The urodynamic characteristics of different ileal reservoirs: an experimental study in dogs.
Using adult mongrel dogs, the urodynamic characteristics of three types of ileal reservoirs were studied and compared. Segments of ileum of the same length were utilized to construct simple loop pouches (five dogs), DeKlerk pouches (five dogs) and Kock pouches (five dogs). Six to eight weeks after surgery, urodynamic evaluation was carried out. This included determination of the volume/pressure relationship and measurement of the contractions of the circular and longitudinal muscle fibers. Results indicate that the Kock pouch offers the best features in terms of the volume capacity, the volume/pressure relationship and contractile activity. Detubularization abrogated the muscle tone but it did not affect the phasic contractile activity of the circular muscle layer.
