Abstract

The advancement technique according to Cohen has proved to be a simple and reliable antireflux procedure.

I propose a technique of retrograde catheterization of the ureter by bladder puncture with a special trocar in order to facilitate the insertion of the catheter and to avoid trauma of the ureteral mucosa.
