The results of laparoscopically associated vaginal hysterectomy (LAVH) in our hospital shows that removed uterus of over 800g in weight produces significantly raised operative blood loss. Removed uterine weight is an important decision factor for hysterectomy. Therefore, we conducted this study to achieve a more reliable preoperative uterine weight estimation using MRI.
We compared the results from two methods of estimation for 135 total hysterectomy cases: Method A _??_ estimation based on three parameters including the distance from uterine apex to external os using preoperative MRI; method B -estimation based on the sum of products of diameters in three directions of the biggest three myoma nodes. The equation of regression of the removed uterine weight (y) obtained by method A is y=0.503x-35.9 (x=a×b×c) and that obtained by method B (y) is, y=0.604x+249 (x=sum of a×b×c) from method B.Both equations of regression have significant correlations between estimated uterine weight and removed uterine weight.
These equations to estimate uterine weight will contribute to the decision of approach
