Laparoscopic Thrombectomy of Renal Angiomyolipoma Level III

Abstract

PURPOSE: Renal angiomyolipoma (AML) is a benign tumor, corresponding to approximately 3% of solid renal tumors, which has in its composition endothelial cells, myocytes and adipocytes. One of the rare complications of this type of tumor is linfonodal involvement and tumor venous dissemination forming thrombus in the renal vein and inferior vena cava and may even reach the right atrium. Surgical treatment of this type of tumor is performed mainly by open surgery, but this video shows the laparoscopic approach for level III of angiomyolipoma, showing that this approach is feasible and reproducible by any trained and experienced surgeon. MATERIALS AND METHODS: Woman of 65 years with back pain, ultrasound examination showed a tumor in the right kidney, and follow-up computed tomography revealed aspects of angiomyolipoma. We performed radical nephrectomy with thrombectomy by laparoscopy. RESULTS: The patient recovered well, enjoying all the benefits of laparoscopic surgery. There were no complications during surgery. CONCLUSIONS: The surgical approach of laparoscopic renal angiomyolipoma is a perfectly feasible, bringing numerous benefits to the patient, and can establish itself as a breakthrough in treating this type of tumor
