Human dirofilariasis of the bladder

We report the first case of dirofilariasis of the human bladder. This organism is endemic in the southern and southeastern United States, and is responsible for the common dog heartworm disease. Since man is an unnatural host for this parasite this disease in humans still is uncommon, although it has been reported with increasing frequency in the last 3 decades. Transurethral resection was adequate for complete control in this patient and followup has revealed no evidence of recurrence.
