Urinary tract fungal ball in a single kidney after total nephroureterocystectomy

Abstract

Introduction Fungal balls in the urinary tract are rare but dangerous complications of candiduria. Here, we report a case of a urinary tract fungal ball in a single kidney after total nephroureterocystectomy. Case presentation The patient was an 80‐year‐old male. He had a history of pyelonephritis, and his ureteral stent was regularly replaced. He was admitted to the hospital with a chief complaint of urinary tract obstruction, and a 50‐mm‐sized mass was found within the renal pelvis. Because the ureteral stent frequently became obstructed, the mass was removed percutaneously. Candida albicans was detected on the tissue culture results, and the mass was diagnosed as a fungal ball. Conclusion Appropriate urinary drainage methods for fungal balls vary among patients, and it is important to select an appropriate method based on the accumulated number of cases.
