Final answer:
Systemic antifungal treatment for candiduria is necessary when symptoms present, in patients with a compromised immune system, or when candiduria persists after catheter removal. Thus, option 4, 'All of the above', is the correct comprehensive answer.
Step-by-step explanation:
Candiduria is the presence of Candida species in the urine, which can be a concern for certain individuals. When considering the treatment of candiduria with systemic antifungal medication, the guidelines suggest that treatment is necessary in specific circumstances:
- When there are symptoms of candiduria, such as pain, fever, or urinary urgency.
- When candiduria is detected in a patient with a compromised immune system, such as those with HIV/AIDS, cancer, or undergoing immunosuppressive therapy.
- When candiduria persists despite the removal of a urinary catheter the Candida species could potentially invade tissues and become systemic.
In essence, option 4, 'All of the above', correctly identifies the situations when systemic antifungal treatment for candiduria is warranted.
