Objective: A metaanalysis of randomized trials was conducted to evaluate if the type of hysterectomy, total abdominal hysterectomy or supracervical hysterectomy, has an impact on the development of urinary incontinence.
Study design: We searched MEDLINE, EMBASE, CINAHL, Biological Abstract, and the Cochrane Library up to February 2007; abstracts at major meetings and bibliographies of retrieved articles were scanned. A fixed effect model was used to calculate summary relative risk estimates and 95% confidence intervals (CIs).
Results: Analysis showed no statistical difference in the risk of developing stress or urge urinary incontinence in women who underwent supracervical hysterectomy compared with women who underwent total abdominal hysterectomy (relative risk, 1.3; 95% CI, 0.94-1.78; P = 0.16 and relative risk, 1.37; 95% CI, 0.77-2.46; P = .25).
Conclusion: There is no statistical evidence of a different risk for developing either stress or urge urinary incontinence after a supracervical hysterectomy or a total hysterectomy.
