title: Primary leiomyosarcoma of ureter.
abstract: The tenth case of primary leiomyosarcoma of the ureter is reported, and previous cases are summarized. It is the first example studied by percutaneous pyelography and ultrasonography. The former was more informative than retrograde ureterography. The ultrasonic study suggested a cystic lesion rather than the solid tumor encountered. Nephroureterectomy, selective para-aortic node dissection, and radiotherapy were used, but distant metastasis and death ensured fifteen months later.
