[A modified maneuver in radical nephrectomy]

From 1975 to 1988 nephrectomy was carried out in 59 cases with renal cell cancers over 6 cm in diameter. A comparison was made between two manoeuvres of conventional group (Ligating renal arteries and veins simultaneously) and modified group (First ligating renal arteries). In the conventional group (35 cases) 22 cases (68.85%) needed a transfusion over 600 ml and in modified group (24 cases) only 5 cases (20.8%) needed over 600 ml. Amount of blood required was significantly larger in the former. In conventional group 3 cases occurred slipping of ligature (1 case died) and in modified group no this accident occurred.
