title: [Retrograde catheterization of the ureter and pyelography using bladder puncture with a special trocar following Cohen's procedure for anti-reflux surgery].
abstract: The advancement technique according to Cohen has proved to be a simple and reliable antireflux procedure. Its major drawback is the impossibility of catheterization of the ureter following this operation because of the transverse position of the ureter. 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.
