A urinary concrement which appeared in the sigmoid of a 63-year-old man after ureterosigmoidostomy was extracted by endoscopy. The stone was situated proximal to a radiogenic stenosis. Because of the disproportion between the stone and the sigmoidal stenosis, mechanical lithotripsy had to be done before the concrement could be completely extracted.
一名63岁男性在输尿管乙状结肠吻合术后乙状结肠出现的尿路结石经内镜取出。结石位于放射性狭窄近端。由于结石与乙状结肠狭窄不相称，在结石完全取出之前必须进行机械碎石术。
