Laser Induced Shockwave Lithotripsy (LISL) is a medical procedure used for the non-invasive treatment of urinary tract stones, specifically kidney stones and ureteral stones. It involves the use of laser technology to generate shockwaves that break down the stones into smaller fragments, making them easier to pass through the urinary system.
During the procedure, a laser is directed at the stone, emitting high-intensity pulses of light. The laser energy is absorbed by the stone, causing rapid heating and expansion within the stone. This sudden expansion creates a shockwave that propagates through the stone, leading to its fragmentation. The fragmented stones are then naturally passed out of the body through urine.
LISL is a preferred alternative to conventional treatment methods such as surgery or extracorporeal shockwave lithotripsy (ESWL) which involves using external shockwaves to break down the stones. This is because LISL offers several advantages such as enhanced precision, reduced damage to surrounding tissues, and a reduced risk of complications.
The procedure is typically performed under local or general anesthesia, depending on the patient's condition, and is usually completed within a single session. Post-procedure, patients may experience some discomfort, blood in urine, or mild pain, which generally subsides within a few days.
Laser Induced Shockwave Lithotripsy has revolutionized the management of urinary tract stones, providing a less invasive and more effective treatment option for patients. Its efficiency, safety, and reliability have made it widely used in urology clinics worldwide.
