STUDY OF A CONTINENT BLADDER IN THE DOG B Y OPENING AN ANTROPYLORIC GRAFT ONTO THE ABDOMINAL-WALL - (7 CASES PERFORMED BETWEEN 1980 AND 1983)

To determine the usefulness of antral bladder controlled by the pylori c sphincter denervated for urological applications, bladder replacemen t was performed in 17 dogs using the antral segment with its own sphin cter, initially with the pylorus supplied by the left gastro-epiploic artery, and later by the right gastro-epiloic artery, The smooth pylor ic muscle was denervated to obtain permanent spasm and pulled through the striated anterior abdominal muscle. Both ureters were anastomosed by a Cohen's procedure, The best results were obtained with a gastric pouch supplied by the right gastro-epiploic artery; dissection and rei mplantation of the ureters in the gastric wall are difficult. IVP and cystography indicated good function of the antral pouch, with no reflu x. The antral bladder controlled by the denervated pyloric sphincter c ould be a possible alternative in the surgical management of neurogeni c or exstrophic bladder.
