urologyhealth.orgESWL accomplishes stone fragmentation by utilizing shock waves generated by a sophisticated spark plug electrode housed within a lithotripter device. These shock waves are generated by the lithotripter outside of the human body and the energy generated travels through the body converging onto the stone resulting in fragmentation.
What is ESWL surgery?
Extracorporeal Shock Wave Lithotripsy (ESWL) The introduction of extracorporeal shock wave lithotripsy (ESWL) in the early 1980s revolutionized the treatment of patients with kidney stone disease. Patients who once required major surgery to remove their stones could be treated with ESWL, and not even require an incision.
How long does it take for ESWL to work?
Since the procedure is non-surgical, most patients can get back to their daily physical activities within one to two days, and can return to their regular diets. However, it can take between a week and several weeks for the stones to fully pass. Is ESWL Right for You? Though ESWL is widely used, not every patient is an ideal candidate.
Can ESWL work for kidney stones?
ESWL may work best for kidney stones in the kidney or in the part of the ureter close to the kidney. Your surgeon may try to push the stone back into the kidney with a small instrument (ureteroscope) and then use ESWL. Are pregnant. The sound waves and X-rays may be harmful to the fetus. Have a bleeding disorder.
How does a lithotripsy machine work?
An extracorporeal shock wave lithotripsy machine uses shockwaves to break down stones. It is common to develop stones in the kidneys, gallbladder, or ureter. Sometimes stones are small enough to leave the body during urination without a person noticing. Large stones, however, can cause pain and block the flow of urine.
How is ESWL procedure performed?
ESWL is most often performed using IV sedation anesthesia or general anesthesia as an outpatient procedure. In certain cases, a small piece of plastic tubing called a “stent” may need to be placed up the ureter just prior to the ESWL to assist in stone fragment passage.
What is the best surgery for kidney stones?
Surgery for Kidney Stones. Extracorporeal shockwave lithotripsy (ESWL) is the most frequently used procedure for the treatment of kidney stones.
When should infected kidney stones be removed?
Infected kidney stones should be removed shortly after detection or diagnosis. The infected stones generally grow rapidly and serve as a nidus (or center) for further stone formation. This stone matrix is believed to protect the bacteria from antibiotics. In essence, antibiotics cannot clear the associated infection unless the stone material is completely removed.
What is the recovery time for kidney stone laser surgery?
There is also normally some pain when the shattered stone fragments pass through the urinary tract, although this pain is typically much less intense than what it would be if the stone weren’t broken up. In most cases, a person should be fully recovered from laser surgery for kidney stones within a few weeks.
