Abstract

Urogenital myiasis is a rare parasitic infestation caused by larvae Psychoda albipennis. The settlement, feeding, and activity of larvae in urogenital tracts lead to disorders of the urinary and reproductive systems. This study presents a 36-year-old man with the main complaint of dysuria, hematuria, urethral discharge, and abdominal flank pain. He observed some black-grayish-colored mobile particles in his urine three times over eight months period. He was referred to the urology outpatient clinic and received anti-cystitis and/or urethritis treatment. But his symptoms did not improve and observed some larvae in his urine. After investigations of his urine under the light microscope, some alive, stirring, and hairy larvae (approximately 1 cm in length) were identified as the fourth-stage larvae of the moth fly, Psychoda Albipennis based on morphological characteristics. Human urogenital myiasis caused by Psychoda Albipennis is an infrequent infection disease in Iran. It seems that urinating in poor hygiene environments, sleeping without a blanket in traveling to the countryside on the banks of the Dez River, in the north of Khuzestan province, and urination in unsanitary toilets were the main risk factors of urogenital myiasis inrecent case. The use of appropriate antiseptic medication, and drinking plenty of water improved patient complaints following the two-week treatment period. The urogenital myiasis is an uncommon occurrence and comprises only 0.7% of all cases of human myiasis based on a few publication reports in Iran and the world. It`s the first report of urogenital myiasis caused by P. albipennis from Khuzestan province, South Western Iran.
