[Therapy planning and prognosis evaluation in malignant kidney neoplasms. A lymphographic study of 50 malignant kidney neoplasms].

Of fifty patients with malignant renal tumors who underwent lymphographic examination, 15 (30%) had lymph node metastases. Two years from the beginning of therapy, 13 of these patients were deceased in spite of surgical and radiological treatment. The enhancement of the five-year survival rate following radiation therapy for malignant renal tumors is quoted between 7 and 26%. This success is probably due to the destruction of micrometastases, not being representable lymphographically. Radiation therapy of malignant renal tumors, therefore, can only be effective including the para-aortic lymphatic chains.

[Conservative elective surgery in kidney neoplasms].

After the good results of "necessary" conservative surgery in the treatment of kidney neoplasms (bilateral neoplasms, congenital, acquired or functional solitary kidney), conservative surgery itself has been employed as elective treatment in selected cases presenting without the overmentioned problems. The authors report two cases of elective conservative surgery in kidney neoplasm with good results after 18 and 24 months.

Kidney neoplasms.

The author reviews the diagnosis and treatment of carcinoma of the kidney. Surgery remains the most effective therapy. The management of metastatic disease is discussed.

[Preoperative embolization of the renal artery in kidney neoplasms].

In 15 patients with extensive malignant renal tumours before operation the artery of the kidney concerned was closed by foam substance particles (ivalon) after percutaneous selective catheterisation. The occurring ischaemic pain was controllable by medicaments and eased off after hours. In most cases the nephrectomy followed on the same day, but it can be performed also on the following day. The operation was principally performed from the transverse flank cut in practically bloodless kidney. Compared with the major interventions (transthoraco-abdominal or transabdominal) of the tumour nephrectomy the procedure described in this paper as a more careful one which at the same time meets the principles of modern surgery of cancer and which can also suggested to patients suffering from a severe disease.
