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
images showed that the upper part of the right ureter was dilated and the portion lying behind the inferior caval vein was tapered as a result of compression, leading to hydronephrosis of the right kidney (ﬁgure). Following surgical intervention, the patient’s condition improved. B
