What is ESWL?
Sep 1, 2022
ESWL or Extracorporeal Shock Wave Lithotripsy is a minimally invasive procedure used to treat kidney stones. The procedure uses sound waves to break up the stones so they can be passed through the urinary system. ESWL can be performed as an outpatient procedure and does not require anaesthesia. ESWL may not be appropriate for all types of kidney stones. Stones that are too large or too hard may not be able to be broken up with sound waves.
Why and when is ESWL needed?
ESWL as a procedure uses sound waves to break up kidney stones so they can be passed through the urinary tract. The stones are broken into small pieces that can be passed through the urinary tract. ESWL is used when the stone is too large to pass on its own or when other methods, such as medications, or surgeries have failed. ESWL can also treat stones causing pain or blockage of the urinary tract. It is most beneficial for kidney stones that are 5mm or larger in diameter. It is most effective for stones located in the upper part of the ureter, near the kidney.
How is ESWL performed?
During ESWL, the patient lies on a table. The doctor inserts a flexible tube (catheter) into the urethra (the tube that urine passes through). Then an X-ray machine is used to target the sound waves of the kidney stone. As the sound waves hit the stone, they create vibrations that break the stone into small pieces. The small pieces then pass out of the body in urine.
Is ESWL a surgery?
Since its inception in the early 1980s, extracorporeal shock wave lithotripsy (ESWL) has become an increasingly popular treatment for kidney stones. But what exactly is this procedure? Is it surgery? ESWL involves the use of high-frequency sound waves to break up kidney stones. It is a non-invasive procedure that is typically simpler for recovery and healing when compared to regular surgeries that are invasive and can be far more painful too.
Who can use ESWL?
ESWL can be used on patients of all ages and is performed as an outpatient procedure. Further, it is used for most patients with kidney stones, but there are some exceptions. Patients with large kidney stones, pregnant women, and those with certain medical conditions may not be candidates for ESWL.
What are the benefits of ESWL?
There are several benefits of ESWL over traditional surgery for kidney stones.
First, there is no incision or scarring with ESWL.
Second, the risk of infection and complications is lower with ESWL.
Third, recovery time is shorter after ESWL. Most patients are allowed to conduct their normal activities within a few days.
Finally, ESWL is less expensive than surgery.
Is ESWL a painful treatment?
ESWL is usually considered a safe and effective treatment for kidney stones and is less painful. Patients typically have less pain during the treatment which can be due to the shockwaves reaching the muscle, skin, nerves, the deeper structures like ribs.
Does ESWL cause any side effects?
Extracorporeal shock wave lithotripsy or ESWL is generally safe, but here are a few potential side effects that patients should be aware about. These include-
- Blood in urine or around the kidney
- Urinary tract damage
- Painful urination
- Infection
- Ureter blockage
Thus, to avoid such adverse effects, you must choose an experienced doctor and hospital that are well-trained and well-equipped and can provide you with the best treatment.
