What are the treatments for urinary frequency?

Treatment Options for Urinary Frequency

The first-line treatment for urinary frequency should be behavioral therapies including pelvic floor muscle training (PFMT), bladder training, and lifestyle modifications, followed by pharmacologic therapy with antimuscarinic medications or mirabegron if behavioral therapies are insufficient. 1

Diagnostic Considerations

Before initiating treatment, it's important to determine the underlying cause of urinary frequency:

• Overactive Bladder (OAB): Characterized by urinary urgency, usually with frequency and nocturia, with or without urgency incontinence 1
• Interstitial Cystitis/Bladder Pain Syndrome: Characterized by pain, pressure or discomfort perceived to be related to the bladder 1
• Urinary Tract Infection: Rule out with urinalysis and culture 2
• Stress Urinary Incontinence: Leakage with physical exertion 3

First-Line Treatment: Behavioral Therapies

1. Bladder Training:

   • Scheduled voiding with gradual extension of time between voids
   • Shown to improve continence with NNTB of 6 3

2. Pelvic Floor Muscle Training (PFMT):

   • 3 sets of 8-12 contractions daily, holding each for 6-8 seconds
   • Most effective behavioral intervention with NNTB of 3 3
   • Can be combined with biofeedback for better results

3. Lifestyle Modifications:

   • Weight loss for obese patients (improves UI with NNTB of 4) 3
   • Fluid management with 25% reduction in fluid intake 3
   • Caffeine reduction
   • Scheduled voiding

Second-Line Treatment: Pharmacologic Therapy

For patients with inadequate response to behavioral therapies after 8-12 weeks:

For Urgency-Related Frequency:

1. Antimuscarinic Medications:

   • Tolterodine: Better side effect profile than oxybutynin 4, 3
   • Solifenacin: Lowest risk for discontinuation due to adverse effects 3
   • Trospium: Lower incidence of constipation 3
   • Oxybutynin: Effective but higher incidence of dry mouth (71.4%) 3

2. Beta-3 Adrenergic Agonist:

   • Mirabegron: First-choice pharmacologic therapy for urge incontinence due to superior side effect profile 3

For Stress-Related Frequency:

• Duloxetine (SNRI): Reduces incontinence episodes by approximately 50% compared to placebo 3
• Vaginal estrogen: For postmenopausal women with mucosal atrophy (NNTB of 5) 3

Third-Line Treatment Options

For patients with refractory symptoms:

1. Sacral Neuromodulation (SNS): For severe refractory symptoms 3
2. Peripheral Tibial Nerve Stimulation (PTNS): Alternative third-line treatment 3
3. OnabotulinumtoxinA injections: Consider for severe refractory symptoms 3
4. Surgical interventions: For stress urinary incontinence after failure of conservative measures 3

Treatment Algorithm

1. Initial Assessment:

   • Confirm diagnosis with history, physical exam, urinalysis
   • Rule out UTI, neurological conditions, and other causes

2. First 4-8 Weeks:

   • Implement behavioral therapies (PFMT, bladder training)
   • Initiate lifestyle modifications

3. At 8-12 Weeks:

   • Evaluate response to behavioral therapies
   • If inadequate response, add pharmacologic therapy based on predominant symptoms

4. At 12-16 Weeks:

   • Reassess response to combined therapy
   • Consider referral for third-line treatments if inadequate response

Common Pitfalls to Avoid

• Misdiagnosing the type of incontinence: Ensure correct diagnosis before initiating treatment 3
• Inadequate trial of conservative therapy: Allow sufficient time (8-12 weeks) for PFMT to show benefit 3
• Overlooking mucosal atrophy: Address with vaginal estrogen in postmenopausal women 3
• Rushing to surgical options: Exhaust conservative measures first 3
• Medication contraindications: Antimuscarinic medications are contraindicated in narrow-angle glaucoma 3
• Treating asymptomatic bacteriuria: Common in older women and should not be treated with antibiotics 2

By following this structured approach to treating urinary frequency, clinicians can effectively manage symptoms and improve patients' quality of life while minimizing adverse effects.
