Abstract
While performing a colocystoplasty for cancer of the urinary bladder, we found that the stomach was low-lying and that the pylorus could reach the pelvis with ease. It then occurred to us that the pyloric portion of the stomach could be used to replace the urinary bladder, after which the duodenum could be anastomosed to the divided urethra. As we were not certain whether this operation would he feasible, we studied it in dogs. Technically it was difficult, but after losing some dogs we managed to succeed in performing the operation and grafted a pyloric portion of the stomach to the urethra of the dogs. A study was made on both the function of this new bladder and the gastric secretion. After two years we were quite satisfied that the gastric pouch would serve as a urinary bladder and that there was no hyperchlorcaemic acidosis in these dogs.
