title: Wilms' tumor: a new cause for urinary extravasation.
abstract: We report a case of Wilms' tumor associated with urinary extravasation due to tumor invasion through the renal pelvis and anterior renal capsule. Extravasation of urine exposed to tumor may lead to upstaging of the tumor and the requirement for more intensive therapy.
