In the last years particular surgery operations became refined for the techniques and therapeutics progresses also developed in this field. This has allowed with major security to accomplish engagemently reconstruction operations after removal of the bladder, especially for cases of neoplastic pathology, to offer the patients a more normal quality of life avoiding urinary derivations that should change the performance of "EGO". After the operations of radical cystoprostatovesciculectomy different methods have been presented for the construction of heterotopical and orthotopical neobladder; among these the continent colic orthotopical neovesica of Goldwassern which uses the detubulization right colon, in our opinion could offer best functional and clinic results in virtue of easier execution and to use of minor number of intestinal segments. Moreover, for the peculiar characteristics of colic segment, allow to make a wide tank at low pression with perfect diurnal and nocturnal continence. We have, therefore, presenting the results of our experience regarding 12 cases of continent colic orthotopical neovesica, by Goldwasser, with a follow-up of 1-6 years which have comforted us with the results predicted. Although other techniques may offer similar results we believe that the Goldwasser method is still valid for all the above reasons.
