RESUMEN
This study was conducted on 30 dogs divided into three equal groups: Group I underwent vesicomyotomy, group II had vesicomyectomy and group III had vesicomyectomy with demucosulated gastrocystoplasty. All groups were compared pre-and postoperatively as regards bladder capacity, pressure and compliance. The mortality and postoperative complications were recorded. The study concluded that the functional evaluation of various techniques for bladder auto-augmentation showed that bladder capacity increased with a better compliance and without any metabolic complications related to the presence of gastrointestinal mucosa in the augmented unit. The addition of a seromuscular gastric patch to vesicomyectomy improved the functional results and decreased the incidence of complications
