Direct Full-stage Implantation of Sacral Neuromodulation

The purpose of this investigator-initiated study is to investigate the efficacy and costs of direct full stage sacral neuromodulation in patients with overactive bladder. Patients with refractory OAB and urge urinary incontinence will undergo direct full stage implantation and be followed for a period of 6 months to monitor symptom improvement with voiding diaries and validated questionnaires preoperatively and postoperatively. Therapeutic and adverse outcomes will be evaluated. The use of medical resources and time off of work will be analyzed as well. This will be a descriptive study with no additional arms or randomization.
