Lithotripsy works in the form of sound waves to break up large kidney stones into smaller pieces. These sound waves are high energy shock waves and the most common form of lithotripsy is extracorporeal shock wave lithotripsy (ESWL).
Interestingly Extracorporeal means “outside of the body”, it can be understood like that it refers to the source of the shock waves. During ESWL, a Lithotripter generates the shock waves; these waves travel into the patient’s body and break apart the stones.
SWL is a nonsurgical technique which may treat kidney or ureter stones (ureter is a tube which connects kidney to the urinary bladder) by using high energy shock waves. Stones get broken into “stone dust” and pass out in urine. If after one procedure large pieces remain; another procedure could take place.
Our kidneys excrete waste and extra fluid from the blood in the form of urine. Sometimes when someone has too much of waste and not enough fluid in blood, the waste builds up and sticks together in kidneys. These waste clumps are Kidney Stones Specialist Doctor Ahmedabad.
The surgeon places the water-filled cushion on the patient’s abdomen or behind the kidney. The patient’s body is positioned in some particular way so the sound waves could work better and target the stones in an appropriate way. About 1-2 thousand shock waves apply to crush the stones. This procedure takes 45-60 minutes.
If the doctor thinks it necessary, he inserts a tube through the bladder and threads it up to the kidney just before SWL. If the ureter is blocked then these tubes or stents are used especially if there is a risk of infection, intolerable pain or reduced kidney function. After an hour the patient can go home. The patient may be asked to drink plenty of liquid, strain urine through the filter and recover stone pieces for testing. The patient may need to take antibiotics and painkillers.

Ureteral stones are not different but are kidney stones that stuck in one or both ureters (the tubes which carry urine from kidneys to the bladder) if the ureteral stone have bigger size; it blocks the flow of urine and this blockage causes severe pain and discomfort.
Kidney stones occur from the excess concentration of minerals and salt in urine. These minerals and salts form crystals that grow into stones. Maximum kidney stones are calcium based.
Many kidney stones are small; even smaller then, to see with naked eyes, pass through the urine and do not cause any problem. Larger stones that get stuck in the urinary tract cause pain which may be severe and increases with time.
Before doing the Lithotripsy, the doctor will do tests so that the number of stones could be determined, as well as their size and location. Doctors inject a dye into a vein, so that a particular type of X-Ray intravenous pyelogram (IVP) which helps to locate the stones, this dye goes in the body and travels in the blood to kidneys, ureter, bladder and highlights the stones in X-Ray.
In the procedure, the doctor places an intravenous (IV) line in the patient’s arm to administer anesthesia and provide pain medication. After lying on the table, lithotripter takes place to target the location of stones; the doctor passes a water-filled cushion between the body so that shockwaves could take place properly. Your doctor may place a stent in the ureter to help the broken stone pass. After the treatment; the patient may pass the stone and its particles in urine for several weeks.
