  1. Representative patient characteristics obtained from medical records are summarized in this table. For each item, we calculated averages and standard deviations, minimal and maximal values, and count data from medical records. “Size of uterus (TVUS)” and “Size of dominant leiomyoma (TVUS)” were measured on admission. The size of the uterus (according to TVUS) was determined by calculating the average length and width of the uterus. The “size of dominant leiomyoma (MRI)” and “size of dominant leiomyoma (TVUS)” were determined by the maximal diameter of the leiomyoma. In some cases, multiple symptoms occurred in a single patient. In the case of allogeneic blood transfusion, we performed transfusion of 6 IU of red blood cell concentrates
