The primary questions it aims to address are:\n\nCan precise prostate thermal vapor ablation under MRI/TURS guidance effectively treat benign prostatic hyperplasia (BPH) and alleviate lower urinary tract symptoms (LUTS)? What safety issues may arise in participants after undergoing prostate thermal vapor ablation? Study Procedures Participants Preoperative Evaluation: Participants will undergo comprehensive preoperative assessments, including clinical examinations and laboratory tests.\n\nProcedure: Participants will receive precise prostate thermal vapor ablation under MRI/TURS guidance.\n\nPostoperative Follow-up:\n\nRegular follow-up to reassess prostate volume. Periodic completion of the International Prostate Symptom Score (IPSS) questionnaire.\n\nRegular measurement of maximum urinary flow rate (Qmax) and post-void residual urine volume (PVR).\n\nResearch Team The research team will conduct precise prostate thermal vapor ablation under MRI/TURS guidance for the participants and manage their follow-up assessments.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '45 Years', 'genderBased': True, 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age 45-85 years;\n* International Prostate Symptom Score (IPSS) ≥ 8, indicating moderate to severe Lower Urinary Tract Symptoms (LUTS) that significantly impact quality of life;\n* Poor response to pharmacological treatment or refusal of pharmacological treatment;\n* Prostate volume 30-80 mL;\n* Maximum urinary flow rate (Qmax) \\< 15 mL/s;\n* Post-void residual urine volume (PVR) \\< 300 mL;\n* Willingness to provide informed consent and participate in postoperative follow-up.\n\nExclusion Criteria:\n\n* Prostate volume \\< 30 mL or \\> 80 mL;\n* Severe urinary tract infection;\n* Preoperative definitive diagnosis of prostate cancer;\n* Known neurogenic bladder, detrusor muscle weakness, urethral stricture, or other non-BPH causes of urinary obstruction;\n* Patients with prostatitis;\n* History of invasive prostate interventions, such as radiofrequency ablation, laser therapy, or microwave treatment;\n* Patients with severe cardiovascular disease, chronic obstructive pulmonary disease, severe diabetes, hepatic or renal dysfunction, or systemic bleeding disorders, as assessed by the investigator to be unsuitable for surgery.'}, 'identificationModule': {'nctId': 'NCT06817733', 'briefTitle': 'Clinical Study on Prostate Thermal Vapor Ablation Guided by MRI/TRUS Fusion Imaging', 'organization': {'class': 'OTHER', 'fullName': 'Chinese PLA General Hospital'}, 'officialTitle': 'Clinical Study on Prostate Thermal Vapor Ablation Guided by MRI/TRUS Fusion Imaging', 'orgStudyIdInfo': {'id': 'REZUM2025'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Rezum', 'description': 'Participants in this group will undergo transurethral thermal vaporization of the prostate.', 'interventionNames': ['Procedure: Transurethral Thermal Vaporization of the Prostate']}], 'interventions': [{'name': 'Transurethral Thermal Vaporization of the Prostate', 'type': 'PROCEDURE', 'description': 'After anesthesia, the patient is placed in the lithotomy position, and standard aseptic preparation and draping are performed.
