输尿管结石急性梗阻伴肾包膜下积液的声像表现及其临床意义

目的:探讨输尿管结石急性梗阻伴肾包膜下积液的声像表现及其临床意义.材料和方法:对30例声像图表现为输尿管结石急性梗阻伴肾包膜下积液的病例进行回顾性分析.结果:肾包膜下积液多发生于肾的上、下两极,上极4例,下极28例(其中包括上、下两极均发生积液的病例2例).积液以积液的最大切线宽度估测为2～30mm,呈带状、三角形或梭形,同时伴有肾轻度积水.结石梗阻部位多位于输尿管下段,结石的最长径<10mm.结论:输尿管结石急性梗阻伴肾包膜下积液有其特征性声像表现,超声检查可以及时明确诊断,有效的指导临床治疗.

The Ultrasonographic Features and Clinical Values of Dropsy under Capsula Fibroso Associated with Acute Ureterolithiasis

Purpose: To study the ultrasonographic features and the clinical value of dropsy under capsula fibroso associated with acute ureterolithiasis. Materials and Methods: Ultrasonic features in 30 patients with acute obstructive ureterolithiasis were retrospectively reviewed. Results: Four dropsy under capsula fibroso were located in the upper and 28 in lower pole of the kidney .The width of liquid measured at the maxium tangent line was 2mm to 30mm.The dropsy was accompanied by slighter hydronephrosis and was band, triangle or fuciform in shape.Most obstructive sites of caculi was located in the inferior segment of ureter.The longest dimension of calculus was less than 10mm. Conclusion: The ultrasonographic features of dropsy under capsula fibroso is of characteristic and of value in the clinical diagnosis and therapy of acute ureterolithiasis.
