The Candela pulsed dye laser is safe and effective. Complications are few and related more to the ureteroscopy than to the laser. Current results in the lower ureter utilizing primarily ultrasound as a method of power lithotripsy have been excellent, and it is difficult to see how lasertripsy will improve on these. The importance of the laser is related to its small size and its flexibility. This will permit simpler access to the stone employing instruments such as small-caliber rigid ureteroscopes and small steerable flexible instruments. If these instruments can be passed without ureteral dilatation, access to the stone will be safer, and they may well extend the range of stones regularly susceptible to ureteroscopic removal.
坎德拉脉冲染料激光安全有效。并发症较少，且更多与输尿管镜检查有关，而非激光本身。目前主要利用超声作为动力碎石方法处理输尿管下段结石的效果极佳，很难看出激光碎石如何能在此基础上进一步改善。激光的重要性在于其体积小且具有灵活性。这将允许使用诸如小口径硬性输尿管镜和小型可转向软性器械等工具更简便地接近结石。如果这些器械无需输尿管扩张就能通过，那么接近结石会更安全，并且它们很可能扩大常规可通过输尿管镜取出的结石范围。
