However, in about 20 percent of cases, the stone is greater than 2 centimeters (about one inch) and may require treatment. Most kidney stones that develop are small enough to pass without intervention. The areas most prone to trapping kidney stones are the bladder, ureters, and urethra. Other stones may have rough edges or grow as large as a pea causing extreme pain as they travel through or become lodged in the urinary tract. Some kidney stones are small or smooth enough to pass easily through the urinary tract without discomfort.

If the stones break free of the kidney, they can travel through, and get lodged in, the narrower passages of the urinary tract. When substances that are normally excreted through the kidneys remain in the urinary tract, they may crystallize and harden into a kidney stone. A stent may be inserted through a special scope into the urinary tract to allow stones to pass more easily. A synthetic, tubular device that may be used along with other procedures. A more invasive surgical procedure using a larger incision to directly access the stone. It involves the removal of a stone through a thin tube tunneled through a small incision in the back into the kidney. A surgical procedure for stones that cannot be treated with lithotripsy or endoscopic procedures.

Percutaneous nephrolithotomy (tunnel surgery).

Endoscopic procedures in which stones in the urethra or ureter may be removed with a device inserted through a short, flexible, lighted tube, called an endoscope. Other procedures that may be used to treat kidney stones include: At the Brady Urological Institute, our surgeons have researched techniques to make lithotripsy safer and more effective, and we incorporate our own findings as well as those of other leading groups to provide a truly state of the art treatment. Although many of these parameters are beyond anyone's control, such as the stone size and location in the kidney, there are other maneuvers that can be done during lithotripsy treatment that may positively influence the outcome of the procedure. It turns out that we can identify some patients who will be unlikely to experience a successful outcome following lithotripsy, whereas we may predict that other patients will be more likely to clear their stones. In the two-plus decades since lithotripsy was first performed in the United States, we have learned a great deal about how different patients respond to this technology. For several weeks following treatment, those small fragments are passed out of the body in the urine.

The shock waves travel into the body, through skin and tissue, reaching the stone where they break it into small fragments. The shock waves, which are generated by a machine called a lithotripter, are focused by x-ray onto the kidney stone.

Lithotripsy involves the administration of a series of shock waves to the targeted stone. Treatment for kidney stones, meaning no incision or internal telescopic As such, lithotripsy is the only non-invasive Major surgery to remove their stones could be treated with lithotripsy, and The introduction of lithotripsy in the early 1980s revolutionized the treatment of patients with kidney stone disease. In order to aim the waves, your doctor must be able to see the stones under X-ray or ultrasound. Lithotripsy allows persons with certain types of stones in the urinary system to avoid an invasive surgical procedure for stone removal.

The shock waves break a large stone into smaller stones that will pass through the urinary system. Lithotripsy treats kidney stones by sending focused ultrasonic energy or shock waves directly to the stone first located with fluoroscopy (a type of X-ray “movie”) or Lithotripsy is a noninvasive (the skin is not pierced) procedure used to treat kidney stones that are too large to pass through the urinary tract.
