Objective To investigate whether the high intensity focused ultrasound (HIFU) for treating uterine fibroids and adenomyosis leading to pelvic adhesion .Methods 1 672 patients with definitely diagnosed uterine fibroids or adenomyosis were col‐lected and divided into the non‐HIFU group(1 560 cases) and HIFU group(112 cases) according to whether performing HIFU op‐eration .The pelvic adhesion situation in each case was scored according to pelvic adhesion scoring system .Then the results were performed the statistical process .Results No statistically significant differences were observed in the pelvic adhesion situation and pelvic adhesion degree between the HIFU group and the non‐HIFU group (P>0 .05) .The single factor analysis of factors possibly causing pelvic adhesion showed that the age ,past history of endometriosis ,operation and pelvic inflammatory disease ,lesion size and dysmenorrhea history affected pelvic adhesion ,the differences were statistically significant(P<0 .05) .But in the multi‐factor corre‐lation analysis ,various factors in the HIFU group were excluded(P> 0 .05) ,while the operation history and pelvic inflammation disease history had correlation with pelvic adhesion (P<0 .05) .Conclusion HIFU dose not cause pelvic adhesion in treating uter‐ine fibroids and adenomyosis .

Randomized controlled trial(RCT),considered as the strongest evidence-based method in clinical trial,can provide first-hand scientific evidence for clinical practice and instruct clinicians to make correct decisions in practice.This article introduces the principles for RCT designing,analyzes the common problems concerning RCT in clinical practice and the common mistakes made in RCT statistical methods.It is concluded that application of RCT method and correct statistical methods are of great importance in clinical medical research.
