Ureteral Strictures
Overview and Facts about Ureteral Strictures
Ureteral strictures occur when the ureter — the tube that carries urine from the kidney to the bladder — becomes narrowed due to scarring, inflammation, injury, or other underlying conditions. This narrowing can obstruct urine flow, potentially leading to complications such as infections, kidney damage, and pain.
Why Choose Loyola for Treatment of Ureteral Strictures?
Loyola Medicine offers specialized care for ureteral strictures, utilizing advanced diagnostic and treatment options to restore normal urinary function and improve patient outcomes.
Signs and Symptoms of Ureteral Strictures
Patients with ureteral strictures may experience:
- Pain in the flank (side of the body), lower abdomen, or back
- Difficulty urinating or decreased urine output
- Blood in the urine (hematuria)
- Recurrent urinary tract infections (UTIs)
- Swelling or distention of the kidney (hydronephrosis)
Tests and Diagnosis of Ureteral Strictures
Accurate diagnosis is key to effective treatment. Loyola Medicine's urology team uses various tests to diagnose a patient, including:
- Imaging tests: Ultrasound, CT scan, or MRI to visualize and detect ureter blockages.
- Retrograde urethrogram or antegrade pyelogram: Special contrast dye studies to assess the structure of the ureter.
- Ureteroscopy: A minimally-invasive procedure using a small camera to inspect the ureter and determine the severity of the stricture.
Ureteral Stricture Treatment
Treatment for ureteral strictures depends on the severity and underlying cause. Options include:
- Ureteral balloon dilation or stent placement: A minimally invasive approach to temporarily open the narrowed ureter.
- Endoscopic ureterotomy: A laser or surgical tool is used to remove the stricture.
- Robotic ureteral reconstruction: A robotic-assisted procedure to remove or bypass the stricture while preserving normal urinary function.
- Ureteral reimplantation: Surgical repositioning of the ureter to restore proper urine flow.

Causes and Risk Factors for Ureteral Strictures
Ureteral strictures can occur for several reasons. Sometimes, they develop due to radiation therapy or scar tissue buildup. Inflammation around the ureter, a traumatic injury, or complications from past surgeries can also lead to these blockages. Additionally, some people may be born with a ureter obstruction or experience strictures after passing a kidney stone. If left untreated, strictures can lead to the following:
- Persistent urinary infections
- Kidney damage or failure
- Severe pain and discomfort
- Increased risk of bladder dysfunction
