Fig. 2 —Genitofemoral nerve derives from first and second lumbar nerve carrying sensory and motor nerve fibers. Nerve (black line) passes through major psoas muscle (light red band) to emerge on its anterior surface and runs laterally downward to divide into genital and femoral branches. Genital branch passes through inguinal canal and supplies cremaster muscle and small area of overlying skin. Femoral branch supplies skin over femoral triangle. Renal parenchyma is shown in dark red. In described technique, applicator is used as lever to displace kidney from psoas muscle using site of skin entry (black X) as center of rotation. After torquing handle in medial direction, kidney moves laterally, enlarging distance from muscle.
