We present a 25-year-old man with chyluria resulting from a posttraumatic, postinflammatory lymphaticopelvic fistula. This aberrant connection between the lymphatic system and the urinary tract is rarely seen in the United States and can be difficult to diagnose. In this particular case, lymphangiography and postprocedure computed tomography (CT) imaging were used to diagnose and localize a fistula involving the right renal pedicle lymphatics and right urinary collecting system. This fistula ultimately resolved after the procedure and did not require sclerotherapy or surgical intervention. Lymphangiography is now rarely performed at most centers due to advancements in alternative diagnostic imaging modalities. However, this procedure remains a useful tool for the investigation and treatment of chyluria and other chyle leaks.
