title: Long-term evaluation of the effect of catheter materials on urethral tissue in dogs.
abstract: A surgical procedure was developed which allowed for the long-term evaluation of the effect of candidate Foley catheter materials on urethral tissue. The dog provided a satisfactory animal model since, after being subjected to the described procedure, this animal remained continent and free of urinary tract infection. Also, each animal served as its own control by examining tissue from a portion of the urethra which was not in contact with the implanted material.
