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

Abstract

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 presentationWe 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 roboticassisted surgery, with the pathological work-up confirming the diagnosis of reninoma. ConclusionThe 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 roboticassisted 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.
