title: [An alternative continence mechanism for continent catheterisable micturation].
abstract: OBJECTIVE
  The creation of a stable, reliable, continent and easily catheterisable continence mechanism is an essential prerequisite for the construction of a continent cutaneous urinary reservoir. Although a substantial number of surgical methods has been described, construction is still a complex surgical procedure. The aim of this study was the evaluation of a new method for a continence mechanism using stapled small or large intestine.
  
  
  METHODS
  Small and large pig intestine was used for construction. For stapling the tube a 3 cm or 6 cm double row stapling system was used. Two variations using small and large intestine segments were constructed (IL 1, COL 1, COL 2). A 3 or 6 cm long stapler line was placed alongside a 12 Fr catheter positioned at the antimesenterial side creating a partially two-luminal segment. The open end of the non-catheterised lumen and the opposite intestinal end were closed by continuous sutures. The created tube was then embedded into the pouch. Pressure evaluation was performed for each variation. Intermittent external manual compression was used to simulate sudden pressure exposure.
  
  
  RESULTS
  Construction times for the IL 1 and COL 1 variations were 10 +/- 1.5 min and 6.2 +/- 1.3 min for COL 2. All variations showed no leakage during filling or external compression. The maximum capacity was lower for the IL 1 compared to the COL variation. The maximum pressure levels reached did not differ significantly.
  
  
  CONCLUSIONS
  The described technique is an easy and fast method to construct a continent and easy to catheterize continence mechanism using small or large intestine.
