A retrocaval ureter Yang Yong, Huan Yi, Ji Gang

A 60-year-old man presented with a 30-year history of back pain which had worsened over 3 days. Pain on percussion of the right lumbar region was evident on physical examination. Urinalysis was negative for red blood cells, white blood cells, or protein. CT was done and the images were reconstructed. The A
