Effect on bladder function of diversion of the contents of the small intestine to the urinary bladder in dogs.
The function of the lower part of the urinary tract after diversion of the contents of the small intestine to the bladder was studied in seven mongrel dogs. Cystometries and isobaric bladder volume were recorded. The observation time varied between six and 48 months. An initial decrease of the bladder volume was noted postoperatively. This decrease was more pronounced at the cystometrographic recordings on awake dogs than at the isobaric bladder volume registrations done under general anesthesia. At the six month examination, the bladder volume was unchanged or increased. The initial reduction in the bladder volume could be explained partly by the construction of the ileovesical anastomosis and, to some extent, by an inflammatory reaction of the bladder wall. No signs of progressive inflammatory reaction, leading to contraction of the bladder, were observed in any dog.
