NCT04997668

Brief Summary

To compare intraoperative as well as postoperative outcomes of SOLTIVE Thulium laser compared to Ho:YAG laser for the treatment of urolithiasis. The hypothesis is that utilizing the SOLTIVE Thulium laser for the treatment of urolithiasis will result in a more efficient procedure, with comparable stone free rate to that of Holmium laser and subjective improvement in physician satisfaction.
