Study type | Observational |
This is a prospective cohort study of women with overactive bladder OAB (dry or wet) who have failed 2 prior treatments, including behavioral modification, pelvic floor physical therapy, and/or OAB medication (anticholinergics or mirabegron), and have chosen either OnabotulinumtoxinA (BTX) injection or percutaneous tibial nerve stimulation (PTNS) as their next treatment. OAB-dry refers to patients with OAB who do not have urge urinary incontinence; OAB-wet refers to patients with OAB and urge urinary incontinence. Eligible patients will be approached for study participation after they have decided to proceed with BTX or PTNS.

Eligibility |
Inclusion Criteria: 1. Women with refractory OAB (dry or wet) 2. OAB will be defined by a positive response and bother of "somewhat, quite a bit, a great deal, or a very great deal" to question #3 or #8 on the OAB-q (see appendix B) regarding urinary urgency and urgency incontinence. 3. Refractory will be defined as failure of 2 prior treatments, including behavioral modification, pelvic floor physical therapy, and OAB medication (anticholinergics or mirabegron). Trial of 2 medications that did not improve symptoms after 2 weeks or could not be tolerated due to side effects will constitute 2 treatment failures. 4. Women with mixed urinary incontinence that is urge predominant will also be included. 5. Age = 18 years 6. English speaking 7. Available for 1 year follow-up 8. Able to complete study questionnaires Exclusion Criteria: 1. Neurologic disease known to cause OAB including, but not limited to, Multiple sclerosis, Parkinson's disease, and Spinal Cord Injury. 2. Pregnancy by self-report or pregnancy test 3. Contraindication to PTNS and/or BTX - PTNS: Pacemaker - BTX: myasthenia gravis, allergy to BTX, urinary retention (post void residual >200cc) 4. Planned surgery for pelvic floor disorder during the study period 5. Prior treatment with BTX, PTNS, or sacral nerve stimulation (SNS) for refractory OAB/urinary urge incontinence (UUI) |

Primary | Difference in patient global impression of improvement score between PTNS and BTX groups | The Patient Global Impression of Improvement (PGI-I) is a single question that asks a patient to rate her urinary symptom response to treatment on a 7-point Likert scaleis a validated questionnaire for assessment of the impact of OAB on patient's lives. | 3 month | |
Primary | Change in quality of life between PTNS and BTX groups | The minimally important difference (MID) for change in SSS is 10 points. We compare the change in SS score between the PTNS and Botox groups at 3 months. | 3 month | |
Secondary | Change in individual question scores on OAB-q questionnaire | The OAB-q consists of 33 items: an 8-item symptom bother scale (SS) and a 25-item health-related quality of life (HRQL) scale. Higher scores on HRQL scale represent better quality of life and lower scores on SSS is indicative of less bother. | 3 | |
Secondary | Change in urinary symptom severity | Tools used: Urogenital Distress Inventory short form (UDI-6) is a validated questionnaires used to assess urinary symptoms. We will compare change in scores between the 2 groups | 3 |
