[Detubularized ureterosigmoidostomy (Mainz pouch II). Review and contribution of our results]. / Ureterosigmoidostomía destubulizada (bolsa de Mainz II). Revisión y aportación de nuestros resultados.

We have revised the urinary diversions made through the Mainz Pouch II technique in those patients who needed a radical cystectomy because of a neoplastic disease. We will point out the pre and post operatory manometric studies realised in all of them as well as the different complications which were found. In our opinion, the pressure advantages that such technique is supposed to prove have not succeeded in our studies, that is the reason why we believe that a future research is needed to endorse such operatory modification.
