Editing Orthotopic Urinary Diversion (section)

== Basic principles for successful outcome of continent orthotopic urinary diversion (3): ==

# '''Adequate external sphincter mechanism and non-obstructed urethra'''
# '''Compliant reservoir''' to maintain a low pressure throughout the filling phase
#* '''Best achieved by opening the bowel segment longitudinally to completely detubularize it''' and folding it to create a spheric shape
# '''Capacious reservoir''' to allow for reasonable voiding intervals

** '''In general, this should be at least 300-500 mL once the pouch is mature'''
** All bowel segments effectively stretch over time if there is adequate outflow resistance, though colonic segments do not stretch up as easily
** '''Small bowel, when available, has advantages over colon in terms of wall compliance and ability to stretch, as well as reduced mucous formation'''
