Functional bladder capacity can reflect the bladder condition and treatment outcome in patients with interstitial cystitis/bladder pain syndrome

Key Points

• Functional bladder capacity correlates with bladder pain syndrome severity, indicating its role in assessing conditions.
• Patients showed a significant improvement in treatment outcomes, with functional bladder capacity increasing by 30%.
• Observational analysis across multiple clinics evaluated the relationship between bladder capacity and interstitial cystitis.
• Findings may enable better personalized treatment strategies; further validation in larger cohorts is needed.
