Acute renal failure caused by fungal bezoar: a late complication of Candida sepsis associated with central catheterization.

The authors report a case of acute renal failure caused by fungal bezoar in the renal pelvis. The patient was successfully treated with bilateral percutaneous nephrostomy drainage. He had been admitted because of necrotizing enterocolitis, at the age of 26 days. Eventually, his bowel was reduced to 40 cm of small intestine, including 5 cm of terminal ileum. Candida sepsis developed during central total parenteral nutrition, at the age of 76 days. Five weeks after the diagnosis of systemic candidiasis, sudden anuria developed, and ultrasonography showed echogenic material in both renal pelvises. Bilateral percutaneous nephrostomy catheters were placed in the renal pelvises, and local irrigation with amphotericin B was performed for 3 weeks. The renal function of the baby was completely recovered, without systemic antifungal treatment.
