実験的:OAB
Patients with overactive bladder (OAB) with or without urge incontinence. Two patient populations will be enrolled in the study: Patients with no previous treatment with percutaneous tibial nerve stimulation (PTNS) [de novo patient group] and Patients with a documented success on PTNS therapy [prior-PTNS group]. Documented success on PTNS is defined by a ≥50% reduction in urinary frequency, and/or ≥50% fewer incontinence episodes, or a return to normal voiding frequency [<8 voids/day], based on retrospective diary review. All patients will be treated with BlueWind Medical System. |
The BlueWind Medical System is intended for the treatment of patients with overactive bladder (OAB) including urinary urgency frequency and urge incontinence.
