Rezum for 30-80ml Patients With Moderate-severe LUTS to Study Surgical Principles for Median Lobe Enlargement

Not Applicable
Recruiting
Conditions
Prostatic Hyperplasia of the Medial Lobe
Interventions
Device: Rezum®
Registration Number
NCT06177821
Lead Sponsor
Seoul National University Hospital
Brief Summary

This study was created to determine the safety and efficacy of treating prostatic hyperplasia with or without prominent median lobe enlargement with the REZUM technique. The systematic implementation of decisions for the location, vapor time, and the number of injections contributes to the Rezum procedure configuration for the median lobe treatment being safer and standardizer.
