Open prostatectomy has a higher risk of bleeding and slower postoperative recovery, with a higher probability of requiring blood transfusion. The incidence of urinary incontinence after transurethral enucleation ranges from 3.33% to 20%, possibly due to excessive traction and compression on the external urethral sphincter, leading to partial muscle fiber rupture. The rate of erectile dysfunction after enucleation is 8.82%, while retrograde ejaculation occurs in 6.37% of cases, especially for patients with larger prostates. Once these complications occur, they are often difficult to recover from and severely impact the patient's quality of life. In our center, the technique of Rezum has been further improved by incorporating ultrasound and MRI imaging guidance. The investigators design a reasonable and comprehensive ablation plan that ensures accurate positioning of enlarged prostate glands for complete and thorough ablation while ensuring efficacy and safety. The optimized methods mainly include ablation optimization and combined imaging techniques."}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '45 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
