What is Ureteric Stricture?
A ureteral stricture is a narrowing of the lumen of the ureter, the duct that carries urine from the
kidneys to the bladder, resulting in an obstruction. Ureteral stricture may arise from a variety of
causes depending on how they develop. They may be benign or malignant.
- loin lump
- flank tenderness
- Urinary tract infection
- External trauma may develop after treatment for another condition.
- Ureteral stricture may be inflammatory due to gonorrhea, tuberculous urethritis, or
schistosomiasis, or rare complication of cancer.
- A non-anastomotic ureteral stricture can be developed after stone impaction or upper urinary tract endoscopy, as well as following pelvic radiation therapy and a variety of open and laparoscopic surgical procedure or other trauma.
- Anastomotic ureteral stricture may develop as a result of urinary diversion surgery.
It is diagnosed by IVU (Intravenous Urogram) or retrograde urethrogram to regulate the site and degree of the stricture. There are many minimally invasive treatments for patients with ureteral strictures. A doctor may perform balloon dilation as the first step in treatment, mainly in patients
who have non-anastomotic strictures?
For ureteral strictures that do not respond positively to dilation alone, an endoscopic incision is the procedure of choice for most patients.
