作者应美国哈佛大学医学院和贝勒医学院之邀于1983年9月至1984年10月到两学院泌尿外科研究和进修。这两所学院是美国和世界有名的学府。此行主要是全面比较两国泌尿外科的差距,学习他们在医疗技术、教学、科研方面的先进经验,同时进行一些交流。以下结合两学院情况重点介绍泌尿外科几项主要发展。一、泌尿系结石这些年来在治疗方面发生了根本性的突破,如西德道尼尔公司发明制造的体外振动波碎石机碎石术和西德、美国制造的经皮肾镜、肾输尿管镜、超声和液电碎石,直视套篮取石术。体外振动波碎石术是病人躺在一温水槽内,槽底部有一电极管,放电的电波通过水,其振动波产生第二焦点;用两交叉 At the invitation of the Harvard Medical School and Baylor College of Medicine, the authors visited Urology Institute of Urology and Advanced Studies from September 1983 to October 1984. The two colleges are well-known in the United States and the world. This trip is mainly to fully compare the gap between urology in both countries and to learn from their advanced experience in medical technology, teaching and research, and to conduct some exchanges at the same time. The following combination of two colleges highlight some major urological development. First, urinary stones over the years in the treatment of a fundamental breakthrough occurred, such as the company invented and manufactured by West Germany Neil Vibroscope lithotripsy lithotripsy and West Germany, the United States made by percutaneous nephrolithotomy, renal ureter Mirror, ultrasound and electrohydraulic lithotripsy, straightening the basket lithotomy. Vibration wave lithotripsy is a patient lying in a warm water tank, the bottom of the tank has an electrode tube, the discharge of radio waves through the water, the vibration wave to produce the second focus; with two cross
