Abstract

Urogenital myiasis is a rare parasitic infestation caused by dipteran larvae and is infrequently reported in non-endemic regions. This case report documented the first diagnosed case of Psychoda albipennis-induced urinary myiasis in a 41-year-old man from Sanandaj, Iran. The patient presented with dysuria and recurrent passage of mobile black-grayish particles in his urine over 2 months, following prolonged exposure to freshwater environments during fishing activities in Kermanshah Province. Morphological examination of the expelled larvae confirmed identification of P. albipennis using standard taxonomic keys, with emphasis on characteristic morphological structures. Laboratory analyses, including urinalysis and hematological profiling, ruled out bacterial infections, and imaging studies revealed no urinary tract abnormalities of the urinary tract. Treatment with oral ivermectin (200 µg/Kg) along with adequate hydration resulted in symptom resolution and cessation of larval excretion. Clinical symptoms subsided within 48 hours, and no larvae were observed in the urine after 1 week. This case underscored the facultative role of P. albipennis in urogenital myiasis, potentially associated with environmental exposure and compromised hygiene conditions. It highlighted the diagnostic challenges in differentiating myiasis from conventional urinary infections and emphasized the need for increased clinical awareness in regions with suboptimal sanitation. The findings supported the implementation of integrated public health strategies, including improved sanitation infrastructure and community education, to mitigate the risk of infestation. Further studies incorporating molecular diagnostic methods are recommended to enhance species-specific identification and epidemiological surveillance, particularly in resource-limited settings.
