Outcomes

Primary Outcome Measures

Success rate
"Success" is defined as a >= 50% improvement in at least one of the following symtoms: pollakiuria, number of urge incontinence episodes with incontinence, number of urge incontinence episodes.

Secondary Outcome Measures

presence/absence: 50% reduction in the number of daily mictions
presence/absence: 50% reduction in the number of pads/protections used per day
presence/absence: 50% reduction in the number of urge incontinence episodes per day
presence/absence: 50% reduction in the number of urge incontinence episodes with incontinence per day
Symptom severity as measured by the MHU score
MHU = Mesure Hanicap Urinaire
Yes/no: the patient was eligible for an implant
debimetry: flow rate per voiding
debimetry: urinary volume per voiding
Visual analog scale for pain at the implantation site
Visual analog scale for pain due to neuro stimulation (pain in legs or buttocks)
Presence/absence of infection of the implant or electrode
Change in quality of life: IQoL score
Change in quality of life: KHQ score
Change in quality of life: SF 36 score

5. Study Description

Brief Summary
The primary objective of this study is to compare the efficacy of unilateral and bilateral neuromodulation tests at 1 month.
Detailed Description
The secondary objectives of this study are to compare the following elements between a group of patients undergoing unilater modulation tests (standard procedure) and a group of patients undergoing bilateral neuromodulation tests (experimental procedure) (at 1 month): Pollakiuria, pad use, urge incontinence, symptom severity, % of patients not eligible for an implant, debimetry, tolerance, complications, quality of life.

8. Arms, Groups, and Interventions

Arm Title
Unilateral testing
Arm Type
Active Comparator
Arm Description
Following standard procedures, patients in this group will have unilateral testing for neuromodulation of the sacral nerves. Intervention: Unilateral electrode placement and testing
Arm Title
Bilateral testing
Arm Type
Experimental
Arm Description
Patients in this group will have bilateral testing for neuromodulation of the sacral nerves. Intervention: Bilateral electrode placement and testing
Intervention Type
Procedure
Intervention Name(s)
Unilateral electrode placement and testing
Intervention Description
An electrode is placed near a sacral nerve with an anal motor response under general anesthesia. During and adjustment phase, the electode is connected to a test box which allows for adjustment of stimulation parameters. After pinpointing stimulation parameters, the external test box is replaced by an implanted device.
Intervention Type
Procedure
Intervention Name(s)
Bilateral electrode placement and testing
Intervention Description
Two electrodes are placed, one near each sacral nerve under general anesthesia. During an adjustment phase, the electodes are connected to a test box which allows for adjustment of stimulation parameters. This can result in the use of one or the other, or both electrodes, thus increasing the chances of success and the possibility that the patient is eligible for an implant. After pinpointing stimulation parameters, the external test box is replaced by an implanted device.
