The diffuse retroperitoneal extravasation of urine most often secondary to an ureteric calculus may present as a surgical emergency with localized or general abdominal symptoms. As the clinical signs are intriguing, history and a blurred psoas shadow on the plain film of the abdomen are the best guides to the right diagnosis definitely confirmed by an intravenous urography. Management usually is conservative and the recovery most often uneventful.
尿液弥漫性腹膜后外渗最常见于继发于输尿管结石，可能表现为外科急症，伴有局部或全腹症状。由于临床体征令人困惑，病史和腹部平片上模糊的腰大肌阴影是正确诊断的最佳线索，静脉尿路造影可明确确诊。治疗通常采用保守治疗，大多数情况下恢复顺利。
