The ureters are the urine tubes that go from the kidney to the bladder. Bladder and ureter injuries are rare with laparoscopic surgery, occurring in only 3 to 5 out of every 1,000 cases. These types of injuries include perforation and thermal injuries. In most cases, these injuries are treated with the placement of a plastic tube, called a catheter, into the bladder for seven to ten days, along with antibiotics. In rare cases, these injuries require switching to either an open operation, where the urologist places thin tubes called stents into the ureters, or a repeat laparoscopic surgery at a future time. Sometimes, an injury might not appear at the time of the operation, but can show up later. This may require another surgery to repair the damage.
