Robot-Assisted Laparoscopic Renal Schwannoma Excision

Background: To report the first case of a renal schwannoma excised with robot-assisted laparoscopy. Case Presentation: A 43-year-old Caucasian female patient with vague abdominal symptoms was noted to have incidental right renal mass. Physical examination and laboratory tests were within normal limits. CT revealed a 4.6 cm heterogeneous enhancing right renal mass arising near the hilum. RENAL nephrometry score was 11a. She was treated by right robot-assisted laparoscopic nephrectomy. She recovered well without complications. Pathology analysis revealed a benign renal schwannoma. Conclusion: Renal schwannoma is a rare kidney tumor. We report the first known case of this tumor excised by robot-assisted laparoscopic nephrectomy.
