What is the first step in managing a patient with overactive bladder?

First-Line Management for Overactive Bladder

Behavioral therapies should be offered as the first step in managing all patients with overactive bladder (OAB). 1

Initial Evaluation

Before initiating treatment, a proper evaluation should include:

• Medical history with comprehensive assessment of bladder symptoms 1
• Physical examination 1
• Urinalysis to exclude microhematuria and infection 1
• Post-void residual (PVR) measurement in patients with:
  • Concomitant emptying symptoms
  • History of urinary retention
  • Enlarged prostate
  • Neurologic disorders
  • Prior incontinence or prostate surgery
  • Long-standing diabetes 1

First-Line Treatment: Behavioral Therapies

Behavioral therapies offer several advantages:

• Excellent safety profile with few if any adverse effects 1
• No drug interactions or medication side effects 1
• Can be combined with other treatments later if needed 1

Specific behavioral interventions include:

• Bladder training - extensively studied with strong evidence of effectiveness 1, 2
• Fluid management - optimizing fluid intake throughout the day 1
• Caffeine reduction - limiting intake of bladder irritants 1, 2
• Physical activity/exercise - improves overall bladder function 1
• Dietary modifications - avoiding bladder irritants 1
• Urgency suppression techniques - methods to control sudden urges 1, 2
• Pelvic floor muscle training - strengthening exercises 2

Incontinence Management Strategies

For patients with urgency urinary incontinence, discuss management strategies:

• Absorbent products (pads, liners, protective underwear) 1
• Barrier creams to protect skin 1
• External collection devices when appropriate 1

Second-Line Treatment Options

If behavioral therapies alone are insufficient after an adequate trial:

• Pharmacologic therapy can be considered:
  • Beta-3 adrenergic agonists (e.g., mirabegron) 1, 3
  • Antimuscarinic medications 1
  • Note: Beta-3 agonists are typically preferred before antimuscarinics due to lower cognitive risk 1

Important Considerations

• Success of behavioral therapies depends heavily on patient acceptance, adherence, and compliance 1
• Most behavioral therapies require long-term patient compliance to maintain durable effects 1
• Patients should be counseled that nutraceuticals, vitamins, supplements, or herbal remedies have insufficient evidence to support their use 1
• Treatment should be chosen based on shared decision-making, considering the patient's values, preferences, and treatment goals 1

Treatment Algorithm

1. Start with behavioral therapies for all patients 1
2. If inadequate response after 8-12 weeks, add pharmacotherapy 4, 5
3. Consider combination approaches if monotherapy is insufficient 1
4. For refractory cases, refer for specialist evaluation for minimally invasive options 5

Common Pitfalls to Avoid

• Skipping straight to medication without trying behavioral approaches first 1
• Failing to rule out urinary tract infection or other pathology before diagnosis 1
• Not providing adequate education and support for behavioral interventions 6, 2
• Overlooking the importance of patient adherence to behavioral therapy 1
• Using antimuscarinic medications in patients with cognitive impairment risk 1
