[Sacral root neuromodulation for the treatment of urinary incontinence reported to detrusor hyperactivity]. / Traitement de l'incontinence urinaire secondaire à une hyperactivité vésicale par neuromodulation sacrée.

BACKGROUND AND PURPOSE: This paper reviews therapeutic sacral neuromodulation for treating urinary urge incontinence related to detrusor hyperactivity. METHODS: We reported data from our department and from the international literature on topics such as the physiological basis of neuromodulation, techniques of testing, chronic implantation and clinical results. RESULTS: In an intention to treat analysis , neuromodulation results varied from 21.5 to 25% globally. On implanted patients, the response rate varied from 40 to 88% and was stable. Sub-chronic test morbidity was very rare. Surgical revision rate was reported from 6.25 to 37.7%. CONCLUSIONS: Neuromodulation strongly ameliorates approximately a third of all the patients with urge urinary incontinence due to detrusor hyperactivity. New technical improvements should lead to better results in the future.
