Comparison of the vault prolapse rate after vaginal hysterectomy with or without residual uterine ligament ligations: A retrospective cohort study

摘要

PurposeTo evaluate the post-hysterectomy vault prolapse (PHVP) rates performed using different methods of vaginal total hysterectomy (VTH).MethodsA total of 251 women who underwent VTH with/without concomitant surgeries between January 1986 and December 2001 in a tertiary center. Thirty-eight women were excluded due to not only a vaginal approach. Of the remaining 213 women, 129 and 84 underwent VTH via the Tsuzi method with residual uterine ligament ligations (ligations group) and traditional VTH (without ligations group), respectively. The χ2and Mann-Whitney U tests were applied appropriately. The cumulative percentages of women without PHVP were calculated over time and compared using Kaplan-Meier curves and log-rank tests. Apvalue of less than 0.05 was considered statistically significant.ResultsCompared to the without ligations group, women in the ligations group had longer operation time (115.9?±?37.1 vs. 103.3?±?41.4?min,p?=?0.002) and more blood loss (217.4?±?137.8 vs. 148.2?±?149.0?mL,p?
