Kidney Stone Treatment: More than Relief from Pain

Treatment of kidney stones depends on your stone: where it is and what effect it is having on your urinary tract. You may require nothing but pain management or you may require a surgical procedure. There are several different procedures performed to remove stones:

  • Endoscopic procedures (ureteroscopy)
  • Extracorporeal shockwave lithotripsy (ESWL)
  • Percutaneous nephrolithotomy
  • Open stone surgery

Endoscopic Procedures

These procedures require no incisions: they involve passing a tube with a small camera on the end, called a ureteroscope, through the ureter or kidney to the site of the stone. To relieve obstruction and pain, a stent is placed in the ureter. Different instruments can then be inserted through the ureteroscope to allow fragmentation of the stone. This is called lithotripsy and there are two major technologies used to perform it:

  • Laser lithotripsy, which utilises laser energy to fragment stones.
  • LithoClast™ lithotripy, which allows either ultrasonic or pneumatic fragmentation.

After fragmentation, stone retrieval baskets can be passed via the ureteroscope to extract the stone fragments.

Extracorporeal shockwave lithotripsy (ESWL)

ESWL is a procedure which fragments stones until they are small enough to pass by focusing shockwaves through an acoustic lens, most commonly using electromagnets to generate the shockwave.

The procedure is suitable for small stones, < 2 cm in diameter. It is entirely non-invasive, no tubes or incisions are made. It is is a qday-only procedure performed under general anaesthetic.

Following the procedure you may experience some modest brusiing and blood in the urine. After fragmentation, stones can take up to six weeks to pass. In 25% of cases require more than one treatment.

Percutaneous nephrolithotomy

Some stones located in the kidneys are too complex to remove using ureteroscopy. Percutaneous nephrolithotomy is a procedure in which a small incision in the skin is made under X-ray guidance allowing the surgeon to see inside the kidney using a small tube called a nephroscope.

Like a ureteroscope, this tube contains a camera on the end allowing the stone to be visualised. It can then be fragmented and removed using lithotripsy.

This technique is useful for removal of very large kidney stones, > 2cm in length.

Open stone surgery.

Open stone surgery is very rare in the modern era – less than 1% of cases are treated with open surgery. Open surgery may be necessary for large stones that have been stuck in the ureter for and extended period or for complex kidney stones, called staghorn calculi, that are at risk of completely obstructing the flow from the kidneys and causing tissue damage.

lexible ureteroscopy: a flexible tube is passed through the bladder into the upper urinary tract to allow access to the stone, which is then fragmented or removed.
