Transureteroureterostomy (TUU) is a procedure in which one ureter is divided and then connected (re-routed) into the other. It is performed when a distal ureter needs to be bypassed and can be performed instead of a psoas hitch or Boari flap. It may be preferable if the patient has had prior radiation therapy to the pelvis or prior extensive pelvis surgery.
The main drawback of a TUU is that in order to treat one ureter, both kidneys and ureters are potentially put at risk (e.g. a distal ureteral stone now causes hydronephrosis in both kidneys).
