Ureterectomy is a surgical procedure that involves the removal of one or both ureters, which are the tubes that carry urine from the kidneys to the bladder. This operation is typically performed to treat conditions such as cancer, severe injury, or obstruction in the ureters. The procedure can be done using traditional open surgery or minimally invasive techniques, such as laparoscopy. After the removal, doctors may create a new pathway for urine to exit the body, often connecting the kidneys directly to the bladder or using a nephrostomy tube.
