What does hydroureter mean?

Hydroureter refers to the swelling or dilation of the ureter due to the accumulation of urine caused by an obstruction. This condition can arise from various factors, including kidney stones, tumors, or strictures that block urine flow. The increased pressure in the urinary system can lead to complications if not treated promptly. Hydroureter is often diagnosed through imaging studies and may require medical intervention to relieve the obstruction.
