Ureteral Stones

Ureteral stones are stones that form in the kidney and travel down into the ureters (the tubes that carry urine from the kidneys to the bladder) where they become lodged. The ureters are very narrow tubes and stones that travel into them often are not able to pass through or travel down to the bladder, causing extreme discomfort.  Sometimes, a kidney stone that has passed into the ureter can block the flow of urine, causing severe pain and can lead to other symptoms.

Symptoms of Ureteral Stones

Ureteral stones are more likley to cause symptoms than some smaller kidney stones because the ureters are so narrow and stones cannot pass through. Common symptoms of ureteral stones include:

  • Pain in the flank area, upper back, or upper abdomen area
  • Blood in the urine that is visible or non visible (hematuria)
  • Nausea and vomiting
  • Fever, which is associated with infection and can become serious if not treated


Diagnosis and Treatment

Diagnosis and treatment of ureteral stone are similar or the same as the diagnosis and treatment of kidney stones, since this is where ureteral stones originate.
