For randomization, the blanced block randomization method is used to generate quadruple blocks.According to the randomization method, we expect the two groups to differ by a maximum of 2 people in terms of the number of people assigned. After the methodologist prepares the randomization sequence using the sealdenvelop online site, the generated sequence will be made available to a technician outside the research team. Quadruple blocks (A or B) are placed in envelopes.After the arrival of the first patient with the inclusion criteria, the envelopes are randomly selected and the type of patient group is informed to the research team through a trained technician. Based on the randomly selected envelope, the patient is placed in the (A) double j plus placebo or (B)double j plus potassium citrate treatment group, Blinding description: Patients who have agreed to participate in the study and the therapist for the blinding process, envelopes related to the type of intervention are provided only to the technician. The physician (to avoid bias) and the patient are not informed of the type of intervention (double j plus placebo or double j plus potassium citrate). 3 Urinary stones. Intervention 1: Intervention group: Patients receiving Double j with placebo. Intervention 2: Intervention group: Patients receiving double j in addition to potassium citrate.
