Resection in renal tumour patients.

: Nine cases (two of them bilateral) of renal resections for renal tumour are reviewed. The survival results of patients with bilateral renal tumours are considered particularly favourable, one of them has survived for 72, the other for 37 months. Of the patients with solitary renal tumour, one was lost 25 months postoperatively, after the development of a distant metastasis. The other patient has been free of recurrence and metastases after 31 months. The above results have proved the outdatedness of the old concept, i.e. to remove the tumorous kidney. As supported by the authors' cases, their patients have had a high survival rate after resection for renal tumour. The clear-cell tumours are well demarcated by a fibrous capsule and they can easily be resected. The granular-cell renal tumours are localized more centrally, they often infiltrate the kidney. In cases cautiously considered, the resection of the tumorous kidney can be performed under the present technical conditions by strict 6 monthly postoperative urographic, ultrasound, and angiographic examinations.
