Diphtheritic cystitis
ICD-10 A36.85 is a billable code used to indicate a diagnosis of diphtheritic cystitis.
Diphtheritic cystitis is a rare but serious condition characterized by inflammation of the bladder due to infection with the diphtheria bacillus, Corynebacterium diphtheriae. This infection can lead to necrosis of the bladder wall, resulting in severe symptoms such as dysuria, hematuria, and abdominal pain. The condition is often associated with systemic diphtheria infections, particularly in individuals with compromised immune systems or those who are unvaccinated. Diagnosis typically involves clinical evaluation, urine culture, and possibly cystoscopy to assess the extent of bladder involvement. Treatment primarily focuses on the administration of diphtheria antitoxin and antibiotics, such as penicillin or erythromycin, to eradicate the bacteria. Due to the potential for antibiotic resistance, susceptibility testing is crucial to guide effective therapy. Early intervention is essential to prevent complications such as bladder perforation or systemic spread of the infection.
Detailed history of infection, treatment response, and laboratory results.
Patients presenting with urinary symptoms and a history of diphtheria exposure.
Consideration of vaccination history and potential for co-infections.
Cystoscopy findings, imaging studies, and treatment plans.
Patients with recurrent urinary tract infections and abnormal bladder findings.
Need for thorough documentation of bladder health and any surgical interventions.
Used when urine culture is performed to identify C. diphtheriae.
Document the source of the culture and results.
Infectious disease specialists may require additional details on resistance patterns.
Common symptoms include dysuria, hematuria, abdominal pain, and fever. Patients may also present with systemic symptoms if the infection is severe.
