Renal Mucormycosis in a Healthy Boy for Ten Years: A Novel Case Report

: Mucormycosis is rare in urinary tract infections. Renal mucormycosis is considered in immunocompromised patients and is associated with a high mortality rate. Herein, we presented the first case of a non-invasive fungus ball caused by a Rhizopus species confined to the unilateral kidney in a healthy boy for approximately ten years. The etiology was identified using next-generation deoxyribonucleic acid (DNA) sequencing. The patient recovered completely after nephrectomy without bladder irrigation. Therefore, clinicians must have a high index of suspicion for fungal infections in refractory urinary tract infections. Next-generation DNA sequencing technology can be used for an accurate diagnosis.
