Eosinophilic ureteritis presenting as bilateral upper ureteric strictures

Abstract

During evaluation for loin pain a 54‐year‐old man was found to have bilateral upper ureteric strictures with hydroureteronephrosis on imaging. Renal function tests were normal. There was no peripheral eosinophilia but an excision biopsy of the stricture revealed eosinophilic ureteritis. As the patient had a previous history of cellulitis with epididymitis and came from an endemic area, filariasis should be considered as a possible triggering etiology.
