To determine the usefulness of antral bladder controlled by the pyloric sphincter denervated for urological applications, bladder replacement was performed in 17 dogs using the antral segment with its own sphincter, initially with the pylorus supplied by the left gastro-epiploic artery, and later by the right gastro-epiploic artery. The smooth pyloric 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 reimplantation of the ureters in the gastric wall are difficult. IVP and cystography indicated good function of the antral pouch, with no reflux. The antral bladder controlled by the denervated pyloric sphincter could be a possible alternative in the surgical management of neurogenic or exstrophic bladder.
