Reninoma: A Case of a Small Renal Mass Removed with Robotic-Assisted Surgery

Abstract

# Introduction Juxtaglomerular cell tumors, also termed reninomas, are rare kidney tumors that usually present at a young age with symptoms of secondary hyperaldosteronism. Reninomas are generally considered benign tumors, with surgical removal considered the treatment of choice. # Case presentation We present the case of a 32-year-old young woman with a 10-year history of hypertension who was referred to our urology department for the surgical removal of a small renal mass. The tumor was successfully removed with robotic-assisted surgery, with the pathological work-up confirming the diagnosis of reninoma. # Conclusion The case is remarkable for the long history of hypertension in this young patient in the run-up to the finding of the renal mass. We also confirm that robotic-assisted partial nephrectomy is feasible and safe for patients with suspected reninoma and due to the procedure's advantages can be considered the method of choice, if available.
