Abstract

In a randomized trial, 93% of cryoablation patients who were evaluated at both 12 and 24 months and not retreated were free of abnormal uterine bleeding at 12 months and 94% at 24 months versus 92% of electroablation patients at both times. The retreatment rate was similar after cryoablation (12.9%) and electroablation (14.0%).
