Supplementary Material for: Laparoscopic Treatment of Simultaneous Tumors in the Liver and Kidney

<i>Background/Aims:</i> To report our experience with laparoscopic treatment of liver tumors during right-sided transperitoneal laparoscopic nephrectomy. <i>Methods:</i> Two patients undergoing transperitoneal laparoscopic radical nephrectomy on the right side each had a concomitant tumor in the right lobe of the liver. The first patient was incidentally found to have a lesion suspicious for metastatic disease. The second had a known asymptomatic giant hemangioma of the liver. <i>Results:</i> Total operative time was 130 and 101 min. Estimated blood loss was 400 and 300 ml. There were no complications. The first patient had bilateral papillary renal cell carcinoma and concomitant fibroadipose tissue within the liver. The second patient presented with clear cell carcinoma of the right kidney and a cavernous hemangioma of the liver. <i>Conclusions:</i> When indicated, simultaneous right-sided kidney and liver tumors may be treated by a combined laparoscopic transperitoneal approach. Laparoscopic expertise is advised.
