Pelvic Health Electrically Evoked Recording (PEER) 2 Study

To collect physiological signals at several timepoints during the therapy evaluation period.

This clinical trial information was submitted voluntarily under the applicable law and, therefore, certain submission deadlines may not apply. (That is, clinical trial information for this non-applicable clinical trial was submitted under section 402(j)(4)(A) of the Public Health Service Act and 42 CFR 11.60 and is not subject to the deadlines established by sections 402(j)(2) and (3) of the Public Health Service Act or 42 CFR 11.24 and 11.44.)

Eligibility Criteria:
Inclusion Criteria:

Overactive Bladder Criteria Inclusion Criteria

1. 18 years of age or older
2. Candidate for or undergoing Medtronic InterStim lead implant for labeled indication\* requiring an advanced evaluation
3. Willing and able to provide signed and dated informed consent
4. Willing and able to independently and accurately complete diaries, questionnaires, attend visits, and comply with the study protocol
5. Willing to maintain current regimen (dosage and frequency) of any OAB medication from baseline diary through the end of therapy evaluation
6. For subjects with urinary urge incontinence, have a diagnosis of OAB as demonstrated on a voiding diary by having a minimum of 3 episodes of urinary urge incontinence in the first 72 hours (Episodes must have a mild, moderate, or severe degree of urgency to meet this criterion) of the voiding diary.
7. For subjects with urinary frequency, have a diagnosis of OAB as demonstrated on a voiding diary with greater than or equal to 8 urgency frequency episodes per day within the first 72 hours of the voiding diary.

Note\*: Candidate for or undergoing a Medtronic InterStim lead implant for labeled indication means that a clinical decision has already been made between a physician and the patient to undergo Medtronic Interstim lead implant to treat the subject's condition. This decision is to be made prior to discussing with the patient whether to enroll in the study.

Non-Obstructive Urinary Retention Inclusion Criteria

1. 18 years of age or older
2. Candidate for or undergoing Medtronic InterStim lead implant for labeled indication\* requiring an advanced evaluation
3. Willing and able to provide signed and dated informed consent
4. Willing and able to independently and accurately complete diaries, questionnaires, attend visits, and comply with the study protocol
5. Willing to maintain current regimen (dosage and frequency) of any NOUR medication from baseline diary through the end of therapy evaluation
6. Have a diagnosis of non-obstructive urinary retention as demonstrated by a urinary voiding diary with a minimum of 5 clean intermittent self-catheterizations in a 7-day period; and chronic non-obstructive urinary retention with an elevated postvoid residual (PVR) that has persisted for at least six months and is documented on two or more separate occasions.

Note\*: Candidate for or undergoing a Medtronic InterStim lead implant for labeled indication means that a clinical decision has already been made between a physician and the patient to undergo Medtronic Interstim lead implant to treat the subject's condition. This decision is to be made prior to discussing with the patient whether to enroll in the study.

Fecal Incontinence Inclusion Criteria

1. 18 years of age or older
2. Candidate for or undergoing Medtronic InterStim lead implant labeled indication\* requiring an advanced evaluation
3. Willing and able to provide signed and dated informed consent
4. Willing and able to independently and accurately complete diaries, questionnaires, attend visits, and comply with the study protocol
5. Willing to maintain current regimen (dosage and frequency) of any FI medication from baseline diary through the end of therapy evaluation
6. Have a diagnosis of fecal incontinence as demonstrated by a bowel diary as greater than or equal to 2 incontinent episodes of more than staining (i.e., either slight, moderate, or severe soiling) per week

Note\*: Candidate for or undergoing a Medtronic InterStim lead implant for labeled indication means that a clinical decision has already been made between a physician and the patient to undergo Medtronic Interstim lead implant to treat the subject's condition. This decision is to be made prior to discussing with the patient whether to enroll in the study.
