Is triamcinolone injection into the bladder a recommended treatment option?

Triamcinolone Injection for Bladder Conditions

Triamcinolone injection into the bladder is a recommended treatment option specifically for patients with interstitial cystitis/bladder pain syndrome (IC/BPS) who have Hunner lesions. 1 This targeted approach is supported by current guidelines and clinical evidence.

Indications for Triamcinolone Bladder Injection

Primary Indication: Hunner Lesions in IC/BPS

• According to the American Urological Association (AUA) 2022 guidelines, if Hunner lesions are present in patients with IC/BPS, fulguration with electrocautery and/or injection of triamcinolone should be performed (Grade C evidence strength) 1
• This treatment is particularly effective for:
  • Reducing urinary frequency
  • Decreasing urgency
  • Alleviating bladder pain
  • Improving quality of life

Patient Selection

Triamcinolone injection is most beneficial for:

• Patients with confirmed Hunner lesions on cystoscopy
• Patients with advanced age and more severe IC/BPS symptoms 2
• Patients with higher pain scores and symptom severity 2

Administration Protocol

1. Diagnostic confirmation: Cystoscopy to identify and confirm Hunner lesions
2. Injection technique:
   • Direct submucosal injection into the center and periphery of Hunner lesions
   • Typical dosage: 40 mg/ml triamcinolone acetonide in 0.5 ml aliquots 3
   • Total volume typically around 10 ml (administered in multiple small injections)
   • Performed under anesthesia using an endoscopic needle

Efficacy and Outcomes

• Symptom improvement: 70-85% of patients experience significant improvement in symptoms 3, 4
• Pain reduction: Studies show significant reduction in pain scores from baseline (VAS scores decreasing from 8 to 2.5) 4
• Duration of effect: Treatment benefits typically last 4-8 months before retreatment may be necessary 4
• Quality of life: Significant improvements in validated questionnaire scores:
  • International Prostate Symptom Score (IPSS)
  • Pelvic Pain and Urgency/Frequency (PUF) symptom scale

Important Limitations and Considerations

1. Retreatment necessity:

   • Approximately 70% of patients followed for ≥8 months require at least one retreatment 4
   • Benefits tend to diminish over time, requiring periodic reinjection

2. Contraindications:

   • Active urinary tract infection
   • Bladder malignancy
   • Patients with uncontrolled diabetes, severe hypertension, or active infections

3. Alternative approaches:

   • For non-Hunner lesion IC/BPS, triamcinolone bladder instillation (as opposed to injection) has not shown superior efficacy compared to standard instillation solutions 5
   • For diffuse bladder inflammation without discrete lesions, other treatment approaches should be considered

Clinical Pearls

• Always perform cystoscopy to confirm the presence of Hunner lesions before considering triamcinolone injection
• The treatment appears to constitute one of the few IC/BPS therapies that results in improvement measured in months with only a single procedure 1
• Counsel patients that periodic retreatment is likely to be necessary as response decreases over time
• This treatment should be performed by clinicians with experience in cystoscopic procedures and familiarity with IC/BPS management

While triamcinolone injection is not a cure for IC/BPS, it represents an important treatment option for the subset of patients with Hunner lesions, offering significant symptom relief and improved quality of life when other treatments have failed.
