[Kidney cyst puncture for diagnosis and therapy]

It is reported on 38 punctures of avascular space occupying lesions of the kidney. The method is little stressing and poor of risk. It is recommended above all for older patients for the exclusion of an avascular tumour or a tumour within a cyst. The demonstration of the cyst in the double contrast may be performed following the angiography. The simultaneous therapeutic effect of the obliteration of a benign cyst be instillation of Propyliodon and Vistarin is desirable. A positive effect (complete obliteration including essential shrinking) was observed in 91%. Roentgenograms without contrast medium are not sufficient for course control. When the results of the demonstration of the hollow space, the cytology and the arteriography are unclear, operation is recommended.
