of percutaneous pneumatic nephrolithotomy combined with ultrasound lithotripsy in the treatment of complicated renal calculi. Methods 56 patients with complicated renal calculi were investigated retrospectively, including 43 cases with unilateral calculi, 13 cases with bilateral calculi, 48 cases with staghorn calculi,18 cases with pyonephrosis. The longitudinal size of calculi was 5-8 cm.Working channel for percutaneous nephroscopy was established under the guidance of B ultrasonography. Renal stones were fragmented and extracted with the EMS 3.Results The mean operation time was 50 minutes(30-120 minutes). The clearance rate of stone in one session was 80.3%, residual stones were treated by EWSL,the stones were discharged completely. Conclusion The percutaneous pneumatic nephrolithotomy combined with ultrasound lithotripsy for complicated renal calculi is characterized by high efficiency, safety and minimal invasion.Key words: renal calculus; percutaneous nephroscopy; ultrasound; lit

【摘要】目的 应用高频超声及彩色多普勒血流显像观察视网膜脱离的形态、部位、范围及视网膜中央动脉（CRA）的血流动力学变化。方法 应用二维超声及彩色多普勒血流显像分别对 40例正常人（39只正常眼）和40例视网膜脱离患者（41只患病眼）进行视网膜脱离光带

急性阑尾炎是外科常见病是最多见的急腹症，发病率约为0.1%。虽然阑尾炎的诊断较易，但有时阑尾症状表现不典型和阑尾位置变异后难免误诊。随着超声技术不断提高，可以直观的显示病变的阑尾，为临床诊断急性阑尾炎及手术时取切口位置大小提供有价值的资料。现

近年来，随着人们生活水平的提高，抵抗力的增强，肝脓肿的发病率有明显下降趋势。现将我院2005年～2009 年期间收治的36例经B超诊断的肝脓肿患者的临床资料进行回顾性分析，以探讨超声诊断肝脓肿的价值。 1资料与方法 1.1一般资料:36例肝脓肿患者，均经手术及
