title: Hypergastrinemia following antral gastrocystoplasty.
abstract: Antral gastrocystoplasty has been previously described as an effective method of bladder augmentation or replacement. Six dogs underwent gastrocystoplasty. Two bladders were augmented utilizing the gastric fundus, one antral augmentation was performed, and three total bladder replacements were created utilizing the antrum. Each dog was followed for at least twelve months or until death from peptic ulcer disease with periodic evaluation for urinary continence, serum gastrin level, serum electrolytes, urine culture, urine pH and the radiographic appearance of the urinary reservoir and upper tracts. All four dogs with antral gastrocystoplasties developed severe hypergastrinemia and two demonstrated gross ulcers. In contrast, the two dogs with fundic augmentation did not show elevation of serum gastrin levels or evidence of peptic ulcer disease. Severe hypergastrinemia can be expected following antral gastrocystoplasty and the resultant ulcer disease can be fatal.
