Hysteroscopic adhesiolysis with uterine cavity reconstruction is the standard treatment, but women with moderate to severe IUA still have high rates of re-adhesion and unsatisfactory endometrial repair after surgery.\n\nInjectable platelet-rich fibrin (i-PRF) is an autologous blood-derived biologic material that can be prepared at the bedside. Compared with conventional platelet-rich plasma, i-PRF may provide a more sustained release of growth factors and form a fibrin scaffold after intrauterine administration, which may help protect the wound surface, support endometrial regeneration, improve blood perfusion, and reduce postoperative re-adhesion.\n\nThis prospective randomized controlled study will evaluate the efficacy and safety of intrauterine i-PRF perfusion in women with moderate to severe IUA after hysteroscopic adhesiolysis. Participants will be assigned to receive either i-PRF intrauterine perfusion or sodium hyaluronate intrauterine treatment after surgery. The study will compare postoperative uterine cavity recovery, endometrial thickness and blood flow, clinical pregnancy outcomes, and safety events. The goal is to determine whether i-PRF can improve endometrial regeneration and reproductive outcomes and provide evidence for an optimized postoperative treatment strategy for moderate to severe IUA.",[28],"Intrauterine Adhesions",[28,30,31,32],"TCRA","Platelet-Rich Plasma","RCT","NOT_YET_RECRUITING","2026-04-12",{"date":36,"type":37},"2026-04-17","ACTUAL",{"date":39,"type":22},"2026-05-01",{"date":41,"type":22},"2029-06-30",{"name":43,"class":44},"Beijing Obstetrics and Gynecology Hospital","OTHER",""]
