Botox helps ease symptoms of enlarged prostate according to Univ. of Pittsburgh study

SAN FRANCISCO, May 11 Injections of botulinum toxin A (botox) into the prostate are a promising alternative treatment for the millions of men who have benign prostatic hyperplasia (BPH), a condition commonly referred to as enlarged prostate, according to a study conducted by the University of Pittsburgh School of Medicine and Chang Gung Memorial Hospital in Taiwan.

Three to seven days post-injection the patients showed a decrease in irritative symptoms as indicated by a reduction in the international prostate symptom score by 62.3 percent and improvement in the quality of life index by 56.5 percent. Patients also experienced a significant increase in flow rate, and a small decrease in residual urine and prostate size.

Patients did not experience any significant side effects including stress urinary incontinence, retrograde ejaculation or erectile dysfunction.
