Quelles peuvent être les futures applications de la toxine botulique en urologie en dehors des vessies hyperactives des patients neurologiques ? What are the future possible uses of botulic toxin in urology besides in the treatment of hyperactive bladders in neurological patients?

Botulinum toxin (BT) is used in urology and neurourology since the end of the 80 s. Its ease of use and some promising results incite to try it in numerous indications. Treatment of neurogenic detrusor hyperactivity with BT is considered valid. There are clinical studies of high level of evidence for treatment of idiopathic overactive bladder symptoms and detrusor-spincter dyssynergia, but it is not considered valid yet, because inclusion criteria and adverse effects are not perfectly estimated. Evalu- ations of other indications (benign prostatic hyperplasia for example) are there still at their beginning. Two molecules are marketed in France, without comparison studies. Clinical studies are still mandatory in order to clarify posology, modality of injection and therapeutic strategy.
