Also in contrary to Cohen technique, there is no likelihood of ureteral angulation, and ureteral orifices are closer to their natural site which results in the easier retrograde catheterization and ureteroscopy in the future, and unlike the Glenn-Anderson technique, in the present technique, by less manipulation of trigone and less ureteral mobilization, the limitations of favorable submucosal ureter length creation are not present.
