We report a case of an obstructing fungus ball of the urinary tract. T
ypical predisposing factors were present, i.e. bladder catheter, vesic
o-ureteral reflux, urinary infection, parenteral nutrition, prolonged
antibiotherapy, hyperglycemia. Candida albicans septicemia was noted.
Diagnosis was made by percutaneous nephrostomy under echographic contr
ol allowing urinary sampling (C. albicans) and anterograde pyelography
showing an ureteral stenosis. Urinary drainage and local and general
administration of amphotericin lead to a complete resolution of the fu
ngus ball and the systemic candidiasis.
