[A Case of Partial Nephrectomy for Juxtaglomerular Cell Tumor in the Renal Hilum]

We report a case of a 27-year-old pregnant woman with juxtaglomerular cell tumor of the renal hilum treated by partial nephrectomy. Hypertension had been diagnosed prior to conception and she had been receiving antihypertensive treatment. Hyperreninemia was noted during pregnancy, and postpartum computed tomography revealed a nodule approximately 15 mm in size in the right renal portal region. The nodule was suspected to represent juxtaglomerular cell tumor, a benign tumor that presents with secondary hypertension. We performed open partial nephrectomy, which eliminated the need for antihypertensive treatment and preserved renal function.
