—Smith1 stated that either the lumbar or the transperitoneal approach may be used for removal of a tumor of the kidney. In a series of 50 cases of renal and ureteral neoplasms, the kidney was removed transperitoneally in 22 and by the lumbar route in 22. Indications for the selection of the lumbar route are: (1) uncertain diagnosis; (2) small size of the mass; and (3) probability that the growth is pelvic rather than cortical. The transperitoneal route is chosen for removal of large cortical tumors. It allows examination of the abdomen for metastatic growths before the tumor is disturbed.When the intestines are walled off from the upper part of the abdomen on the affected side, the tumor will be seen beneath the posterior portion of the peritoneum. It may be exposed through an incision made in the overlying peritoneum or in the parietal peritoneum 1
