Eligibility

Inclusion Criteria:

• Female patients aged = 18 years with urological indications (OAB, UUI, UFS, retention syndromes and pain)
• Meeting criteria for routine SNM (primary or revision surgery) at the discretion of their normal care urologist.
• Ability and willingness to give informed consent
• Willingness to stay overnight in hospital after SNM procedure (as per routine care)

Exclusion Criteria:

• Patient is pregnant, breastfeeding, or plans to become pregnant during the course of the study (pregnancy tests provided in schedule) [this is an exclusion for SNM in any case]
• Any significant medical condition that is likely to interfere with study procedures, device operation, or likely to confound evaluation of study endpoints
• Any psychiatric or personality disorder at the discretion of the study physician
• Any neurological condition that may interfere with normal bladder function (e.g., stroke, multiple sclerosis, Parkinson's disease; clinically significant peripheral neuropathy, or complete spinal cord injury)
• Patient has uncontrolled type I or type II diabetes as defined by their routine care clinician or diabetes with peripheral nerve involvement
• Patient has history of other non-pelvic neoplasia within 5 years prior to enrolment, except for a cancer that was determined to be local occurrence only, such as basal cell carcinoma, or is receiving or planning to receive anti-cancer or anti-angiogenic drugs
• Patient has proven major autoimmune disease, e.g. scleroderma or immunodeficiency (including use of biologic immunomodulatory drugs at time of procedure)
• Patient is not suitable for the study as determined by their routine care physician for any other reason
• Patient is enrolled in another interventional study excepting observational studies, e.g. SNM registries or in relation to disease (see below)
• Patient participation in vigorous sporting activities where these cannot be restricted for a period of 24h while the extracorporeal lead is in situ. Specific urological
• As per routine clinical SNM criteria (see: https://www.nice.org.uk/guidance/ipg6434) Specific technical
• Patient is significantly obese (defined as BMI = 35) so as to limit electrode lead placement using standard approaches
• Skin, orthopaedic or neurological anatomical limitations that could prevent successful placement of the electrode lead
• Subject with a documented history of allergic response to titanium, zirconia, polyurethane, epoxy, or silicone
