In this study, the investigators summarize the existing best evidence of intermittent catheterization in patients after radical cervical cancer surgery from the perspective of clinical translation of evidence through systematic search, evaluation and evidence integration, construct a nursing protocol of intermittent catheterization for patients after radical cervical cancer surgery based on the best evidence combined with the clinical context, and explore the clinical application effect of the above nursing protocol. It will provide a reference basis for the development of the standardization and management of intermittent catheterization for postoperative patients with cervical cancer in China, as well as the development of guidelines for intermittent catheterization after radical cervical cancer surgery.
