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.

McGill Pain Questionnaire
The interpretation of the questionnaire is pretty basic: the higher the score, the higher the pain level. The maximum score an individual can reach on the MPQ is 78. According to the questionnaire, a person with a score of 0 effectively does not experience pain.
