Abstract:
Candida albicans is a fungus that can cause opportunistic urinary tract infections in immunocompromised patients. Disseminated fungaemia secondary to Candida albicans is associated with considerable mortality and therefore merits aggressive treatment. Diagnostic investigations for urosepsis and disseminated fungaemaia secondary to Candida albicans include positive urine and blood cultures. Herein, we describe an extremely unusual case of disseminated fungaemia associated with an obstructive fungus-ball in the distal ureter of an immunosuppressed patient. We also describe a novel application of an established endourological technique for managing this clinical scenario and discuss appropriate perioperative management strategies.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
