In 24 patients with malignant kidney tumours percutaneous embolizations of the arteria renalis were performed in about 1 year. The material for embolization was gelatine-sponge-particles. The embolization was done pre-operatively, usually in connection with the arteriographie examination of kidney tumours (hypernephroid carcinoma). In 2 patients without operation it was done as a palliative measure. Our favourable results to improve the operability of tumours agree with reports in the literature. According to our opinion the pre-operative embolization of the arteria renalis with kidney tumours offers the possibility of a blood-sparing operation and a reduction of tumour-cell outwashings.
Though cancer of the prostate is generally regarded as a fairly benign tumour with long survival, many patients die of it. The sovereignty of hormone therapy seems questionable in the light of recent experience. A selected patient material with early stage cancer of the prostate--incidental findings at the Freyer-Hryntschak operation for bladder neck adenoma--is presented for the illustration of the prognostic aspects of this tumour. Androgen control therapy was given postoperatively to every patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
