A man with encrusted cystitis caused by Corynebacterium urealyticum experienced hydronephrosis. Treatment with quinolones and urine acidification successfully resolved the calcifications and improved kidney function.
Area of Science:
- Urology
- Infectious Diseases
- Nephrology
Background:
- Encrusted cystitis is a severe bladder infection often caused by urease-producing bacteria.
- Corynebacterium urealyticum is a challenging pathogen associated with encrusted cystitis and potential upper urinary tract damage.
Observation:
- A 61-year-old male presented with encrusted cystitis and bilateral hydronephrosis.
- These complications arose four months post-adenomectomy, complicated by a vesicocutaneous fistula.
Findings:
- Medical management utilizing quinolones was initiated.
- Oral acidification of the urine was also administered as part of the treatment regimen.
Implications:
- The combined therapy led to the regression of encrusted calcifications.
- Successful resolution of bilateral hydronephrosis was achieved, highlighting effective treatment strategies.
