A New Device Giving Hope for Kidney Stone Patients
Urinary stones, which are stone-like solid particles in the urinary system, are a common condition that frequently causes severe pain along with other symptoms including nausea, vomiting and blood in the urine.
A clinical trial commencing at Wesley Medical Research is set to explore the efficacy of a new form of treatment using a device called the Enhanced Lithotripsy System (ELS) for urinary stones.
This trial is for participants with urinary stone disease, including those with stones within the ureter (the duct carrying urine from the kidney to the bladder) or renal pelvis of the kidney (that part of the kidney that funnels the urine to the ureter).
The ELS delivers a new form of treatment that breaks up the urinary stone into smaller particles using low-intensity ultrasound (sound waves).
In some ways, an ELS treatment resembles an older form of treatment using pressure waves called Shock Wave Lithotripsy.
While Shock Wave Lithotripsy can be effective for treating some forms of kidney stones, the devices are expensive, bulky and the intensity of the shock waves can cause trauma to surrounding tissue often resulting in patients experiencing pain after the procedure.
In an ELS procedure, a beam of low-intensity acoustic energy is used instead of shock waves. The low-intensity acoustic energy beam is produced by a small component called the ELS “treatment head”.
During the procedure, the treatment head is held against the patient’s skin at a position chosen by the urologist based on knowledge of the stone’s location in the urinary tract.
A special material called Acoustic Enhancer is also used in ELS procedures.
The low-intensity acoustic energy beam emitted by the ELS treatment head is designed to work with the Acoustic Enhancer to erode, pit, and break up stones—without the pain that can come from the intense shock waves used in Shock Wave Lithotripsy.
The ELS is a medical device that is for clinical investigational use only.
This clinical trial is open for recruitment.
