Brief Summary:
This is a prospective, randomized study of two types of continent ileal neobladder construction in patients undergoing cystectomy for primary bladder cancer. Patients will be randomly assigned to have either a T-pouch or a Studer pouch constructed at the time of their surgery. They will be followed long-term to determine the relative advantages and disadvantages of the two types of diversion. The investigators' hypothesis is that the inclusion of an antireflux mechanism in the T-pouch will result in significantly fewer episodes of symptomatic urinary tract infection, and will have a lower incidence of upper tract dilation and loss of renal function over the long term.

Primary Outcome Measures :
  1. The primary endpoint is the long-term outcome (> 3 years) as it pertains to renal function, anatomy of the upper urinary tracts, and the requirement for medical or surgical intervention (ie for symptomatic urinary tract infections). [ Time Frame: 3 years after date of last patient enrolled ]

Secondary Outcome Measures :
  1. A secondary endpoint is the length of surgery and the incidence of early postoperative complications (<30 days from surgery) believed to be related to the type of urinary diversion. [ Time Frame: Within 30 days after surgery ]
  2. An additional secondary endpoint is cancer recurrence and overall survival, which will be recorded in each patient. [ Time Frame: Yearly for the first 5 years, then every 2 years ]

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • All patients undergoing radical cystectomy for bladder cancer who are considered candidates for a neobladder reconstruction are eligible for enrollment.
  • Diagnosed with primary bladder cancer (any histology).
  • Scheduled to undergo a radical cystectomy (cystoprostatectomy in men and anterior exenteration in women).
  • Felt by the treating physician to be a candidate for an orthotopic neobladder urinary diversion.
  • Be competent and willing to sign the informed consent.
  • Patients may have received previous radiation therapy or intravesical or systemic chemotherapy. Patients with documented metastatic disease are not excluded as long as they are felt to be candidates for a continent neobladder urinary diversion.

Exclusion Criteria:

  • Patients undergoing radical cystectomy for any malignancy other than primary bladder cancer (for example prostate cancer or colon cancer invading the bladder,or a gynecologic malignancy), or non-malignant disease (such as a neurogenic bladder or radiation cystitis).
  • Unwilling or unable to sign the informed consent.
  • Not eligible for an orthotopic neobladder reconstruction.
  • A history of other malignancy (except for stage I cancer treated with curative intent without evidence of recurrence, clinically localized prostate cancer either untreated or treated with prostatectomy or radiation therapy or hormone therapy,or non-melanoma skin cancer) within the previous 5 years.
