A Comparison of the Studer Pouch Versus the T-Pouch Orthotopic Neobladder Urinary Diversion in Bladder Cancer Patients

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.
