Renal cyst puncture as an important, additive radiologic technique is able to solve differential diagnostic problems of avascular, space-occupying renal lesions in a quick, accurate, and safe way. Renal cyst puncture rules out a solid neoplasm and provides the surgeon with a maximum of preoperative information. Through its use unnecessary operations on aged and poor-risk patients can be avoided. The method is described, and the results of 185 finegauge needle punctures of the kidney obtained from 2329 renal angiographies over 11 years, are reported.
