How I Do It
Neobladder: How I do it
Patient Inclusion and Exclusion Criteria
Psychosocial
Able and willing to carry out CIC
Good manual dexterity
No urethral problems
Compliant with F/U requirements
Physiologic
Hepatic Function: normal
Renal Function: Cr < 2 or CrCl >40 with equal kidneys
Intestinal Function: No Hx of IBD, Ca/polyps, XRT or extensive resection
Age: <70yrs but individualized
Neobladder: How I do it
Patient Inclusion and Exclusion Criteria
Urethra (male)
TUR Prostatic Fossa
Avoid Orthotopic if any chips are +
Urethrectomy if stromal or ductal invasion present
Urethra (female)
Biopsy  (cold cup) BN pre-op
Exclude patients with > stage T3 disease
Frozen section margin at cystectomy to r/o submucosal spread
Tumor Stage
Exclude patients with grossly + nodes
Exclude patients with > stage T3 disease
Neobladder: How I do it
Technical Points:  Male Cystectomy
Nerve Sparing Procedure
Urethral dissection/reconstruction (Eastham 96)
Neobladder: How I do it
Technical Points:  Female Cystectomy
Minimize surgery in areas of Hypogastric and pelvic plexus
PLND
Pouch of Douglas
Conserve Innervation to Urethra
Minimal dorsal vaginal excision in area of bladder - vagina contact
Dissection of bladder pedicles close to bladder
Use Foley balloon to identify bladder neck
Frozen section on BN
Neobladder: How I do it
Technical Points:  Female Cystectomy
Close vagina perpendicular to incision
Suspend pouch to prevent “pouchocele”
Pelvic Sidewall
Round Ligament
Place Omentum below pouch
reduce risk of fistulas
reduce chance of “pouchocele”
Neobladder: How I do it
Technical Points:  Female Cystectomy
Urethral Rhabdosphincter (EUS)
Mid to caudal urethra
Not removed with proximal urethrectomy
No sphincter is present at BN
Urethral Epithelium
Squamous epithelium in distal third
Transitional epithelium in proximal third
Epithelium merge in middle third
Neobladder: How I do it
Technical Points:  Female Cystectomy
Urethral Innervation
Urethral innervation along lateral vaginal wall and BN
Minimize LND in area of hypogastric n. plexus
Post cystectomy innervation contributes to continence
Tonic neural discharge to EUS at all times increases with bladder filling
Neobladder: How I do it
Technical points:  Female Cystectomy
Neobladder: How I do it
Technical points:  Female Cystectomy
Neobladder: How I do it
Technical Points:  Why the Hautmann ?
Good functional outcomes
Large capacity
Simple to construct
No foreign bodies/nipples
Easy to adapt to anatomical variations
Easy to revise if problems arise
Neobladder: How I do it
Technical Points:  Modified Hautmann
Urethral Tubularization (Hautmann)
Anastomotic tension no longer a problem
Facilitates future urethrectomy if necessary
Contributes to continence ?
Neobladder: How I do it
Technical Points:  Modified Hautmann
Chimney Modification (Theodorescu)
Facilitates ureteroileal anastomosis
Easily adaptable for short ureters (L or R)
Permits easy revision/resection of anastomosis
