Overview
Emphysematous cystitis is a rare, severe infection of the bladder characterized by gas production within the bladder wall, often caused by gas-forming organisms such as Clostridium perfringens and Candida species. It can lead to significant morbidity and mortality, particularly in immunocompromised patients 23.Diagnosis
Clinical presentation includes fever, abdominal pain, and hematuria 3.
Imaging studies, particularly CT urography, are crucial for visualizing gas within the bladder wall 2.
Urinalysis may show pyuria and hematuria 3.
Culture of urine and possibly bladder aspirate is essential for identifying causative organisms 3.Management
Antibiotics: Target specific pathogens identified; broad-spectrum initially if causative agents are unknown 3.
Urinary drainage: Removal or replacement of indwelling catheters and ensuring proper urinary drainage 3.
Supportive care: Management of underlying conditions and general medical support 3.
Surgical intervention: Considered only if there is evidence of bladder fistula or other complications requiring debridement 3.Special Populations
Immunocompromised patients: Higher risk due to compromised immune function; careful monitoring and prompt intervention are critical 3.
Patients with indwelling catheters: Increased risk due to potential for infection; catheter management is essential 3.Key Recommendations
Consider emphysematous cystitis in the differential diagnosis for patients with hematologic malignancies presenting with fever, abdominal pain, and hematuria (Evidence: Moderate 3).
Initiate broad-spectrum antibiotics pending culture results and tailor therapy based on identified pathogens (Evidence: Moderate 3).
Ensure prompt removal or replacement of indwelling catheters and establish adequate urinary drainage (Evidence: Moderate 3).References
