Successful robot-assisted partial nephrectomy for giant renal hilum angiomyolipoma through the retroperitoneal approach: A case report

Abstract

BACKGROUND: Giant renal angiomyolipomas (AMLs) may lead to complications including flank pain, hematuria, hypertension, retroperitoneal hemorrhage and even death. Giant AMLs which grow around renal hilar vessels and the ureter are rare. Most previous reports on the treatment of giant renal AMLs have focused on open surgery or a transperitoneal approach, with few studies on the retroperitoneal approach for large AMLs. We here report a case of giant renal hilum AML successfully treated with robot-assisted laparoscopic nephron sparing surgery the retroperitoneal approach, with a one-year follow-up. CASE SUMMARY: the retroperitoneal approach was performed. The patient had no serious postoperative complications and was discharged soon after the operation. At the one-year follow-up, the patient's right kidney had recovered well. CONCLUSION: the retroperitoneal approach, LPN for giant central renal AMLs can be completed using a well-designed procedure with the assistance of a robotic system.
