What are Ureter Stones?

Ureter stones are small stones that form in the kidney and pass into the ureter. These stones are formed from the crystallization of minerals from stagnated urine.

What causes Ureter stones?

There is a delicate balance maintained in the urine in our body. When this balance of minerals is disturbed, ureter stones are formed. Some of the reasons for the imbalance are:

  • Lack of enough fluid in the body

  • Hormonal imbalance

  • Intake of a diet which is high in oxalate, sodium and protein

  • Family history

Symptoms / when to call your doctor

When the stone is stationary in the kidney, it does not cause any pain. But, when it moves from the kidney into the ureter, it causes symptoms like:

  • Extreme pain in the back and sides

  • Pain while passing urine

  • Nausea and vomiting

  • Red or brown urine

Why you should see a doctor?

You should see a doctor if you have unbearable pain which makes you vomit. This is because the pain will not subside till your doctor treats you for the ureter stone.

How is it diagnosed?

The doctor can diagnose ureter stones by a physical examination to understand where the pain is originating from. In addition to the physical exam, the doctor might advise:

  • Blood and urine tests

  • Imaging tests like CT scan or X ray

Dietary Restrictions

It's best to avoid food which are rich in minerals which form ureter stones. Some of the diet recommendations are:

  • High intake of water and fluids

  • Avoiding salty, high protein and fatty food

  • Having citrus fruits like lemon, oranges, sweet lime is helpful
