— The DNA histograms of 21 conservatively resected renal tumours were studied using DNA flow cytometry. Five patients had an imperative and sixteen an elective indication for conservative resection of the renal tumour. On the basis of DNA histograms twelve aneuploid tumours were pointed out. A mean follow-up of 34.2 months was considered to see whether the ploidy would provide criteria with a prognostic significance, to be useful as an additional parameter. None of the twenty-one patients had local recurrence or distant metastasis: in our series the DNA analysis had no influence on the prognosis of this group of patients. The tumour size seems to be the only selective parameter for choosing renal-conserving surgery.
