What is the initial workup and management for a patient presenting with urinary urgency?

Initial Workup and Management for Urinary Urgency

The initial workup for urinary urgency should include a comprehensive assessment of bladder symptoms, physical examination, and urinalysis to rule out infection and hematuria, followed by first-line treatment with behavioral therapies such as bladder training for urgency urinary incontinence (UI). 1

Initial Evaluation

History and Symptom Assessment

• Obtain a detailed history with comprehensive assessment of bladder symptoms, including time of onset, specific symptoms, and frequency 1
• Determine if symptoms are consistent with urgency UI (involuntary loss of urine associated with sudden compelling urge to void), stress UI (related to urethral sphincter failure with intra-abdominal pressure), or mixed UI (combination of both) 1
• Assess impact on quality of life, as effects range from slightly bothersome to debilitating 1
• Identify risk factors including pregnancy, pelvic floor trauma, menopause, hysterectomy, obesity, urinary tract infection, cognitive impairment, chronic cough, and constipation 1

Physical Examination

• Conduct a physical examination to evaluate for underlying conditions 1
• Assess for pelvic organ prolapse which may require specialist referral 2

Laboratory Testing

• Perform dipstick or microscopic urinalysis to rule out infection and hematuria 1
• Obtain urine culture if urinalysis suggests infection 1

Management Algorithm

Step 1: Behavioral Interventions (First-Line)

For patients with urgency UI:

• Bladder training is strongly recommended as first-line treatment (strong recommendation, moderate-quality evidence) 1
• Bladder training involves behavioral therapy that includes extending time between voiding 1

For patients with stress UI:

• Pelvic floor muscle training (PFMT) is strongly recommended (strong recommendation, high-quality evidence) 1

For patients with mixed UI:

• PFMT combined with bladder training is strongly recommended (strong recommendation, moderate-quality evidence) 1

Step 2: Lifestyle Modifications

• Weight loss and exercise for obese women with UI (strong recommendation, moderate-quality evidence) 1
• Management of fluid intake: adequate hydration without excessive fluids 2, 3
• Avoidance of bladder irritants in diet (e.g., caffeine, alcohol) 1, 3
• Timed or prophylactic voiding 4, 3
• Treatment of constipation 1, 3
• Smoking cessation 3

Step 3: Pharmacologic Treatment (If Behavioral Therapy Unsuccessful)

For urgency UI:

• Pharmacologic treatment is recommended if bladder training was unsuccessful (strong recommendation, high-quality evidence) 1
• Choice of medication should be based on tolerability, adverse effect profile, ease of use, and cost 1
• Options include:
  • Antimuscarinic agents: oxybutynin, tolterodine, darifenacin, solifenacin, fesoterodine, and trospium 1
  • β-3 adrenergic agonists: mirabegron for treatment of OAB with symptoms of urge urinary incontinence, urgency, and urinary frequency 5

For stress UI:

• Systemic pharmacologic therapy is NOT recommended (strong recommendation, low-quality evidence) 1
• Vaginal estrogen formulations may improve continence and stress UI 1

Special Considerations

Medication Selection

• Tolterodine causes fewer adverse effects than oxybutynin with similar efficacy 1
• Solifenacin has the lowest risk for discontinuation due to adverse effects, while oxybutynin has the highest risk 1
• Common adverse effects include dry mouth, constipation, and blurred vision for antimuscarinics; nasopharyngitis and gastrointestinal disorders for mirabegron 1, 5
• Poor adherence to pharmacologic treatments is common due to adverse effects 1

When to Refer to a Specialist

• For patients with refractory symptoms despite behavioral therapy and oral medications 6, 2
• Advanced therapies available through specialists include:
  • Sacral neuromodulation
  • Percutaneous tibial nerve stimulation
  • Intradetrusor injection of onabotulinumtoxinA 6, 2

Common Pitfalls to Avoid

• Failure to identify medications that may cause or worsen UI 1
• Overlooking conditions that may cause UI such as urinary tract infections, metabolic disorders, excess fluid intake, and impaired mental conditions 1
• Underdiagnosis is common - at least half of women with UI do not report the issue to their physicians 1
• Discontinuing treatment too early, as most cases of OAB are not cured but rather symptoms are reduced 4

By following this evidence-based approach to the workup and management of urinary urgency, clinicians can effectively address this common condition and significantly improve patients' quality of life.
