Core Tip

Core Tip: Villous adenoma is a rare tumor in the urinary system. We reported a patient who was admitted to the hospital due to right kidney stones with right hydronephrosis. Biopsy indicated a villous adenoma with high-grade glandular intraepithelial neoplasia after right percutaneous nephroscopic lithotripsy. The patient underwent laparoscopic radical resection of the right kidney and ureter. Based on histopathological and immunohistochemical results, the patient was diagnosed with villous adenoma without adenocarcinoma.
