目的提高超声对输尿管结石的诊断符合率。方法回顾性分析2008年至2009年收治的96例输尿管结石患者的超声影像学表现。结果输尿管结石90%是肾内形成而排入输尿管的,结石容易停滞或嵌顿在输尿管狭窄部位,输尿管结石90%以上在下1/3段,其次为中1/3段。直径不到5 mm的输尿管结石可自动排出。结石嵌顿于输尿管出现近端输尿管扩张和同侧肾积水,绞痛并向内侧放射,伴镜下血尿。输尿管膀胱段结石可伴有尿频、尿急、尿痛。结论超声诊断输尿管结石具有方法简便、诊断迅速、无创伤、无痛苦等优点,为临床选择治疗方案提供了可靠依据。
Objective To improve the accuracy of ultrasonic diagnosis of ureteral calculi. Methods We retrospectively analyzed the ultrasound imaging findings of 96 patients with ureteral calculi treated from 2008 to 2009. Results 90% of ureteral calculi were formed in the kidney and discharged into the ureter, stones easily stagnated or incarcerated in the ureteral stricture, more than 90% of ureteral stones in the next 1/3, followed by 1/3 of the. Ureteral stones less than 5 mm in diameter are automatically drained. Stone incarcerated in the proximal ureteral ureter expansion and ipsilateral hydronephrosis, angina and radiation to the inside, with microscopic hematuria. Ureteral calculi may be associated with urinary bladder stones, urgency, dysuria. Conclusion Ultrasound diagnosis of ureteral calculi has the advantages of simple method, rapid diagnosis, no trauma and no pain. It provides a reliable basis for the clinical choice of treatment.
