Laparoscopic radical nephrectomy in ACDK-associated renal cell carcinoma accompanied by duplicated IVC: a case report

A 59-year-old male patent who had undergone chronic dialysis for 13 years presented with gross hematuria. Radiological examinations showed a cystic renal tumor in the left kidney, multiple renal cysts due to acquired cystic disease of the kidney (ACDK), and a duplicated inferior vena cava (IVC). Although we suspected that the branches of the left IVC might be anormalous with regard to number and location, we could not obtain information about the left renal vein by 3-dimensional computed tomography because of the decreased blood flow in the end-stage kidney. Laparoscopic radical nephrectomy was performed using a transperitoneal approach. We first identified the left IVC and then exposed its surface widely so that we could identify the veins draining into it. We identified and divided two renal veins and also identified an adrenal vein and a gonadal vein draining directly into the left IVC. The enlarged kidney with multiple renal cysts was removed in a purely laparoscopic procedure.
