Description of LND templates in the included studies

Study	Use of LND template
Azawi et al. [9]	Left side: left renal hilar to longitudinal midline of aorta Right side: right renal hilar to longitudinal midline of aorta Caudal border: level of the aortic bifurcation
Kanno et al. [14]	Left side: renal hilar and para-aortic LN Right side: renal hilar, paracaval, retrocaval, and intra-aortocaval LN Cranial border: 1–2 cm higher than the renal hilum Caudal border: level of the aortic bifurcation
Kondo et al., [15] Kondo et al. [16] Kondo et al. [17]a	Right: right renal hilar, paracaval, retrocaval, inter-aortocaval Left: left renal caval, para-aorta, aortic bifurcation
Kondo et al. [18]	Renal pelvis: Left: left renal hilar, para-aorta down to the level of IMA Right: right renal hilar, para-caval, Interaortocaval down to the level of IMA Upper 2/3 ureter: Left: left renal hilar, para-aorta down to the level of aortic bifurcation Right: right renal hilar, para-caval, Interaortocaval down to the level of aortic bifurcation Lower 1/3 ureter: Ipsilateral common iliac, external iliac, internal iliac, obturator
Miyake et al. [19]	Renal pelvis or upper ureter: from para-aorta to vena cava Cranial border: renal hilum Caudal border: IMA Mid-ureter: from para-aorta to vena cava Cranial border: renal hilum Caudal border: bifurcation of the common iliac artery Lower ureter: Ipsilateral pelvic nodes on the ipsilateral side (Greater extent carried out when multiple tumours were located in different areas of the ureter)

IMA: inferior mesenteric artery.
