Laparoscopic radical nephrectomy for a right renal tumor with renal vein tumor thrombus in a patient with situs inversus totalis

Abstract

Situs inversus totalis (SIT) is a rare congenital anomaly characterized by complete inversion of the thoracic and abdominal organs. Many intra‐abdominal and vessel anomalies have been reported in association with SIT. However, there have been no reports on the use of laparoscopic radical nephrectomy with thrombectomy for renal vein thrombus, which is considered as a safe and feasible procedure, in patients with SIT. We herein present the case of an 80‐year‐old man with SIT who was preoperatively diagnosed with a right renal tumor and renal vein tumor thrombus. The patient underwent laparoscopic right nephrectomy and tumor thrombectomy with no intraoperative complications. To ensure a safe procedure, the anatomy and vessels were carefully evaluated preoperatively using 3‐D multiplanar reconstructed CT imaging. Assessing anatomical structures leads to safer laparoscopic radical nephrectomy for renal cell carcinoma with venous tumor thrombus in patients with SIT.
