Ureteral reimplantation is used to treat reflux (REE-flux), a condition in which urine from the bladder is able to flow back up into the kidneys through the tubes that connect the kidneys with the bladder.
When these tubes, called the ureters are working properly, urine flows only one way out through them from the kidneys and into the bladder so that it can leave the body. The ureters connect to the bladder through a tunnel that acts as a valve to keep urine from flowing backward.
Sometimes, a ureter has a bad connection to the bladder wall. When there is not enough of the tunnel at the connection point, reflux will occur. If left untreated, reflux can cause scarring of the kidneys and permanent kidney damage.
When reflux is not expected to go away with time, or is causing kidney damage, surgery is needed.
Surgery to correct reflux consists of changing the way the ureter connects to the bladder by creating a new tunnel into the bladder. The doctor “reimplants” the ureter to fix its connection to the bladder.
