The urinary bladder was excised, and the ureters were implanted into an isolated segment of distal jejunum and ileum in three experimental dogs. The isolated bowel loop was drawn through the pelvic canal within the external anal sphincter to exit ventral to the anus. The dogs were evaluated for urinary continence, urinary tract infection, and renal function for up to 6 months postoperatively. Urinary continence did not return. Continuous urine leakage caused perineal scalding. The cutaneous openings of the isolated bowel loops developed strictures. Serum creatinine and urea nitrogen concentrations did not increase. Excretory urography and retrograde radiographic studies of the bowel loop were performed periodically. Unilateral hydronephrosis was observed in two dogs 2 weeks postoperatively. The remainder of the excretory urograms were normal. Ureteral reflux was observed commonly on retrograde contrast studies. Positive bacterial cultures were obtained from all bowel loops and kidneys at necropsy. Alpha‐streptococcus, Escherichia coli , and Proteus spp. were isolated most frequently. Mild pyelitis was seen in histopathologic examination of the kidneys after necropsy. Urothelium replaced bowel mucosa near the site of ureteral implantation. This method of urinary diversion is not satisfactory for clinical use.
