Determining the effectiveness of exosome injection compared to sterile water at the scar site during cesarean section on niche size in women with a previous cesarean section
Determining the effectiveness of injecting exosomes into cesarean scar in women with a history of one previous caesarean section
Design
This is a randomized triple-blind ,placebo control, phase 3 clinical trial involving a total of 60 patients. For randomization, 30 "A" labels and 30 "B" labels will be placed inside some envelopes and then in a box. For each patient an envelope is drawn out of the box. The physician, the patients, and the data analyst are be blinded to groups assignments.

Intervention group (exosome): during cesarean after delivering baby, uterine incision will be repaired by vicryl 1 and exosomes injected in the site of scar.
Control group (sterile water): during cesarean after delivering baby, uterine incision will be repaired by vicryl 1 and strile water injected in the site of scar.
Main outcome variables
Niche size based on transvaginal sonogram at 6th week post operation

Randomization (investigator's opinion)
Randomized
Randomization description
Random allocation rule: At first, on special unmarked papers, 30 A letters and 30 B letters are written. Then all (60) are placed in a bag and for each patient, after obtaining informed consent, a paper is taken out randomly without replacement. Based on the letter written on it, the intended intervention is performed on the patient. In addition, interventions A (exosome injection) or B (sterile water injection) are determined by lottery.
Blinding (investigator's opinion)
Triple blinded
Blinding description
Patients and physician are blinded regarding the groups ( exosomes or sterile water injection ,that are the same regarding appearance and form), and analyzer only sees the codes in data sheet and is blinded regarding.
