Doctors use the lithotripsy procedure very steadily. It’s one in all the therapeutic options for kidney stones (also called lithos). These are hard deposits of minerals and salts that form contained in the kidneys.
The issue is that when these stones move through the urinary tract and distend it, they cause plenty of pain. They’re also related to obstruction of the urinary tract. Lithotripsy is meant to fragment these stones.
The thought is that the patient can expel them more easily. There are alternative ways of performing the technique and certain essential features to take into consideration before using it. Subsequently, in this text, we’ll explain every little thing it’s best to find out about this procedure.
How does the lithotripsy procedure work?
Lithotripsy, as we identified within the introduction, is a medical procedure used to treat kidney stones. As an article from the Serrate & Ribal Urology Institute explains, the word comes from Greek and Latin. Lithos means ‘stone’ and trip means ‘to crush’.
Kidney stones are a condition with high prevalence in the overall population. Because of this, the lithotripsy procedure has change into a really useful and widely used technique. It consists of fragmenting the stones within the kidney or along the urinary tract to make it easier to expel them with urine.
For this purpose, shock waves or a laser are used extracorporeally and non-invasively. The device used is known as a lithotripter within the case of shock waves. The procedure is painless and doesn’t require manipulation of the patient.
A lot in order that it’s often performed on an outpatient basis and without anesthesia. Other complementary tests, resembling ultrasound and X-ray, are used to locate the precise position of the stones.
The sorts of lithotripsy
There are different modalities of lithotripsy. The 2 fundamental types are extracorporeal shock wave lithotripsy (ESWL) and laser lithotripsy (FURSL).
Each techniques help to fragment stones throughout the renal pathway. Nonetheless, it’s essential to be acquainted with them to know which one is more indicated depending on the patient’s health conditions. The number and kind of stones present even have an influence.
Extracorporeal shock wave lithotripsy
Extracorporeal shock wave lithotripsybecause the name implies, uses shock waves to interrupt up the stones. The machine is a lithotripter. It’s accountable for directing waves to the purpose where the stones are situated.
What is helpful is that these waves only affect the stones. In other words, they don’t damage the skin, muscles, or another tissue. The procedure takes roughly one hour to perform.
Laser lithotripsy
Laser lithotripsy involves inserting a small flexible tube, called an endoscope, through the urinary tract. The endoscope has a camera on the tip that lets the doctors see the within the ducts.
Once they locate the stone, they use a laser directly on the stone to interrupt it into fragments. This system is shorter than extracorporeal shock wave lithotripsy, lasting half an hour.
Nonetheless, the very fact of getting to introduce the instruments may generate more discomfort or discomfort within the patient. As within the previous procedure, the patient can go home on the identical day of the procedure.
How effective is lithotripsy?
Lithotripsy is a widely used technique since it’s considered secure and effective. Based on a study published within the Oman Medical Journalthe success rate is around 88% of cases within the ureter. In kidney stones, the proportion is somewhat lower, but additionally very high (74 %).
As well as, only a few have complications, resembling urinary tract infections. One other article from the National Kidney Foundation states that 70-90% of people that undergo lithotripsy are stone-free within the months that follow.
Nonetheless, it’s possible that on some occasions the fragments should be too large to pass. Under these circumstances, the doctor could have to repeat the procedure if obligatory.

Preparation for the procedure
Before doctors perform a lithotripsy, they should know the patient’s history, treatments, and background. As well as, they typically perform a series of complementary tests. The thought is to attempt to locate the stones and know their dimensions before fragmenting them.
For this purpose, doctors can perform an intravenous pyelogram. It is a test just like an X-ray that uses a dye to locate the stones. They might also prescribe ultrasound scans.
In the times before lithotripsy, the patient could have to stop taking certain drugs. Specifically, anticoagulant drugs, as they increase the danger of bleeding when expelling the stones.
General anesthesia isn’t all the time obligatory. In reality, there are numerous occasions when doctors perform this procedure under local or regional anesthesia on an outpatient basis. Nonetheless, some patients remain hospitalized to watch the opportunity of complications.
What’s the lithotripsy procedure like?
The 2 sorts of lithotripsy are similar but have essential differences. In each of them, the patient is frequently lying down, with or without anesthesia. The procedure itself isn’t painful, however the expulsion of the fragments is.
Among the fragments may cause a blockage within the urinary tract. In these cases, it’s obligatory to perform an endoscopy through the ureter to remove it. As well as, it’s value mentioning that, although less frequent, bleeding, fever, and even infection may occur.
The large difference to bear in mind is that in laser lithotripsy it’ll be obligatory to introduce an endoscope through the patient’s urinary tract. This could be more uncomfortable and unsightly.
Recovery after the lithotripsy procedure
After the procedure, the patient often has to rest within the hospital for at the least one hour. This time could also be prolonged if anesthesia has been used. It’s obligatory to examine that the person is stable and that there aren’t any complications.
In the next days, if the doctors have used extracorporeal shock wave lithotripsy, the patient can return to work. When performed by laser, recovery is slower. It is because the procedure with the endoscope is invasive.
As mentioned above, pain or blood within the urine is more likely to occur after the procedure. Hematomas are also frequent within the skin, in the world where the shock waves have had an impact. It’s subsequently really useful to rest, take painkillers and seek the advice of within the event of any problem or warning sign.

The reality is that kidney stones could be brought on by multiple aspects. Certain aspects influence their occurrence. The incidence could be very high.
