Abstract:
Objective To explore the value of pelvic fascia changes after high intensity focused ultrasound (HIFU) ablation of uterine fibroids patients with MRI.Methods The pelvic MRI and clinical data of 283 patients with uterine fibroids after treatment of HIFU were analyzed retrospectively.The total power and irradiation time of HIFU,and the degree of pelvic fascia edema changes were observed.The correlation between age,fibroids location,type,number,volume,total energy,irradiation time of HIFU and the degree of pelvic fascia edema were analyzed.Results Totally 201 patients (201/283,71.02％) had pelvic fascia edema and 59.71％ (169/283) were degree 1 and 2.There was significant difference in the degree of pelvic fascia edema in patients with different fibroids (x2 =27.50,P=0.007).There was no correlation between patients age,number,volume,type of fibroids,nor pelvic fascia edema (all P＞0.05).HIFU energy and irradiation time were positively correlated with the degree of pelvic fascia edema (rs =0.288,0.317,both P＜0.001).Conclusion MRI can observe pelvic fascia edema caused by HIFU treatment of uterine fibroids.HIFU irradiation time,total energy,and location of uterine fibroids location are the main influencing factors.
