title: [Case of juxtaglomerular cell tumor (reninoma) treated with laparoscopic partial nephrectomy].
abstract: We report a case of a 22-year-old male with juxtaglomerular cell tumor treated with laparoscopic partial nephrectomy. He was referred to our hospital with hypertension, high concentration of plasma renin activity (PRA) and renal mass. Dynamic enhanced computed tomography showed 17-mm weak contrast-enhancing tumor at the upper pole of the left kidney. Renin suppression and stimulation test revealed autonomous renin secretion although renal venous sampling failed to show significant difference in the PRA between the right and left renal vein. We performed laparoscopic left partial nephrectomy. The histological diagnosis was juxtaglomerular cell tumor. After the operation, his blood pressure and PRA were immediately normalized. Juxtaglomerular cell tumor is an important renal tumor as a curable cause of secondary hypertension.
