Critical examination of the results of surgical treatment and new surgical techniques have produced changes in the operative treatment of hypernephroid kidney cancer and nephroblastoma. The limits to operative treatment are, first, the local extension and infiltration of the tumor and, second, the grade and degree of metastases. Surgical removal of the hypernephroma seems to have a positive effect on metastasis regression only in the case of bone metastases. Nephrectomy is indicated only in cases with solitary metastases which can be removed at a second operation. The possibility of arterial embolization in renal hemorrhage in inoperable patients is demonstrated. Current aspects of the operative treatment of nephroblastoma are discussed.
Renal biopsies with a new "lumboscopic" (half-open) technique were performed in 109 patients. Access to the kidney was gained by a small flank incision and biopsies from the renal cortex were taken under vision through the lumboscope. The biopsies were successful in all cases. The advantages of the new technique are convincing and lumboscopy suited to replace the regular open biopsy procedure.
Critical examination of the results in surgical treatment and new surgical techniques have lead to some changes in operative therapy of hypernephroid kidney cancer. Indications for surgical treatment and different operative techniques are described in dependence of grade of metastases. The possibility of arterial embolization in renal hemorrhage in inoperable patients is discussed.
In a study of the kidney biopsies from 192 patients, the results, intra- and postoperative complications, and specific advantages and disadvantages of the conventional open biopsy are compared with those of the half-open, lumboscopic technique. Most of the advantages clearly confirm the superiority of the lumboscopic technique, which, thus has the necessary prerequisites for replacing the regular surgical biopsy.
