title: Fluoroscopically guided skinny-needle aspirative biopsy in normal and suspected lymph nodes in urologic cancer.
abstract: The authors present their experience with transperitoneal thin-needle biopsy of the retroperitoneal lymph nodes. This method is a means of improving lymphographic diagnosis in suspected lymph node metastases, the small contrast defects serving as a sign. The high rate of false-negative results makes its use unadvisable in patients with negative lymphography where the sample cannot be aimed at but is multiple and randomized.
