A comparative study of female sterilization via modified Uchida and silver clip techniques in rural China

ObjectiveTo compare the specific effects of 2 female sterilization methods: the modified Uchida technique and the application of silver clips.MethodsA total of 2198 women living in rural areas who were still of reproductive age but opting for sterilization were enrolled. The participants were randomly divided into 2 groups, and underwent sterilization by either modified Uchida technique or silver clips. Information on acceptability, operation conditions, effectiveness, adverse effects, and complaints was collected 3, 6, and 12 months after the procedure.ResultsNo significant difference in effectiveness, adverse effects or chief complaints between the 2 procedures was found. Differences in operative outcome, bleeding volume during the procedure, and operation time were found.ConclusionA shorter operation time and less bleeding for the silver clip method indicated that female sterilization by this technique was as safe as that by modified Uchida technique.
