The ureter is the tube that drains urine from the kidney down to the bladder. In some conditions, a portion of the ureter can be narrowed, which is called a stricture.
This can be congenital, or the result of scarring from previous surgery, urinary stones, or other causes.
Patients undergoing treatment such as a ureteroscopy for kidney, ureteric stone management or urinary diversion is at great risk for developing ureteral stricture.
Diagnosis of Ureteric Stricture
Symptoms of ureteral stricture may include pain, loin lump, flank tenderness, and/or urinary tract infection.
Ureteric Stricture Causes
It is diagnosed by IVU (intravenous urogram) or retrograde urethrogram to determine the site and degree of stricture.
- Open or laparoscopic injury
- Radiation therapy
- Urinary diversions
- Renal transplantation
Ureteric Stricture Treatment
- Balloon dilation
- Placement of metal ureteral stents
