About this trial
This research study is being conducted to assess the ability and efficiency of two laser systems to break up kidney stones during ureteroscopy with laser lithotripsy for kidney stone treatment.

Must be a suitable operative candidate for flexible ureteroscopy per American Urological Association guidelines
Must be able to give consent
Bilateral ureteroscopy will be permitted but only the first side (per surgeon discretion) will be included in the study
Disqualifiers

Prior ipsilateral upper urinary tract reconstructive procedures or history of ipsilateral ureteral stricture
Prior radiotherapy to the abdomen or pelvis
Neurogenic bladder or spinal cord injury
