Objective: To summarize the imaging features of yellow granulomatous pyelonephritis. Methods: Intravenous pyelography (IVP), abdominal ultrasonography and CT scan were performed on 15 patients with yellow granulomatous pyelonephritis. The imaging features were analyzed. Results: IVP showed normal in 4 cases, enlargement of renal shadow in 11 cases with varying degrees of impairment of renal function. Abdominal B-ultrasonography showed low echogenicity in 15 cases of renal parenchyma and calculi in 10 cases. CT showed limitations 4 cases, diffuse renal changes in 11 cases, 12 cases of stone shadow. Conclusion: Abdominal B-ultrasound can detect lesions, CT can clearly show diffuse yellow granulomatous pyelonephritis. Yellow granulomatous pyelonephritis diagnosis, combined with clinical data and laboratory tests.
