The ureters are the urine tubes from the kidney to the bladder. Bladder and ureter injuries are rare, occurring only 3 to 5 times per 1000 cases. These 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 7 to 10 days along with antibiotics. Rarely, these injuries require switching to an open operation, placing thin tubes, called stents, into the tubes leading away from the bladder, called ureters, by a urologist or a repeat laparoscopy at a future time. Sometimes, an injury may not appear at the time of the operation, but may show up later. This may require another surgery to repair the damage.
