Clinical guidelines for interstitial cystitis and hypersensitive bladder syndrome

Area of Science:

• Urology
• Clinical Medicine
• Gastroenterology

Background:

• Interstitial cystitis (IC) and hypersensitive bladder syndrome (HBS) are debilitating bladder conditions.
• Current diagnostic criteria and treatment options require refinement.
• East Asian urologists have revised existing guidelines.

Purpose of the Study:

• To present a revised clinical guideline and algorithm for IC and HBS.
• To standardize diagnostic criteria for IC and HBS.
• To address the multifactorial etiology and therapeutic challenges of IC.

Main Methods:

• Development of a revised clinical guideline based on the Japanese guideline for IC.
• Definition of IC through three key requirements: symptom complex, bladder pathology, and exclusion of other diseases.
• Definition of HBS as bladder hypersensitivity, often with urinary frequency and/or pain, when IC is suspected but not confirmed.

Main Results:

• The guideline provides clear diagnostic criteria for IC and HBS.
• Cystoscopy and hydrodistension are identified as crucial for definitive IC diagnosis.
• Most available therapies for IC lack high-level evidence, with few recommended treatments.

Conclusions:

• The guideline aims to improve the diagnosis and management of IC and HBS.
• Standardizing inclusion and efficacy criteria for clinical trials is essential for advancing research.
• IC/HBS is more prevalent than previously recognized, necessitating further investigation.
