目的:不同的定位系统用不同的卧位方式ESWL治疗输尿管下段结石。方法:将385例输尿管下段结石分为近端、中间端、远端结石。对近端阳性结石选俯卧位X线定位,B超可见的阴性结石选同侧俯卧位B超定位治疗;对中间端和远端的阳性结石,选仰卧位X线定位配合B超监测治疗,B超可见的阴性结石选对侧俯卧位B超定位治疗。结果:碎石率与排石效率显著提高,可达99.7%。结论:分端治疗是取B超和X线二者的优点,能准确、有效定位,疗效提高。
OBJECTIVE: Different positioning systems treat ESR with lower ureteral stones in different supine positions. Methods: 385 cases of lower ureteral stones were divided into proximal, middle and distal stones. On the proximal end of the positive selection of prone position X-ray positioning, B-negative selection of negative stones on the same side of prone position B-positioning treatment; on the medial and distal positive stones, select supine X-ray positioning with B-monitoring, B-visible negative stones in the contralateral prone position B ultrasound treatment. Results: The gravel ratio and stone discharging efficiency increased significantly, reaching 99.7%. Conclusion: The fractional treatment is to take the advantages of both B-and X-ray, which can accurately and effectively locate and improve the curative effect.
