Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Experimental Cyclic SNM |
Programming of the SNM device will occur as per standard protocol in discussion between patient and SNM representative. The intervention will be to set the device to cycling stimulation program mode. |
|
|
Active Comparator Continuous SNM |
Programming of the SNM device will occur as per standard protocol in discussion between patient and SNM representative. The intervention will be to set the device to continuous stimulation programming (SNM is continuously stimulating without "off" periods) |

Detailed Description
Overactive bladder (OAB) is characterized by urinary frequency, urgency, incontinence, and nocturia in the absence of other pathology. AUA guidelines recommend trial of sacral neuromodulation (SNM) for patients with refractory OAB who have failed treatment with behavioral modification and medication. SNM settings are typically selected based on discussion between the patient and device representative. There is a paucity of rigorous data assessing optimal SNM stimulation programming for symptomatic improvement. This will be a prospective, randomized-controlled multi-site trial comparing cyclic versus continuous sacral neuromodulation (SNM) in patients undergoing SNM for OAB. Patients > age 18 with a diagnosis of refractory OAB being scheduled for a trial of SNM (either stage I lead/temporary battery placement or office peripheral nerve evaluation) will be approached by study personnel during their clinic visit or by a phone call to determine if they are interested in participating in the programming study. Patients interested in participating will provide written informed consent. After informed consent is obtained, a baseline evaluation will be performed. This includes history, 3-day voiding diary (# voiding episodes, # nocturia episodes, # urge incontinence episodes/24h), urinalysis, urine culture (if indicated), post void residuals, and symptom assessments using questionnaires. Only those with successful trial and eligible/ interested in permanent SNM placement will participate in this trial. Randomization will occur after stage 2/ full permanent implantation when the neuromodulator is being programmed in the recovery room. Patients will be randomly assigned to either continuous stimulation or cyclic stimulation. Patients will then be followed with clinical evaluation and questionnaires repeated at 1 month, 6 months, 12 months, 3 years, and 5 years post-op.
