With the referral of each patient, one of the envelopes will be randomly selected by the patients and will be introduced as a study group. The stratification approach is not used. Concealment will not take place in the study. 2-3 ureteral stones. Intervention 1: Intervention group: In the first group (holmium laser) after spinal anesthesia, in lithotomy position uretroscopy and lithotripsy will be done by laser fiber and if necessary double j will be inserted. Intervention 2: Control group: In the second group (pneumatic) after spinal anesthesia, in lithotomy position uretroscopy and lithotripsy will be done by pneumatic lithotriptor and if necessary double j will be inserted.
