[Current role of the Zeiss extractor catheter. Comparative study with other methods. Presentation of 80 personal...

The present study compared the Zeiss and Dormia type extractors for ureteral calculi with the new methods of treatment (shock waves and laser) to determine the place of these extractors in our urological armamentarium today. The results and the complications in our series comprised of 80 cases are presented and the literature available on this subject reviewed. We discuss briefly the methods commonly used today, i. e., shock waves and laser, with special reference to the good results and scant complications. We can conclude from this study that these catheters continue to be useful in current urological practice.
