[The "trouser" technic in the correction of megaureter]

The tailoring normally used in the management of mega-ureter sometimes leads to setbacks as a result of ischemia. In order to attenuate this risk, the author advocates a longitudinal incision, 4 to 6 cm in length, in the middle of the terminal ureter, giving two thin ureteral tubes like a bifid caudal ureter. This leads to a minimal disturbance of the vascularization. It also provides less interference in the emptying of the ureter than the tailoring technique.
