Abstract
Myiasis is caused by the larval stages of flies feeding on live or dead mammalian tissues and fluids. Human cases involving the genitourinary system are very rare and present with unusual symptoms.We report the case of a male, 25-year-old shepherd who underwent a surgical intervention on his urinary tract for renal lithiasis and was catheterized with a drain dwelling in his left kidney. A few days after the patient showed signs of dysuria, polyuria and pollakisuria. Lower urinary tract infection with ciprofloxacin susceptible E. coli was diagnosed and treated accordingly. The symptoms persisted and, a few days later, fly maggots were released repeatedly in the urine of the patient and sent for investigation. Macroscopic analysis and microscopy were performed. We detected 3-4 mm long, dorso-ventrally flattened white live fly larvae with lateral projections, typical for Fannia (Diptera: Fannidae) genus. Identification on a species level could not be performed as larva feeding facilities or specific DNA based methods were not available for us.Even if maggot urinary tract infestations are extremely rare in Europe, we should consider them in order to provide a rapid and correct diagnosis followed by an adequate treatment.
