"Millions of men in the United States suffer from enlarged prostate," said Michael B. Chancellor, M.D., professor of urology and gynecology at the University of Pittsburgh School of Medicine. "It's a challenging disease to live with because it causes frequent and difficult urination. Unfortunately, common treatments also are problematic because they carry some risk of serious side effects, such as impotence. Our results are encouraging because they indicate that Botox could represent a simple, safe and effective treatment for enlarged prostate."
The patients, ranging in age from 49 to 79 years, with symptomatic BPH that did not respond to standard medical treatment, received injections of Botox directly into their prostate glands. Thirty-one patients, or 75.6 percent, experienced a 30 percent improvement in urinary tract symptoms and quality of life. These improvements were seen up to one year post-injection in some of the patients. Four out of five patients, or 80 percent, were able to completely empty their bladders within a week to one month after the injection, as the Botox caused the prostate gland to relax, putting less pressure on the urethra.
