A comparison of two continent catheterizable vesicocutaneous techniques.

In a rabbit model we describe and compare two continent catheterizable diversion techniques for which the bladder is intact and the stoma is situated in the lower abdomen. Both mechanisms are formed from a short segment of ileum; one utilizes the principles of the encircling loop technique as described by Koff and the second, the Kock principle (intravesical nipple). Both models were evaluated for the following parameters: ease of catheterization (87%, 79% respectively), continence (91%, 86% respectively), and ease of construction. We present evidence that both techniques are applicable to the clinical setting.
