Kidney Cysts Treatment in Mumbai
Can a Kidney Cyst Be Found Accidentally Even When There Are No Symptoms?
Many people first learn they have a kidney cyst after undergoing an ultrasound, CT scan, or MRI for an unrelated medical concern. Seeing the word "cyst" on a scan report can understandably cause anxiety, and one of the first questions patients ask is whether it could be cancer.
The reassuring reality is that most Kidney Cysts are benign, non-cancerous fluid-filled sacs that do not cause serious health problems. In fact, kidney cysts become increasingly common with age and many individuals live their entire lives without ever realizing they have one.
However, not all cysts are identical. While many simple cysts require only observation, some cysts may grow in size, cause symptoms, become infected, bleed, or possess imaging features that require closer evaluation. Distinguishing between a harmless cyst and one that requires treatment is an important part of modern urological care.
Advances in ultrasound, CT scans, MRI, and minimally invasive surgery have made it possible to accurately classify kidney cysts and determine the most appropriate management strategy.

What Are Kidney Cysts?
A cyst is a closed sac filled with fluid. Kidney Cysts generally have a thin wall and arise from the surface or within the filters (nephrons) of the kidney.
They vary in size and are usually quite small. Rarely they may become very large and cause symptoms.
How Common Are Kidney Cysts?
Kidney Cysts are very common, especially as one gets older. Up to 50% of people above the age of 50 years have kidney cysts. They usually arise in one kidney but can involve both kidneys with age. Kidney cysts can grow with time.
What Causes Kidney Cysts?
Kidney cysts occur when fluid begins to accumulate in the tubes of nephrons, probably due to blockage of these tubes with age or injury.
Some genetic diseases (Polycystic Kidney Disease) can cause kidney cysts; however, these usually manifest early in life, cysts are multiple, and always affect both kidneys.
What Are Kidney Cyst Types?
Acquired kidney cysts are of 4 types:
Type I – Simple Kidney Cysts – Harmless, <2% risk of cancer
Type II – Cysts with thin internal walls and calcification – 15-20% risk of cancer
Type III – Cysts with thicker internal walls which take up contrast – 33% risk of cancer
Type IV – Cysts with thick, irregular enhancing nodules – 90% risk of cancer
What Are the Symptoms of Kidney Cysts?
The vast majority of cysts cause no symptoms and are detected incidentally when scans are performed for other purposes.
Sometimes they may cause pain in the region of the kidney and if very large they may compress other organs like the stomach.
Complications of the cysts include rupture, bleeding, or infection which can cause pain, fever, or blood in the urine.
Rarely they may affect kidney function and cause high blood pressure.
Cysts are diagnosed by their appearance on ultrasound, CT scan, or MRI and evaluated for the need for Kidney Cyst Treatment.
When Do Kidney Cysts Need to Be Treated?
In most patients, simple (Type I, II) cysts need no treatment.
Only if they are causing significant symptoms or have developed complications like bleeding, rupture, or infection do they need treatment.
If there is a suspicion of cancer (Type III and IV cysts), then a Partial Nephrectomy is indicated.
What Are the Surgical Options for Kidney Cysts?
Surveillance
Most cysts do not need treatment and can remain on regular follow-up with imaging like ultrasound.
Aspiration
A needle is inserted under ultrasound or CT scan guidance to puncture the cyst and drain its contents. This is useful if pus has formed due to infection. Sometimes this is done for patients with very large cysts and the surgeon injects an agent to shrink the cyst (sclerosant). This treatment usually needs to be repeated and is only rarely indicated.
Cyst Decortication
The cyst is drained into the abdominal cavity and its lining is then burnt. This is usually done laparoscopically or through Robotic Kidney Cyst Surgery and has almost no complications.
Partial Nephrectomy
This is recommended for Type III and IV cysts where there is a risk of cancer.
Advantages of Robotic Surgery
Robotic Kidney Cyst Surgery provides significant benefits for both patient and surgeon.
- Smaller incisions with less pain and scarring
- Shorter hospital stay and quick return to normal activities
- Reduced bleeding and blood transfusion rates
- Lower risk for wound infection
- Very quick procedure in cyst surgery
- Shorter ischemia time than laparoscopy and equal to open surgery which results in less kidney damage
- Much more ergonomic than laparoscopy
How to Prepare for Kidney Cyst Surgery?
After your imaging and staging tests (CT scan or MRI), you will discuss your options with your urologist:
- What type of cyst do I have?
- Does it need treatment?
- Can the surgery be done by a minimally invasive approach?
To proceed with surgery, the general instructions are:
- Basic blood and urine tests to assess fitness for surgery
- Cardiac evaluation like ECG and 2D Echo
- To stop blood-thinning medication for 5-7 days before the surgery
- Anesthesia check-up and assessment
- Healthy diet and exercise until the surgery
- Admission the day prior to or on the day of surgery
What to Expect After Kidney Cyst Surgery?
- Resumption of a liquid diet within 6-8 hours after surgery and normal food the next day.
- You will also be able to get out of bed and walk a few hours after surgery.
- Pain after robotic surgery is mild and easily controlled with medications.
- You will have a urinary catheter to drain the bladder for 1 day. If a Partial Nephrectomy has been done, the catheter may be kept longer.
- You are expected to be discharged from hospital in 1 day for cyst decortications and 3-4 days for partial nephrectomy.
- You can resume work in about 2-3 weeks after surgery.
- You can walk as much as you like but we recommend avoiding strenuous activity like lifting weights, golfing, going to the gym, etc. for 1 month after surgery.
What Is the Success Rate of Kidney Cyst Surgery?
Cysts which are aspirated generally recur and may need further treatment.
Cyst Decortication Surgery has a high success rate with minimal complications.
Partial Nephrectomy has an excellent success rate for Type III and IV cysts (>95%).
What Are the Complications of Kidney Cyst Surgery?
Cyst decortication is very safe with minimal complications. Every surgery carries a risk of complications. General complications may include anesthesia-related problems, infection, blood clots (DVT), pneumonia, cardiac events, etc.
In addition, certain specific complications include:
Bleeding
The kidney receives 20% of the blood pumped out from the heart and is a very vascular organ. Bleeding is a risk in these surgeries and transfusion may be required. In partial nephrectomy, cutting through the kidney to remove the tumor can cause bleeding.
Urine Leak
If a part of the kidney which drains urine (calyx or pelvis) has been cut during a partial nephrectomy, urine may leak into the space around the kidney. This generally settles by itself but rarely may need the insertion of a drain or stent.
Injury to Adjacent Organs
Injury to adjacent organs is uncommon but can occur during surgery.
Frequently Asked
Common Questions Answered
Find answers to frequently asked questions about urological treatments and appointments.
Which Cysts Need Treatment?
Patients with significant symptoms, infection, bleeding, rupture, or suspicion of cancer in the cysts need treatment.
Is It Safe to Observe Cysts Without Treatment?
For Type I and II (Simple Kidney Cysts), observation or surveillance is the recommended treatment as these cysts generally pose no harm to the patient.
What Are the Advantages of Robotic Surgery?
It allows a very precise surgery with fewer complications, better functional outcomes, and no compromise in cancer control.
How painful is the surgery?
For robotic surgery, pain is quite mild and easily managed with tablet medications.
When will I be discharged from hospital?
Most patients are discharged in 2-3 days after the surgery.
When can I resume normal work?
Work can be resumed usually 2 - 3 weeks after surgery.
Will I need additional treatment?
Usually no additional treatment is needed.
When can I resume normal work?
Work can be resumed usually 2-3 weeks after surgery.
Most Kidney Cysts are harmless findings that require little more than observation. However, some cysts may cause symptoms or possess imaging characteristics that require closer evaluation and treatment.
Accurate diagnosis through ultrasound, CT scanning, MRI, and Bosniak classification is essential in distinguishing simple cysts from more complex lesions. Modern treatment options range from observation and aspiration to minimally invasive and robotic surgery for selected patients.
