1. Prepare tools and materials for the research.
2. Align perceptions with the research team to conduct well-guided interviews.
3. Patients who meet the inclusion and exclusion criteria will be given an explanation and a research information sheet and asked for consent to participate in the study.
4. Subjects who agree to participate in the study will then undergo a urogynecological medical record and gynecological physical examination, pelvic floor muscle strength, and POP Q.
5. Randomization of study subjects will be performed.
6. Participants are unaware of whether they would receive PRP therapy or a placebo.
7. The study subjects were hospitalized in preparation for surgery, in accordance with the regulations of the hospital where the study subjects were located.
8. PRP was prepared from the patient's own blood on the day of surgery. Blood was drawn no later than one hour before surgery. Twenty milliliters of blood was collected for processing into PRP.
9. Participant undergo pelvic organ prolapse surgery as a medically indicated treatment for pelvic organ prolapse.
10. Punch biopsies were performed on the anterior vaginal mucosa located in the Fascia Pubocervicalis area, 6 mm deep. The tissue was sent in a special medium to the Anatomical Pathology Laboratory of Dr. M. Djamil General Hospital.
11. PRP or placebo injections were administered based on a random number sequence determined by block randomization among subjects undergoing POP surgery in the Surgical Unit of the hospital where the study subjects were located.
12. The PRP preparation was placed in a 5 cc syringe.
13. The placebo preparation, containing NaCl solution, was placed in a 5 cc syringe.
14. The injection was performed by the POP surgery operator into the anterior vaginal wall to a depth of approximately 1-1.5 cm, estimating the location of the Fascia Pubocervicalis.
15. Further observation was conducted 8 weeks after surgery, involving punch biopsies of the anterior vaginal mucosa from three sites. These were then sent on special media to the Anatomical Pathology Laboratory of Dr. M. Djamil General Hospital for examination of the type I/III collagen ratio, MMP-2, and MMP-9.
