Detaljert beskrivelse
This study aims to assess the feasibility, procedural characteristics, and early safety of MRI-TRUS fusion-guided planning and delivery of Rezūm water vapor therapy in men with symptomatic benign prostatic hyperplasia.
Eligible patients with prior MRI prostate fulfilling the eligibility criteria will be enrolled from the participating hospitals. Baseline assessment including symptom severity and uroflowmetric measurements, urine culture will be performed in the usual routine pre-Rezūm nurse-led clinics. The intervention will consist of MRI segmentation and image-informed injection planning, with documentation of planned and delivered injection sites and performance metrics. .
