Kidney stones can be an extremely painful condition that affects millions of people worldwide. They are hard deposits composed of minerals and salts that form inside the kidneys.
While small stones often pass through the urinary tract without causing any symptoms, large stones can cause severe pain, blockages, infections, and even kidney damage. In the past, surgery was the only option for removing kidney stones that did not pass naturally.
However, modern medicine has developed several advanced techniques for kidney stone removal that are less invasive, safer, and more effective than traditional surgical procedures. In this article, we will explore these techniques in detail.
1. Shock Wave Lithotripsy (SWL)
SWL is the most common and non-invasive treatment for kidney stones. It uses high-energy shock waves to break the stones into small fragments that can then pass through the urinary tract.
During the procedure, the patient lies on a special table, and a machine delivers shock waves to the kidney area through the skin. The procedure usually takes 30 to 60 minutes, and the patient can go home the same day. However, some patients may require more than one session if their stones are too large or dense.
2. Ureteroscopy
Ureteroscopy is a minimally invasive procedure that uses a thin, flexible tube called a ureteroscope to remove kidney stones.
The ureteroscope is inserted through the urethra and bladder into the ureter, and a small camera at the tip of the scope helps the surgeon locate the stone. Then, the surgeon uses small instruments to grasp the stone and remove it or break it into smaller pieces. This procedure is performed under general or local anesthesia, and the patient can go home the same day or stay overnight if needed.
3. Percutaneous Nephrolithotomy (PCNL)
PCNL is a surgical procedure that is used to remove large kidney stones that cannot be treated with SWL or ureteroscopy.
During the procedure, a small incision is made in the patient’s back, and a special instrument called a nephroscope is inserted into the kidney to locate the stone. Then, the surgeon uses laser or ultrasound energy to break the stone into small pieces that can be removed with forceps. The procedure is performed under general anesthesia and requires a hospital stay of several days.
4. Micropercutaneous Nephrolithotomy (micro-PCNL)
Micro-PCNL is a newer and minimally invasive version of PCNL. It uses a small nephroscope that is about half the size of traditional nephroscopes, which means that the incision can be much smaller (less than 1cm) and the recovery time can be faster.
The procedure is performed under general anesthesia, and patients can often go home the same day or stay overnight if needed.
5. Holmium Laser Lithotripsy
Holmium laser lithotripsy is a non-invasive procedure that uses laser energy to break kidney stones into small fragments that can pass through the urinary tract.
The procedure is performed under general or local anesthesia, and a small, flexible fiber optic scope is inserted through the patient’s urethra into the bladder and then into the ureter. The laser is then used to break up the stone, and the fragments are removed with a small basket or forceps. The procedure usually takes less than an hour, and the patient can go home the same day.

6. Laparoscopic Surgery
Laparoscopic surgery is a minimally invasive procedure that is used to remove large kidney stones or stones that are stuck in the ureter.
During the procedure, the surgeon makes several small incisions in the patient’s abdomen and inserts a laparoscope, which is a thin, lighted tube with a camera at the end. Then, the surgeon uses small instruments to remove the stone or break it into smaller pieces. The procedure is performed under general anesthesia and requires a hospital stay of several days.
7. Percutaneous Nephrolithotripsy (PNL)
PNL is a minimally invasive procedure that is used to remove large or complex kidney stones.
The procedure is similar to PCNL, but instead of making an incision in the patient’s back, a small puncture site is made in the skin and a nephroscope is inserted into the kidney to locate the stone. Then, the surgeon uses laser or ultrasound energy to break the stone into small pieces that can be removed with forceps. The procedure is performed under general anesthesia and requires a hospital stay of several days.
8. Robotic Surgery
Robotic surgery is a minimally invasive procedure that uses highly advanced robotic technology to assist the surgeon in removing kidney stones.
The surgeon controls a robotic arm with a camera and small instruments from a console, and the robot provides a 3D image of the surgical field. This allows for precise and more effective stone removal, with less blood loss and scarring. The procedure is performed under general anesthesia and requires a hospital stay of several days.
9. Extracorporeal Shock Wave Lithotripsy (ESWL)
ESWL is a non-invasive procedure that uses high-energy shock waves to break kidney stones into small fragments that can pass through the urinary tract.
The procedure is similar to SWL, but instead of delivering the shock waves through the skin, they are delivered through a water-filled cushion that is placed against the patient’s body. The procedure usually takes about an hour, and the patient can go home the same day.
10. Natural Remedies
While advanced medical techniques for kidney stone removal can be very effective, there are also some natural remedies that can help prevent kidney stone formation and reduce the risk of recurrence.
Drinking plenty of water, reducing sodium intake, and eating a diet rich in fruits and vegetables are some of the most effective natural remedies for kidney stones. Herbal supplements such as chanca piedra, nettle leaf, and dandelion root can also help dissolve and flush out kidney stones.
Conclusion
Kidney stone removal can be a complex and painful process, but with modern advances in medical technology, there are now several minimally invasive and effective techniques available to patients.
These techniques range from non-invasive shock wave lithotripsy to minimally invasive ureteroscopy, laparoscopic surgery, and robotic surgery. Natural remedies can also help prevent and treat kidney stones. If you are experiencing symptoms of kidney stones, talk to your doctor about the options that are available to you.
