title: Fine needle biopsy of metastases at retrograde pyelography, directed by fluoroscopy. Report of a case with malignant teratoma of the testis.
abstract: Percutaneous fine needle aspiration biopsy was performed at retrograde pyelography in order to differentiate between metastatic and scarry involvement of a strictured ureter in a patient earlier operated upon because of malignant teratoma. The method is recommended in patients with malignant diseases where the differential diagnosis is impossible to establish at retrograde pyelography or urography.
