Summary

This early study tests whether a steam treatment guided by MRI can safely shrink an enlarged prostate and improve urinary symptoms. About 30 men with moderate-to-severe symptoms who haven't responded well to medication will receive the procedure. Researchers will measure changes in prostate size, symptom scores, and urine flow over 6 months to see if the approach is feasible and safe.
