Urogynecologic Condition

Overactive Bladder.

Overactive bladder (OAB) is a syndrome — not a single condition — defined by urinary urgency, frequency, and sometimes leakage. The bladder muscle contracts when it should be resting. The result: a sudden, hard-to-defer urge to urinate, often with little warning.

It is extraordinarily common — affecting an estimated 33 million Americans — and frequently dismissed as “just a small bladder.” It is not. It is a treatable medical condition, and there is a tiered, well-studied set of treatments that resolves it for the vast majority of patients.

If you've noticed any of these, it's worth a conversation.

Most patients tell us they assumed the symptom was minor — or just something they would have to live with. Neither is usually true.

  • Sudden, strong urges to urinate — sometimes with no warning
  • Urinating more than eight times per day
  • Waking two or more times overnight to urinate
  • Leakage on the way to the bathroom (urge incontinence)
  • Avoiding outings, exercise, or sleep because of bathroom anxiety
  • Triggers like running water, cold weather, or arriving home

Common causes & risk factors

  • Idiopathic — the most common scenario, no single identifiable cause
  • Neurologic conditions affecting bladder signaling
  • Prior pelvic surgery or radiation
  • Bladder irritants in diet (caffeine, alcohol, artificial sweeteners)
  • Hormonal changes after menopause
  • Coexisting pelvic floor dysfunction

Treatment Approach

Non-surgical first. Always.

Most patients with overactive bladder improve significantly with behavioral, physical, and minimally invasive treatments — long before surgery enters the conversation. Here is the full toolbox, in the order we typically work through it.

Non-surgical options

Bladder retraining & timed voiding
Structured retraining of the urge-void cycle. Done well — and supervised — this resolves a significant percentage of cases without medication.
Dietary & behavioral modification
Identifying and reducing bladder irritants. Fluid timing. Pelvic floor coordination. Boring on paper, transformative in practice.
Pelvic floor physical therapy
Particularly for patients whose OAB coexists with pelvic floor tension or dysfunction — which is more common than most patients realize.
Anticholinergic & β3-agonist medications
Two well-studied medication classes for OAB. Discussed honestly, including side effects and what to expect. We don't push pills; we offer them when the timing is right.
Percutaneous tibial nerve stimulation (PTNS)
A 30-minute office treatment that quietly calms bladder signaling. Twelve weekly sessions. Effective, reversible, no medication required.
Bladder Botox
Office-based injection that reduces bladder muscle overactivity for six to nine months at a time. Excellent outcomes in patients who have failed medications.

Surgical options When non-surgical care isn't enough

Surgery is one tool in a much larger toolbox. When we do recommend a procedure, it is because we have a specific reason — and we will explain exactly what it does, what it doesn't do, and what recovery actually looks like.

Sacral neuromodulation
An implanted nerve stimulator for patients with severe, refractory OAB. Tested first with a temporary lead — so you know whether it works for you before anything permanent is placed.

  3. 03

    In-office diagnostics if needed

    Diagnostics are performed in-office where possible to avoid extra appointments.

  4. 04

    Your written plan

    Every option explained. Pros, cons, and what each one would mean for your week, your work, and your life.

A Patient Story

I was waking up four times a night and planning every meeting around the nearest bathroom. Two months of behavioral retraining and one medication later, I sleep through the night. I wish I had brought it up ten years earlier.

Frequently Asked

Overactive Bladder: the questions patients ask Dr. Johnson.

How is overactive bladder different from a small bladder?

A “small bladder” is rarely the actual issue. The bladder capacity is usually normal; the problem is that the bladder muscle contracts when it shouldn't, generating a sense of urgency long before the bladder is actually full. The difference matters because the treatments are entirely different — and effective.

— Lisa L. Johnson, M.D., U.R.P.S.

Are OAB medications safe long-term?

The β3-agonist class has an excellent long-term safety profile and is my usual first-line medication choice. Older anticholinergics have a more nuanced profile — particularly in older adults — and we make those decisions with care. I will not put you on a medication you don't need, and I will not keep you on one that isn't working.

— Lisa L. Johnson, M.D., U.R.P.S.

Does bladder Botox actually work?

Yes — in the right patients, very well. It is an in-office procedure, takes about ten minutes, lasts six to nine months, and is one of the most reliable treatments I have for medication-refractory urge incontinence. We discuss the small risks (temporary need for self-catheterization in a minority of patients) openly before deciding.

— Lisa L. Johnson, M.D., U.R.P.S.

Will cutting caffeine actually help?

For many patients, dramatically. Caffeine, carbonation, citrus, and artificial sweeteners are the most common dietary contributors. I never ask anyone to give all of them up forever — but a structured elimination and reintroduction usually identifies the one or two that matter most to your specific bladder.

— Lisa L. Johnson, M.D., U.R.P.S.

Is there a cure?

I would rather say durable resolution than cure. Most of my OAB patients reach a point where symptoms are minimal and self-managed with a combination of habits and, where needed, one tool from the toolbox. The goal is not to depend on medication forever — and for most patients, we don't.

— Lisa L. Johnson, M.D., U.R.P.S.
