ANAHEIM, Calif., May 21, 2007 — Women with stress urinary incontinence (SUI) treated using muscle-derived stem cell injections to strengthen their sphincter muscles experience long-term improvements in their condition, according to a study led by researchers at the University of Pittsburgh School of Medicine and Sunnybrook Health Sciences Centre in Toronto. The study, which followed patients for more than one year, suggests that the approach is safe, improves patients’ quality of life and may be an effective treatment for SUI. The findings will be presented at the Tissue Engineering and Regenerative Medicine in Urology press briefing at the annual meeting of the American Urological Association (AUA) in San Diego, and will be published in Abstract 1331 in the AUA proceedings.
