title: Spontaneous peripelvic extravasation due to squamous cell carcinoma of the ureter.
abstract: A case of spontaneous urinary peripelvic extravasation secondary to an obstructing squamous cell carcinoma of the ureter is presented. A review of the literature reveals that peripelvic extravasation caused by tumor obstruction of the ureter is rare and most of its underlying lesions are metastatic retroperitoneal adenopathy.
