Sondra Barker, CRNP asks every new patient the same first question: how long have you had these symptoms? The answer is usually five years or more. Barker is a board-certified women’s health nurse practitioner in urogynecology at Ascension Saint Agnes in Baltimore, with more than two decades in women’s health. In this episode of the VNEW Health Podcast, host Robert Greer works through overactive bladder with her end to end, from why women wait to what every treatment tier actually involves.
Key Takeaways From Sondra Barker, CRNP
- Patients present after an average of five years or more of symptoms
- The tipping point is lost sleep, then a shrinking social life
- Overactive bladder is a combination of up to four symptoms, not just leakage
- A 24-hour bladder diary produces more usable information than an exam alone
- Symptoms that look like overactive bladder sometimes originate in sleep apnea or diabetes
- Medications work roughly 75 to 85 percent of the time and need six weeks to judge
- Third-line therapies have no required order; the choice is what fits the patient’s life
- No age disqualifies a patient from any of these treatments
Why Women Wait Five Years
Barker says the delay is usually because of factors outside of symptoms and their severity. Embarrassment, acceptance, and believing it will get better on its own are common reasons women wait to see a doctor. It is often not until they start losing sleep or stop feeling able to go places that they come in. Barker also says cost is also an issue. Pad and absorbent underwear are a running expense, and it still can be difficult to manage even with insurance or available discounts
Signs of an Overactive Bladder
Barker explains overactive bladder as a combination of symptoms. The number can range from one to four depending on the patient and can include how often a patient goes during the day, how many times they get up at night, urgency, and leakage.
She grades urgency and leakage on a four-point scale. A “four” is the most severe, when a patient is racing to the bathroom and leaking on the way. Barker names leakage as the second biggest issue reported by patients, after sleep loss
Overactive Bladder vs. Urinary Incontinence
An overactive bladder and urinary incontinence are not the same thing and Barker indicates this is a clinically important distinction. An overactive bladder can occur with no leakage at all. There are also patients who have more than one condition contributing to an overactive bladder. Bladder prolapse and overactive bladder may be two separate problems, but Barker notes they are sometimes related and both have to be assessed.
She makes the broader point that symptoms which present as overactive bladder do not always originate in the bladder. Sleep apnea can cause patients to wake up with a need to urinate, and poorly controlled diabetes needs to be addressed before relying on bladder treatment.
What Is a Bladder Diary?
A bladder diary is a written 24-hour log of bladder activity, and Barker asks nearly every patient to complete one before deciding anything.
She outlines her protocol:
- Start at 8:00 in the morning and run through to 8:00 the next morning
- Write down every time you urinate
- Write down every leak
- Record how many pads you changed
- Record how strong the urge was each time
- Record what you drank and how much
This 24-hour protocol gives her what an exam cannot. It exposes whether a patient is holding until the last minute, whether they are going too often and never letting the bladder fill, and what they are actually drinking.
What Causes an Overactive Bladder?
Barker says there is rarely just one cause. The following can all contribute:
- Pelvic floor muscle tone
- Menopause and estrogen loss
- Childbirth
- Other health conditions
- Medications
- Bladder training gone wrong
She adds that she has seen primary care respond by prescribing a single medication, and when it fails the patient concludes no medication will work and never hears about third-line therapies at all.
Urodynamics Testing
When symptoms are unclear after a bladder diary, Barker uses a urodynamics test to evaluate how the bladder fills, stores, and empties. The test pinpoints whether the problem is related to the bladder muscle, pelvic floor, a prolapse, the urethra, or nerve sensitivity. Showing both muscle contractions and bladder capacity helps Barker choose the best treatment path, whether that means medication, physical therapy, or third-line options.
Treatment Options for Overactive Bladder
Barker works through the tiers in order, with one important qualification: within third-line therapy, there is no required sequence.
First Line: Medication for Overactive Bladder
Barker prefers patients to have already tried and failed a medication, as insurers usually require trying one or two standard options before approving advanced treatments. These medications work for about 75 to 85 percent of patients.
Patients must stay on any bladder medication for at least six weeks to judge its effectiveness. To get treatments covered, Barker uses a detailed template letter outlining a patient’s history with behavioral changes, physical therapy, and previous medications.
Barker divides the main medications into two categories: anticholinergics and beta-3 agonists.
Anticholinergics are usually tried first, but Barker avoids prescribing it to women over 65 due to age-related organ decline and risks of cognitive fog or memory issues.
Beta-3 agonists are safe for women over 65, avoid cognitive risks, and cause fewer issues with dry mouth or constipation, though it has other potential side effects. Coverage is improving, especially with Medicare, though some plans still require patients to fail an older medication first.
Second Line: Pelvic Floor Physical Therapy and Home Devices
Barker frames this tier as both a treatment and a holding position. She says pelvic floor physical therapy and home devices do help, and they buy you time if you are not ready to move on or cannot commit to third-line therapy.
Pelvic floor physical therapy involves specialized, one-on-one care focused on incontinence. Therapists use external and internal techniques, biofeedback, targeted exercises, diet reviews, and bathroom scheduling. Barker’s office maintains close communication with these specialists to coordinate care throughout the process.
For home devices, Barker emphasizes that feedback is essential. Without a device that shows whether muscles are engaging properly, patients risk performing exercises incorrectly and missing out on results
Third Line: Tibial Nerve Stimulation
Barker introduces the third line as three options in no particular order. A patient chooses what fits their lifestyle, what they are most comfortable with, and what they can commit to.
Tibial nerve stimulation uses a grounding plate on the foot and a thin needle near the inner ankle connected to a stimulator. Sending electrical signals up the tibial nerve to the nerves controlling the bladder helps relax an overactive bladder.
Sessions last 30 minutes once a week for 12 weeks, followed by monthly maintenance sessions every four to six weeks. Medicare covers it for three years, and Barker says other insurers follow Medicare’s lead here. Clinicians evaluate progress after six weeks and will discontinue the therapy if the patient sees no improvement.
Barker cites an 85% success rate for tibial nerve stimulation. Patients are told up front they need to commit, because it is the least invasive and most time consuming option. At a previous practice, she performed around 3,000 of these a year.
Third Line: Bladder Botox
Bladder Botox uses the same formula as cosmetic Botox to relax an overactive bladder muscle. This allows the bladder to hold more urine and reduces sudden, urgent trips to the bathroom. Results take about two weeks to kick in and typically last four to six months. Barker schedules repeat sessions based on when a patient notices symptoms returning, provided at least three months have passed between treatments.
Barker performs 90 percent of these procedures right in the office. The clinician inserts a thin camera catheter, fills the bladder with a bit of water, and delivers roughly ten quick injections into the back wall. The process takes about three minutes and patients report it feels like a fingernail pressing into the palm. Patients take preventive antibiotics to ward off infections and can empty their bladder immediately afterward. While hospital settings offer IV sedation, the clinical outcome is identical, and most patients eventually prefer the convenience of the office.
Barker checks the bladder two weeks after the procedure to ensure normal emptying. The primary risk is temporary urinary retention, where the muscle relaxes too much to push urine out. This affects roughly 4 percent of patients. Because Botox cannot be reversed, anyone who experiences retention must be willing to use a temporary catheter until the medication wears off over time.
Third Line: Sacral Neuromodulation
Sacral neuromodulation treats overactive bladder, urinary retention, and fecal incontinence, though a patient only needs one of these conditions to qualify.
The process begins with a ten-to-fourteen-day trial. While the patient is asleep, a thin lead is placed near the third sacral nerve in the lower back and connected to an external battery. Barker looks for a 50 percent reduction in symptoms, using detailed bladder diaries to confirm progress.
If the trial succeeds, a permanent battery is implanted under the skin of the upper buttock. Barker uses non-rechargeable devices with a 15-year battery life to avoid charging hassles for older patients. The device produces a gentle tapping or pulsating pressure between the tailbone and pelvis that calms the bladder.
Patients adjust settings using a small remote control, and Barker can make most programming changes over the phone. Annual checkups ensure the hardware remains functional.
When One Treatment Isn’t Enough
Barker focuses on layering treatment. If a patient isn’t progressing as they should, she reassesses and potentially restarts medication, adds Botox, or adds additional physical therapy.

FAQS
A written 24-hour log of bladder activity. Sondra Barker, CRNP asks patients to record from 8am to 8am: every time they urinate, every leak, how many pads they changed, how urgently they needed the bathroom, and what they drank and how much. She describes it as the single most informative thing a patient can bring to a first appointment, because it reveals habits and triggers that a physical exam cannot.
A test that measures what the bladder is doing as it fills, stores, and empties. Barker uses it to separate a bladder muscle problem from a pelvic floor problem, a prolapse problem, a urethral problem, or a sensory problem. She notes a bladder should typically hold roughly two to four cups before a strong urge, and that some patients register an urge at half a cup.
Two broad classes. Anticholinergics are the older group and are usually what insurance covers first. Beta-3 agonists are newer. Barker says medications work roughly 75 to 85 percent of the time, that any bladder medication needs a minimum of six weeks before its effect can be judged, and that she generally avoids anticholinergics in women over 65 because of side effects and cognitive effects. She notes anticholinergics are contraindicated in narrow-angle glaucoma.
A third-line treatment in which a thin needle is placed near the tibial nerve at the ankle and connected to a stimulator, sending a signal up to the sacral nerves that supply the bladder. Barker describes 30-minute sessions, weekly for 12 weeks, followed by maintenance every four to six weeks. She cites an 85 percent success rate across the board and calls it the least invasive third-line option and the most time consuming.
Barker compares it to cosmetic Botox: an overactive bladder muscle is contracting too tightly, and the injection relaxes it so the bladder can fill and store more before signalling urgency. She describes roughly nine or ten small injections into the back wall of the bladder, done through a camera, taking about three minutes in her office. It takes about two weeks to take effect and lasts three to nine months, with her patients averaging four to six.
A two-stage procedure. In the first stage a thin lead is placed at the third sacral nerve and connected to an external battery for a trial of roughly 10 to 14 days. Barker says the goal of the trial is 50 percent improvement in symptoms. If that threshold is met, a permanent battery is placed under the skin of the upper buttock in a second stage. She notes the device is also used for urinary retention and fecal incontinence.
Five years or more, according to Barker, who asks every new patient how long they have had symptoms. She attributes the delay to embarrassment, not wanting to accept it as aging, and believing it would resolve on its own. She says the tipping point is usually losing sleep, or beginning to decline invitations and make excuses not to go out.
No. Barker describes overactive bladder as a combination of symptoms, which may be one symptom or as many as four: frequency, waking at night, urgency, and leakage. Leakage is one possible component rather than the definition. She notes patients can have more than one condition contributing at once, and that symptoms which look like overactive bladder sometimes originate elsewhere, such as untreated sleep apnea or diabetes.
