Abstract and Introduction

We present a case believed to be the first reported North American presentation of Ascaris lumbricoides within the urogenital tract. A young man came to the emergency department because of painless hematuria and having observed a 6-inch worm exit his urethra while urinating. The most common site for A lumbricoides infection is the gastrointestinal tract, specifically the area of the hepatopancreatic ducts. Worldwide, A lumbricoides infections are ubiquitous, but infections outside the alimentary tract are extremely rare.

Ascaris lumbricoides infection is usually limited to the respiratory and gastrointestinal tracts. Signs and symptoms are coincident with the life cycle of the parasite as it migrates from the lung to the intestine. In the following case, the patient excreted a live Ascaris worm from the urethra.
