop oozing, and sometimes a pad of the fat around the kidney is tucked into the base of the cyst to keep it open. The small cuts are closed with dissolving stitches or skin glue.
After the operation you are encouraged to walk early, and you go home once you are eating, passing urine normally and comfortable on tablets.
Preparing for it
A pre-operative assessment checks your heart, lungs, blood count and kidney function. Bring your latest scan report and a full list of medicines; blood thinners and diabetes medicines need a specific plan, and you receive fasting instructions for the day.
Wear loose clothing that sits comfortably over the small wounds on the way home, and arrange a lift. If surgery falls near Ramadan, raise it early so fasting and medicines can be planned together.
Afterwards
Soreness around the small wounds and a shoulder-tip ache from the gas used during surgery are common and ease over the first days. Keep walking little and often. Keep the wounds clean and dry, and in the Sharjah heat change out of sweaty clothing promptly so the dressings stay dry. Drink water steadily through the day.
Light activity and desk work usually resume early after keyhole surgery, while heavy lifting and manual work follow a longer plan. Your urologist gives you a personal timeline and arranges a follow-up scan at Dar Al Kamal Hospital, Sharjah to check that the cyst has collapsed.
Contact the hospital urgently if a wound becomes red, swollen or leaks, if you develop a fever, or if pain in your side increases instead of easing. **Go to the emergency department straight away if you feel faint or dizzy, have severe abdominal pain or swelling, or notice heavy blood in your urine.**
Cost and insurance
Most UAE insurance plans cover renal cyst surgery when the cyst is causing symptoms or affecting the kidney, and pre-approval is required, supported by the CT or MRI report and a record of the symptoms. A cyst found by chance and causing no symptoms is usually treated as needing observation only, so documentation matters. Dar Al Kamal Hospital, Sharjah can help you check your cover on 06 599 7777.

Frequently asked questions
What are the risks of renal cyst surgery?
Renal cyst surgery carries the risks of any keyhole operation, including bleeding, infection, reactions to anaesthesia and, rarely, injury to nearby organs or to the kidney's drainage system, which can cause a urine leak. The cyst can occasionally refill, and sometimes the operation needs to be converted to open surgery for safety. Your urologist explains how these risks apply to you.
Do all kidney cysts need surgery?
Most simple kidney cysts need no treatment and cause no symptoms. Surgery is considered only when a simple cyst is large and causes pain, infection, bleeding or pressure on the kidney's drainage system, confirmed by scans.
Can a simple kidney cyst turn into cancer?
A truly simple kidney cyst, confirmed on CT or MRI, very rarely becomes cancer. Cysts with thick walls, partitions or solid areas are graded differently and may need closer monitoring or treatment as a possible tumour.
Why not just drain the cyst with a needle?
Needle drainage is simpler and relieves symptoms, but the lining of the cyst keeps producing fluid, so the cyst often refills over time. De-roofing removes the cyst's dome so fluid drains away permanently, which is why it is chosen for cysts that keep causing symptoms.
Is renal cyst surgery the same as treatment for polycystic kidney disease?
Renal cyst surgery treats one troublesome simple cyst and is different from the care of polycystic kidney disease, an inherited condition in which many cysts grow in both kidneys and are managed mainly by a nephrologist.
Will I lose kidney function after renal cyst surgery?
Renal cyst surgery removes only the cyst wall above the kidney surface and leaves the kidney tissue itself in place, so kidney function is usually unchanged. Relieving pressure from a large cyst can help the drainage of urine.
