In the largest and most rigorous U.S. trial comparing two traditional operations for stress urinary incontinence (SUI) in women, a team of urologists and urogynecologists supported by the National Institutes of Health (NIH) has found that a sling procedure helps more women achieve dryness than the Burch technique. The study is being released early by the New England Journal of Medicine (NEJM) to coincide with a presentation at the annual meeting of the American Urological Association on May 21, 2007. Results will appear in the May 24 print edition of NEJM.
