To determine the prognostic variables effecting the successful pregnancy outcome of reversal of sterilization.
Demographic and clinical history data were collected prospectively.
Division of Infertility and Reproductive Endocrinology, Department of Obstetrics and Gynecology, University of British Columbia, Vancouver, Canada.
Between 1981 and 1992, 217 consecutively referred patients underwent reversal of sterilization by a single surgeon using microsurgical techniques.
Prognostic variables associated with success were examined using logistic regression and expressed as odds ratios with corresponding 95% confidence intervals.
Age at reversal was a significant factor with the odds of a successful outcome for those < or = 35 years compared with those > 35 years being 2.3 with a 95% confidence interval of 1.3 to 4.1. There was some evidence that average tubal length as categorized in 2-cm intervals was a significant prognostic factor with the odds of a successful outcome for those with an average length of > 4 cm to those < or = 4 cm being 5.3 with a 95% confidence interval of 1.4 to 20.0.
Nonsubjective analysis of the prognostic variables of reversal of sterilization associates only age and tubal length of > 4 cm with intrauterine pregnancy.
确定影响绝育逆转成功妊娠结局的预后变量。
前瞻性收集人口统计学和临床病史数据。

1981年至1992年间，217例连续转诊患者由一名外科医生采用显微外科技术进行绝育逆转手术。
使用逻辑回归分析与成功相关的预后变量，并以比值比及相应的95%置信区间表示。
逆转时的年龄是一个重要因素，35岁及以下患者成功妊娠的几率与35岁以上患者相比为2.3，95%置信区间为1.3至4.1。有证据表明，以2厘米间隔分类的平均输卵管长度是一个重要的预后因素，平均长度大于4厘米的患者与平均长度小于或等于4厘米的患者相比，成功妊娠的几率为5.3，95%置信区间为1.4至20.0。
对绝育逆转预后变量的客观分析表明，只有年龄和输卵管长度大于4厘米与宫内妊娠有关。
