Study Details

Study Description

Brief Summary

Prospective, randomized, placebo-controlled, double-blind multicenter trial including 4 tertiary sacral neuromodulation referral centers in Switzerland (Zürich, Bern, Nottwil, St.Gallen). Patients with refractory neurogenic LUTD are included and randomized after neuromodulator implantation into sacral neuromodulation ON or sacral neuromodulation OFF (n=30) for a 2 months double-blind phase. In addition to standard neuro-urological assessments, patients who agree will also undergo neurophysiological investigation of the lower urinary tract, i.e. recording of current perception thresholds, sensory evoked potentials, and electroencephalography after stimulation of the urethra and bladder.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: sacral neuromodulation ON

active sacral neuromodulation (neuromodulator ON)

Device: Turning ON the neuromodulator

Placebo Comparator: sacral neuromodulation OFF

placebo sacral neuromodulation (neuromodulator OFF)

Device: Turning OFF the neuromodulator
Turning OFF the neuromodulator in 50% of the patients in a randomized way by an investigator not involved in the assessment of the clinical outcome during the regular outpatient visit 2 months after neuromodulator implantation. It then follows a 2 months double-blind phase. Thereafter, i.e. during the regular outpatient visit 4 months after neuromodulator implantation, the unblinding takes place and in patients with sacral neuromodulation OFF, the neuromodulator is switched ON.

Outcome Measures

Primary Outcome Measures

  1. Number of patients with successful sacral neuromodulation [2 months]
