Interstitial cystitis: early diagnosis, pathology, and treatment

Area of Science:

• Urology
• Pathology

Background:

• Interstitial cystitis (IC) presents with persistent lower urinary tract irritative symptoms, sterile urine, and negative cytology.
• Differentiating IC from urethral syndrome requires cystoscopy under anesthesia.

Purpose of the Study:

• To identify diagnostic hallmarks of interstitial cystitis.
• To characterize histological findings across different stages of IC.
• To evaluate treatment efficacy for IC.

Main Methods:

• Retrospective review of 52 patients diagnosed with interstitial cystitis.
• Cystoscopy under anesthesia to identify bladder abnormalities.
• Histopathological examination of bladder tissue.
• Evaluation of treatment response to bladder instillations.

Main Results:

• Multiple glomerulations (petechia-like hemorrhages) during bladder distention are a hallmark of IC.
• Reduced bladder capacity and Hunner's ulcer represent a classic stage of IC.
• Characteristic histology includes submucosal edema and vasodilation; eosinophils and mast cells are variable.
• Immunofluorescent studies and serological tests (e.g., FANA) were not helpful for diagnosis.
• Bladder instillations with oxychlorosene sodium (Clorpactin WCS-90) provided significant relief, especially for classic IC.

Conclusions:

• Glomerulations observed during cystoscopy are crucial for diagnosing interstitial cystitis.
• Submucosal edema and vasodilation are consistent histological findings in all stages of IC.
• Oxychlorosene sodium bladder instillations offer an effective treatment option for interstitial cystitis patients.
