A Randomized Comparison of the Studer Pouch vs. the T-Pouch Orthotopic Neobladder Urinary Diversion in Bladder Cancer Patients
Abstract
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.
Conditions: Bladder Cancer.
Primary outcome: 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)..
Enrollment: 529 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 529 participants or records.
