Abstract
This study intended to assess the urinary retention between nerve-sparing radical hysterectomy and radical hysterectomy in cervical cancer. Relevant studies were selected from databases of PubMed, Embase, Wanfang, and China National Knowledge Internet with the last report up to January 15, 2022. Hazard ratio (HR) and 95% confidence interval (CI) were chosen as the evaluation index. Heterogeneity was assessed using Cochran Q test and I2 test. Subgroup analysis was conducted based on areas and cancer types (primary and metastatic cancer). A total of 8 articles (retrospective cohort studies) were selected in the meta-analysis. There were significant correlations between nerve-sparing radical hysterectomy and radical hysterectomy in related with urinary retention (HR [95% CI] = 1.78 [1.37, 2.31], P < .001) and (HR [95% CI] = 2.49 [1.43, 4.33], P = .001) of cervical cancer patients. Egger test revealed a significant publication bias (P = .014). Sensitivity analysis via omitting 1 study at each time showed that omission of any study made significant difference (P < .05), indicating reliability and good stability for the analysis. Additionally, there were significant heterogeneities in most subgroups.
