Retrograde Catheterization of the Ureter After Antireflux Plasty by the Cohen Technique of Transverse Advancement

Abstract

In 200 cases the antireflux plasty by the Cohen advancement technique proved to be a simple and reliable method of reflux treatment. The resulting impossibility of normal endoscopic retrograde catheterization of the ureter is a major drawback of this technique. A technique is proposed for retrograde catheterization of the ureter after the Cohen procedure. With the patient under general anesthesia, the bladder is punctured with a thin trocar by a stab incision at the appropriate pole of the suprapubic skin incision scar. The trocar is directed under endoscopic control to the ureteral orifice, while the ureteral catheter is carefully inserted into the ureter. This method proved to be easy and without major risk in 5 children.
