Some common ureteral issues include:
Ureteral obstruction
Kidney stones must move through a ureter and into your bladder before exiting your body (except in the case of surgical removal). But, in some cases, a kidney stone may move into a ureter and get stuck there, a condition called ureteral obstruction.
Ureteral obstructions prevent urine from flowing through and can lead to painful urinary tract infections (UTIs), kidney dysfunction, sepsis (bacterial blood poisoning), and even death.
Ureteral strictures
A ureteral stricture is the narrowing of a ureteral tube. This limits the amount of urine that moves through your ureter, and the tube could narrow so much that it causes a ureteral obstruction.
Ureteral strictures often happen with scar tissue or severe inflammation near the ureter. It’s most common after traumatic injury to the abdominal area but can also occur due to gynecologic or urological surgery complications.
Other types of ureteral issues also occur; for example, some people are born with disorders that affect their kidney, ureter, and overall urinary tract function.
