Ureteral obstructions are blockages in your urinary tract, which includes your kidneys, bladder, the tubes that carry urine from your kidneys to your bladder (ureters), and the tube that connects your bladder to the outside of your body (urethra). Blockages can develop for many reasons, including gastrointestinal problems.
Ureteral obstructions are more common in men, especially as they get older and their prostate gland enlarges.
Obstructions can be cured with surgery, but they need to be treated promptly. If they’re not, they can lead to severe illness, kidney damage and life-threatening infections.
