How is renal colic treated?

Treatment for renal colic and kidney stones involves reducing pain and breaking up the stones. In some cases, kidney stones may pass on their own, allowing symptoms of renal colic to resolve. However, it is common for kidney stones to recur. Drinking plenty of fluids may help the stone to pass and may lessen the pain of renal colic.

Medications for renal colic and kidney stones

Certain medications may be used to help break down kidney stones, and other medications may be used to treat pain. Medications for renal colic include:

  • Allopurinol (for uric acid kidney stones)
  • Alpha-blocker medications to help stones pass
  • Antibiotics to clear infections
  • Cystine control medications to reduce cystine levels in urine
  • Diuretics
  • Pain medications
  • Potassium citrate or sodium bicarbonate to regulate urine pH and prevent stone formation
  • Sodium cellulose phosphate to bind calcium in the intestine

Other treatments for renal colic and kidney stones

In addition to medication, other treatments may be required to treat or remove kidney stones. In some cases, surgery may be required. Treatments for kidney stones include:

  • Heat therapy (for pain)
  • Lithotripsy (use of ultrasonic vibration to break down kidney stones)
  • Surgery to remove large stones
  • Ureteral stent placement, to keep the urine tubes from the kidneys to the bladder (ureters) open
  • Ureteroscopy (minimally invasive surgery)

What you can do to improve your renal colic

In addition to following the treatment plan prescribed by your medical professional, you may be able to improve your renal colic by:

  • Drinking plenty of fluids (six to eight glasses of water per day)
  • Using home remedies such as heat pads

What are the potential complications of renal colic?

In many cases, kidney stones will pass on their own. Although renal colic is very painful, it does not usually lead to complications. In some people, however, kidney stones and renal colic may recur. Complications of untreated or poorly controlled renal colic can be serious. You can help minimize your risk of serious complications by following the treatment plan you and your health care professional design specifically for you. Complications of renal colic include:

  • Blockage of the urinary tract
  • Kidney damage
  • Loss of kidney function
  • Recurrence of stones
  • Urinary tract infection
