Significance of preoperative calculation of uterine weight as an indicator for preserving the uterus in pelvic reconstructive surgery.

Recently, increasing evidence has shown that uterus preservation is beneficial for pelvic organ prolapse (POP) patients, both physiologically and psychologically. However, the preoperative indicators for uterus preservation have rarely been examined. The current study was designed to determine the relationship between the preoperative evaluated uterus weight and the operation selection (preserving the uterus or not) in pelvic reconstructive surgery (PRS) using vaginal meshes. First, in a series of 96 patients undergoing hysterectomy, the uterine weight was calculated by preoperative ultrasound measurements, and was then compared with the postoperative actual weight of the uterus. Subsequently, in a series of 65 patients undergone PRS using vaginal meshes and preserving the uterus, the uterine weight was calculated by preoperative ultrasound measurements. Lastly, in a series of 43 patients with a uterine weight > 56.12 g who had undergone PRS using vaginal meshes, the operation success rate in patients with a preserved uterus was compared to patients for whom the uterus was not preserved. The results showed that uterus weight can be evaluated by ultrasound and used as a preoperative indicator for whether the uterus should be preserved or not in PRS when using vaginal meshes. It was indicated that preoperative evaluation of uterine weight is beneficial for surgical planning and guidance.
