[Eosinophilic cystitis: review and two case reports]

Area of Science:

• Urology
• Pathology

Background:

• Eosinophilic cystitis is a rare bladder condition characterized by eosinophilic infiltration, fibrosis, and muscle necrosis.
• Potential triggers include allergies, bladder injury, drugs, and infections, with an apparent immunological origin.
• The condition affects all ages but predominantly adults, presenting with urinary frequency, hematuria, and suprapubic pain.

Observation:

• Diagnostic imaging and laboratory tests are non-specific for eosinophilic cystitis.
• Cystoscopy may mimic other bladder pathologies, underscoring the need for histological confirmation.
• Histological analysis is the definitive method for diagnosing eosinophilic cystitis.

Findings:

• Two adult male cases of eosinophilic cystitis are presented, detailing their specific symptoms, diagnostic studies, and management approaches.
• The reported cases illustrate the clinical presentation and diagnostic challenges associated with this uncommon disease.

Implications:

• Accurate diagnosis through histology is crucial for appropriate management of eosinophilic cystitis.
• Treatment strategies include observation, pharmacotherapy (antihistamines, anti-inflammatories, corticosteroids), and surgical intervention for refractory cases.
• Further research into the immunological triggers of eosinophilic cystitis may lead to more targeted therapies.
