Efficacy and Safety of Botulinum Toxin A for the Treatment of Refractory Overactive Bladder.

Summary

Overactive bladder induce urgency, urge incontinence, nocturia and pollakiuria. This condition is often resistant to anticholinergic drugs used as a first line treatment for this purpose. Moreover muscarinic side effects (constipation, mouth dryness) often limits the use of those treatments. This study is designed to evaluate the efficacy and safety of botulinum toxin A injected into the detrusor muscle to control symptoms and improve quality of life for patients resistant or intolerant to anticholinergic drugs.
