What is the kidney stone?

Kidney stones are composed of substances (like calcium) that are present in the urine. A kidney stone forms when high levels of these substances crystallize into a mass. Most kidney stones form inside the kidney but may move into the ureter (the tube that carries urine to the bladder).

What is shock wave lithotripsy (SWL)?

Shockwave Lithotripsy (SWL) has emerged as the most popular treatment for removing kidney stones. It is a non-invasive procedure in which ultrasonic waves, also known as shock waves, are generated outside the human body and then a machine called lithotripter is used to penetrate through skin and tissues to target the unwanted kidney stones.

When is SWL useful?

Shockwave lithotripsy is most useful when the stones are less than 3cm in diameter. It is best suited for a stone between 2.5 to 3.0cm stones in kidney or ureters.

For whom SWL is not recommended?

Shockwave Lithotripsy is not recommended for the following set of patients:

Preparing for the SWL procedure

The SWL procedure is performed on an empty stomach. So, the patient will be advised to avoid eating any food (solid or semi-solid) at least five hours before the scheduled appointment. If you take any regular medication such as for hypertension, diabetes, and arthritis, then check with your doctor.

Recovery and care

After SWL, the recovery is very fast. Patients can walk up almost immediately after the procedure and most can even resume their daily activities within 48 hours.

Advantages and disadvantages of SWL

The main advantage of shock wave lithotripsy is that it does not require any incision and is completely non-invasive treatment. This ensures shorter hospital stay and faster recovery time.

When was shock wave lithotripsy introduced?

The introduction of extracorporeal shock wave lithotripsy (ESWL) in the early 1980s revolutionized the treatment of patients with kidney stone disease. Patients who once required major surgery to remove their stones could be treated with ESWL, and not even require an incision.

What is ESWL in medical terms?

ESWL involves the administration of a series of shock waves generated by a machine called a lithotripter. The shock waves are focused by x-ray onto the kidney stone and travel into the bodythrough skin and tissue, reaching the stone where they break it into small fragments.

Is ESWL an outpatient procedure?

The Procedure. Because ESWL is a completely non-invasive therapy, most ESWL treatments are performed on an outpatient basis.

How does shock wave lithotripsy work?

Extracorporeal shock wave lithotripsy. All shock wave lithotripsy machines deliver shock waves through the skin to the stone in the kidney. Most but not all of the energy from the shock wave is delivered to the stone. Stone size is the greatest predictor of ESWL success. Generally:

What are the complications of ESWL?

The possible complications of ESWL include: 1 Injury to kidney tissue, such as bruising (hematoma), can occur in a small number of cases, but usually heals without additional treatment. 2 Fragmented stones may accumulate in the ureter and form an obstruction. This is known as a steinstrasse (“street of stones”). A ureteral stent often minimizes any problems associated with steinstrasse. The stent is removed in a few days or weeks. 3 A small percentage of patients undergoing ESWL develop hypertension, although the mechanism is not well understood. 4 An increased risk of diabetes mellitus following ESWL has also been reported. However, these results were not confirmed by a large population study done at the same institution.
