Preoperative Diagnosis of Juxtaglomerular Cell Tumors in Eight Patients

The aim of this study was to improve the diagnostic efficiency for juxtaglomerular cell tumors ( JCT s) and to determine whether clinical and magnetic resonance imaging features can help to differentiate JCT s from clear cell renal cell carcinoma (cc RCC ). The clinical features of eight patients with JCT s and 27 patients with cc RCC s were analyzed. A flow diagram for young people with hypertension was applied to facilitate the diagnosis. Clinical presentations were analyzed, including age, hypertension, and hypokalemia. The results of our study produced a flow diagram that narrowed the scope of diagnosis. The statistical results demonstrated that patients with a renal mass aged 14 to 30 years, had grade 3 hypertension, or had moderate hypokalemia had a greater possibility of having a JCT than a cc RCC ( P <.0000, P <.01, P <.0005, respectively). In addition, the flow diagram and magnetic resonance imaging features were useful to distinguish JCT s from other renal tumors.
