INTRODUCTION: To investigate the feasibility and efficiency of super-selective artery embolization (SAE) before laparoscopic partial nephrectomy (LPN) in treating renal angiomyolipoma (RAML). MATERIALS AND METHODS: A retrospective analysis was conducted on 36 consecutive patients who underwent SAE before LPN (group A, n = 16) or LPN directly (group B, n = 20) from June 2010 to March 2016. Intraoperative blood loss, blood transfusion, operation time, warm ischemia time (WIT), and prognosis were compared between groups. RESULTS: SAE before LPN decreased operating time, intraoperative blood loss and WIT (p < 0.05), and improved postoperative renal function (p < 0.001). Complications in group B included intraoperative blood loss of 4 patients and postoperative hematuria of 2 patients who recovered a few days later. No complications were observed in group A. In the follow-up of 3 months, a patient in group B formatted retroperitoneal hematoma without any symptoms and received expectant treatment. CONCLUSIONS: The application of SAE before LPN can decrease the difficulty of the surgery, the complications, and the risk of rebleeding and RAMLs recurrence.
