Half of participants will receive collagen/ABMNC scaffold after hysteroscopic adhesiolysis, while the other half will receive Foley catheter balloon.', 'detailedDescription': "Severe asherman syndrome will lead to infertility, and the most common method to treat asherman syndrome is operating to dissect adhesions. In order to prevent the postoperative re-adhesion, many physical isolation measures have been tried. However, they don't improve the microenvironment of endometrial regeneration. It's reported that bone marrow mononuclear cells have good effects on the functional recovery of injured uterus. This study will determine whether collagen scaffolds loaded with autologous bone marrow mononuclear cells will be more effective than Foley balloon catheters at treating infertile women with severe intrauterine adhesions who have taken hysteroscopic adhesiolysis. In addition, the study will be carried out in 2 centers, one is the Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School, the other is Changzhou Maternal and Child Health Care Hospital that is in Jiangsu Province."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT'], 'maximumAge': '40 Years', 'minimumAge': '20 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Having a clear desire to fertility;\n* Infertility that is defined as a women fails to become pregnant after having a normal sex life for two years without contraception.\n* Hysteroscopy examination confirmed intrauterine adhesions(patients who has at least one of the three symptoms which are amenorrhea, hypomenorrhea or infertility, and hysteroscopy or histologic diagnosis of intrauterine adhesions), meeting American Fertility Society diagnostic criteria Ⅱ-III;\n* Normal ovarian function;\n* Regular Menstrual cycles and menstruation is normal before abortion or curettage;\n* BMI\\< 30 kg/m2;\n* Sign a consent form;\n* Follow the test plan and follow-up process.\n\nExclusion Criteria:\n\n* Hereditary diseases;\n* Simple thin endometrium with no uterine cavity adhesion;\n* Simple Uterine scar formation with no uterine cavity adhesion after hysteroscopic adhesiolysis;\n* Contraindications to bone marrow collection or assisted reproductive technology;\n* History of malignant tumor;\n* Other diseases associated with the uterus: uterine fibroids, severe adenomyosis, severe malformations of the uterus;\n* Abnormal blood coagulation, liver and kidney dysfunction, or other diseases which the researchers think may affect the study(such as: uncontrolled hypertension, diabetes, sexually transmitted diseases);\n* With a positive urine pregnancy test；\n* Participating in other clinical studies at the same time;\n* Hysteroscopic adhesiolysis more than 3 times in the past.'}, 'identificationModule': {'nctId': 'NCT02680366', 'briefTitle': 'Treatment of Severe Asherman Syndrome by Collagen Scaffold Loaded With Autologous Bone Marrow Mononuclear Cells', 'organization': {'class': 'OTHER', 'fullName': 'The Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School'}, 'officialTitle': 'A Multi-center, Randomized, Single-blind, Controlled Clinical Trial of Treatment of Severe Asherman Syndrome by Collagen Scaffold Loaded With Autologous Bone Marrow Mononuclear Cells', 'orgStudyIdInfo': {'id': '201600301'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'collagen/ABMNC scaffold', 'description': 'collagen/ABMNC scaffold covered on Foley catheter balloon inserted after hysteroscopic adhesiolysis', 'interventionNames': ['Device: collagen/ABMNC scaffold']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Foley catheter balloon', 'description': 'Foley catheter balloon inserted after hysteroscopic adhesiolysis', 'interventionNames': ['Device: Foley catheter balloon']}], 'interventions': [{'name': 'collagen/ABMNC scaffold', 'type': 'DEVICE', 'description': "The patients will receive a bone marrow puncture to collect bone marrow cells which are used to isolation of ABMNCs.
