Individuals who are paralyzed or are unable to adequately pass urine may require the use of small plastic tubes (catheters) placed into the bladder.

Replacement can be done with an artificial urinary bladder, an artificial organ. On January 30, 1999, scientists announced that a lab-grown bladder had been successfully transplanted into dogs. These artificial bladders worked well for almost a year in the dogs. In 2000, a new procedure
