Effects of bladder function exercise on preoperative localization of high-intensity focused ultrasound for uterine fibroids: a randomized controlled trial

Objective: To investigate the efficacy and safety of bladder function exercise in the preoperative localization of high-intensity focused ultrasound ablation (HIFU) in patients with uterine fibroids. Methods From July to December 2021, 110 patients with uterine fibroids who needed preoperative localization of HIFU were included in the study. They were randomly divided into an intervention group and a control group according to the random number table. The intervention group adopted the method of multiple drinking and holding up the urine combined with contracting the levator ani muscle. Patients in the control group drank water and urinated normally, without any other special method guidance and requirements. Results The success rates of preoperative localization and bladder deformation in the intervention group were better than the control group, and the utilization rate of the water sac was lower than the control group (p  0.05). Conclusions The method of multiple drinking and holding up the urine combined with contracting the levator ani muscle can effectively improve the success rate of HIFU preoperative positioning in patients with uterine fibroids and it is safety.
