Clinical significance of bladder training in preoperative localization of high-intensity focused ultrasound ablation of uterine fibroids.

Objectives: High-intensity focused ultrasound (HIFU) is widely used to treat uterine fibroids. HIFU preoperative localization of uterine fibroids can be used to determine whether the patient is a suitable candidate for HIFU treatment. This study investigated the clinical significance of bladder training in improving the success rate of HIFU preoperative localization uterine fibroids.

Material and methods: Our sample consists of patients who planned to undergo HIFU treatment in our hospital but who were failed in previous HIFU preoperative localization. They were recruited between July 2021 and April 2022, and randomly divided into experimental and control groups. A total of 150 patients were enrolled. Each group consisted of 75 patients. The patients in the experimental group adopted the procedure of drinking water multiple times and retaining urine. The training program lasted three days. The patients in the control group were required to keep regular drinking and urination habits without any special instructions or requirements.

Results: There were no statistically significant differences between the two groups in maximum bladder capacity, residual urine volume of bladder, bladder filling levels, and bladder shape change. After bladder training, the maximum bladder capacity and the degree bladder shape change of the patients in the experimental group were improved significantly. The success rate of HIFU preoperative localization in the patients in the experimental group was significantly higher than that of the control group.

Conclusions: Bladder training can effectively improve the success rate of HIFU preoperative localization of uterine fibroids.
