Plain English summary of protocol
Background and study aims
The aim of the study is to obtain long-term clinical data for the recharge-free Axonics F15 SNM System (also referred to as INS Model 4101).
Who can participate?
Adults aged 18 or older, previously diagnosed with urinary urge incontinence (UUI) with or without urinary frequency (UF) and/or chronic fecal incontinence (FI), who received the Axonics F15 SNM System device and who have baseline bladder or bowel diaries.
What does the study involve?
The study involves a retrospective chart review of all F15 implants that took place ≥1-year post-implant, at selected centers. In addition, patients who have baseline bladder or bowel diaries will be prospectively enrolled and will complete one follow-up visit. The follow-up visit entails completing a post-operative bladder or bowel diary and a patient satisfaction questionnaire.
What are the possible benefits and risks of participating?
Benefit: The study will help gather long-term data on the recharge-free Axonics F15 SNM System (also referred to as INS Model 4101).
Risks: Similar to any sacral neuromodulation device indicated for overactive bladder disease and fecal incontinence.

| Study objectives | To obtain long-term clinical data for the recharge free Axonics F15 SNM System (also referred to as INS Model 4101). |
| Ethics approval(s) | Ethics approval not required |
| Ethics approval additional information | The study is a data collection effort whereby data is being collected retrospectively from those patients who were implanted with the Axonics SNM F15 device who are ≥ 1-year post-implant and who have baseline bladder or bowel diaries. Please note the device has been approved by the Food and Drug Administration (FDA) in the United States and Canada in 2022 and recently approved by the Therapeutic Goods Administration (TGA) in Australia in 2024. |
| Health condition(s) or problem(s) studied | Urinary urge incontinence (UUI) with or without urinary frequency (UF) and/or chronic fecal incontinence (FI) |
| Intervention | Multicenter, prospective study comparing bladder or bowel diaries at baseline to a minimum of 1 year follow up and up to 2 years if the participant is eligible (i.e., participants implanted between March‐July 2022). Participants will be identified through a retrospective chart review of all patients at the selected sites who were implanted with the Axonics F15 SNM and who have baseline bladder or bowel diaries. Device parameters and safety data will be collected, and a patient satisfaction questionnaire will be administered at the follow‐up visit. |
