[Tibial neuromodulation in the treatment of neurogenic detrusor hyperactivity in patients with Parkinson's disease].

Twenty nine patients with neurogenic detrusor overactivity due to Parkinson's disease have undergone percutaneous tibial neuromodulation. The treatment consisted of percutaneous insertion of a 34-gauge solid stainless steel needle at a point of 5 cm cephald from the medial malleolus. The patients were treated weekly for 30 minutes. A subjective effect was assessed using a dairy and I-PSS score. Objective results were evaluated by cystometry. We observed a decrease in the average voiding frequency, number of leakage episodes after 12 sessions and 6 months of the tibial neuromodulation. An over 50% symptomatic improvement was achieved in 26 of 29 patients including 6 patients who were refractory to anticholinergic agents and 9 men with benign prostatic hyperplasia. Tibial neuromodulation is an effective treatment in patients with neurogenic detrusor overactivity due to Parkinson's disease.
