Background:
There are many causes of acute renal failure, with cases often being classified as pre-renal, intrarenal or post-renal based on the etiology. A post-obstructive etiology is responsible in a minority of patients. Infectious causes of post-obstructive azotemia are even more rare, but as this case illustrates, should be considered as part of the differential.
Case Report:
This case report describes a patient who developed acute renal failure (ARF) while hospitalized. Examination showed a candidal plug at his urethral meatus. Bladder washings removed a significant amount of purulent material. Treatment for C. albicans with fluconazole resolved his urinary retention and his bilateral hydronephrosis. His acute renal failure was due to an infectious, post-obstructive pyocystitis and formation of a candidal plug in his urethral meatus.
Conclusions:
Removal of the candidal plug and treatment of his infection with fluconazole resulted in return to baseline renal function. While not common, an infectious cause of post-renal azotemia should be considered in the appropriate clinical situation.
Insights
A rare fungal infection caused a urinary blockage, leading to acute renal failure (ARF). Prompt treatment with fluconazole resolved the obstruction and restored kidney function, highlighting the importance of considering infectious causes of post-renal azotemia.
Area of Science:
- Nephrology
- Infectious Diseases
- Urology
Background:
- Acute renal failure (ARF) can stem from various causes, categorized as pre-renal, intrarenal, or post-renal.
- Post-obstructive etiologies account for a small fraction of ARF cases.
- Infectious causes of post-obstructive azotemia are exceptionally rare but warrant consideration.
Observation:
- A hospitalized patient presented with acute renal failure.
- Examination revealed a candidal plug obstructing the urethral meatus.
- Significant purulent material was found in bladder washings.
Findings:
- The patient's acute renal failure was attributed to infectious post-obstructive pyocystitis and a urethral candidal plug.
- Treatment with fluconazole successfully addressed the Candida albicans infection.
- Urinary retention and bilateral hydronephrosis were resolved.
Implications:
- Resolution of the candidal plug and antifungal treatment led to the return of baseline renal function.
- This case underscores the necessity of considering infectious etiologies in post-renal azotemia.
- Early diagnosis and targeted treatment are crucial for managing rare causes of ARF.
