Eosinophilic cystitis: advanced disease requiring surgical intervention

Area of Science:

• Urology
• Pathology

Background:

• Eosinophilic cystitis (EC) is a rare bladder condition of unknown etiology.
• It can present symptomatically similar to bladder neoplasms and interstitial cystitis, complicating diagnosis.

Observation:

• This report details three cases of advanced EC.
• These patients exhibited resistance to multiple treatments including antibiotics, antihistamines, and steroids.

Findings:

• Conventional therapies such as antibiotics, antihistamines, steroids, and fulguration were ineffective in managing these advanced EC cases.
• Surgical intervention, specifically cystectomy and urinary diversion, was ultimately required for all three patients.

Implications:

• The findings highlight the potential for advanced eosinophilic cystitis to be refractory to standard medical and minimally invasive treatments.
• Cystectomy and urinary diversion represent a necessary, albeit drastic, treatment option for select, treatment-resistant EC cases.
• Further research into the etiology and novel therapeutic strategies for eosinophilic cystitis is warranted.
