摘要

With the development of smaller caliber uretero-scopes and the introduction of improved instrumentation, including the holmium:YAG laser, ure-teroscopy has evolved into a safer, more effective treatment modality for ureteral stones. Nevertheless, many unanswered questions remain on the proper approach to optimize stone-free status and minimize periprocedural patient discomfort in this revolutionary ureteroscopic era.
