Robot assisted partial nephrectomy (Da Vinci) in an angiomyolipoma associated to Wünderlich Syndrome.

OBJECTIVE To describe a case of renal angiomyolipoma treated by robotic assisted surgery. METHOD AND RESULTS We report the case of a 26 year old females patient, in the context of third month pregnancy, who was diagnosed of spontaneous self-limited retroperitoneal hemorrhage due to renal angiomyolipoma. The patient was treated conservatively until normal delivery. At the 3rd month postpartum a robot-assisted (Da Vinci S) nephron sparing surgery (partial nephrectomy) was performed. CONCLUSION Despite being a benign tumor, there are cases in which the renal angiomyolipoma requires surgical treatment. To our knowledge, after a thorough review of the literature, this would be the first reported case of angiomyolipoma treated with conservative surgery with robotic assistance (Da Vinci S-HD).
