Ureter Stone Symptoms

Stones trapped in the ureter often cause sudden and severe pain. The pain may begin in the side of the abdomen or back and may move toward the groin as the stone travels.

Common symptoms include:

Severe flank pain that comes in waves.
Pain radiating toward the lower abdomen or groin.
Nausea or vomiting.
Blood in urine.
Frequent urination when the stone is near the bladder.

Symptoms of Ureter Blockage or Stricture

When urine flow is blocked or restricted, symptoms may appear gradually.

Common symptoms include:

Persistent flank pain or dull aching pain.
Recurrent urinary infections.
Fever with infection.
Reduced urine output in severe obstruction.
Hydronephrosis was detected on imaging tests.

When to seek emergency care?

Immediate medical attention is required if symptoms become severe.

Seek urgent care if you experience:

Fever with severe flank pain.
Severe pain not relieved by medicines.
Persistent vomiting or dehydration.
Very low urine output.
Heavy blood in urine or clots.

Causes and Risk Factors of Ureter Disease

Ureter disease can develop when the ureter becomes blocked, narrowed, or damaged, affecting the normal flow of urine from the kidneys to the bladder. Early identification of the cause helps guide appropriate ureter disease diagnosis and treatment.

Common Causes
- Kidney stones causing ureter blockage.
- Ureter stricture due to scarring or previous surgery.
- Urinary tract infections causing inflammation.
- Congenital abnormalities of the ureter.
- Tumours affecting the ureter or nearby structures.
- Injury to the ureter during abdominal or pelvic surgery.
- External pressure from surrounding organs or masses.
Risk Factors: The risk of developing ureter disease may be higher in people with:
- A history of kidney or ureter stones.
- Recurrent urinary tract infections.
- Previous urinary tract surgery or procedures.
- Chronic kidney disease.
- Congenital urinary tract abnormalities.
- Certain cancers involving the urinary tract.
- Diabetes or other conditions that increase the risk of urinary complications.
Early evaluation with appropriate tests, such as ureter imaging, CT urogram, or ureteroscopy, can help identify the underlying cause, prevent hydronephrosis, and protect long-term kidney function.
