[Indication and diagnostic value of roentgen-guided fine-needle puncture of space-occupying renal lesions (author's transl)].

Roentgen-guided fine needle puncture of space-occupying renal lesions as an important additive radiologic procedure is able to solve differential diagnostic problems of liquid or solid renal lesions in a quick, accurate and safey way. It rules out a solid neoplasm, provides the surgeon with a maximum of preoperative information and helps to avoid operations on aged and other poor-risk patients. After description of the puncture technique we report the result of 217 fine needle punctures of the kidney over 13 years.
