体外震波碎石治疗尿路结石已在我国广泛开展,有关论文也日渐增多。鉴于各种机型或各家医院治疗效果的比较,或各种治疗方法对比的需要,迫切需要有一种客观的统一指标。为此,我们试就以下几项指标制订和提出初步意见,以便进一步探讨。一、结石面积的测量和描述目前,临床判断尿路结石的大小,绝大多数仍以X线片上结石的阴影为测量依据。由于X线投影与距离的影响,通常X线片中结石阴影较实际体积增大1.1～1.2倍。传统习惯描述结石大小时,往往是提及结石的直径数据,但是,实际结石并非完全
Extracorporeal shock wave lithotripsy treatment of urinary tract stones has been widely carried out in our country, the papers are also increasing. In view of the comparison of the treatment effects of various models or hospitals, or the comparison of various treatment methods, there is an urgent need for an objective and unified indicator. To this end, we try to develop and put forward preliminary opinions on the following indicators for further discussion. First, the measurement and description of stone area At present, the clinical judgment of the size of urinary tract stones, the vast majority are still X-ray films on the shadow of the measurement basis. Due to the influence of X-ray projection and distance, the stone shadow in X-ray film usually increases 1.1 ~ 1.2 times than the actual volume. Traditionally, when describing the size of a stone, it is often the diameter data that refers to the stone, however, the actual stone is not complete
