Reflections on ureterocystomeostomy using a tubular vesical flap.

Authors cite 25 uretero-noecystostomy cases, carried out with the Boari flap technique, as well as their respective results several time after the operation. Authors underline both advantages and disadvantages, of presently most followed technics, i.e. Boari-Küss and Boari-Gil Vernet; furthermore, their experience suggests that vesico-ureteral reflux has never caused injuries to the upper urinary tract; the event a surgeon should be particularly afraid of, is stenosis of the uretero-vesical anastomosis. In order to have an easier anastomosis in case of dilated ureters, they also propose the Boari-Küss technique. while for normal-caliber ureters Boari-Gil Vernet technic is suggested.
