N2 - Objective: To create a simple neobladder and determine whether the double-limb U-Pouch (D-LUP) has the same capacity and compliance as a Studer or Camey I neobladder. To develop an orthotopic diversion that can be applied to robotic surgery with laboratory data supporting the concept. Materials and Methods: Kidneys, ureters, bladders, and small intestine were obtained from pigs at the time of scheduled autopsy after completion of institutionally approved investigational trauma protocols. A Camey I neobladder, spherical neobladder, and D-LUP, were constructed from 40-cm segments of small intestine. They were compared for capacity, compliance, and pouch-to-urethra anastomotic distance. Results: The cystometric capacity at 30 cm H2O for the Camey I, Studer, and D-LUP neobladders were 250 mL, 350 mL, and 430 mL, respectively. The pouch-to-urethra anastomotic distance was 0 cm for the Camey I, 10 cm for the spherical reservoir, and 0 cm for the D-LUP. Compliance was 10 mL/cm H20 for the Camey 1, 15 mL/cm H2O for the sphere, and 16 mL/cm H20 for the D-LUP. Conclusion: The D-LUP neobladder was simple to construct, had a more dependent ileo-urethrostomy site, larger capacity, and similar compliance when compared with a spherical neobladder.
