    Abstract:
    OBJECTIVE: The objective of the study was to assess whether cervical preservation at the time of hysterectomy may help prevent subsequent apical vaginal vault prolapse. STUDY DESIGN: Supracervical hysterectomies were performed in 12 unembalmed cadavers. Successive hanging weights of 1, 2, 3, and 4 kg were loaded against the cervical stump and distances moved were recorded. The same process was repeated after completion of a total hysterectomy. RESULTS: Average distances pulled with 1, 2, 3, and 4 kg of traction against the cervical stump were 17.8 +/- 1.9, 24.1 +/- 2.5, 29.0 +/- 2.8, and 34.3 +/- 3.5 mm, respectively. After total hysterectomy, these distances were 17.5 +/- 2.5, 23.5 +/- 2.6, 29.3 +/- 3.1, and 34.5 +/- 3.6 mm, respectively. CONCLUSION: In unembalmed cadavers, it appears that total abdominal hysterectomy and supracervical hysterectomy provide equal resistance to forces applied to the vaginal apex.
