Abstract: Objective To discuss an ideal diagnostic method of young children′s vaginal foreign bodies, and to appeal for the high attention from society and family on preschool children′s mental health. Methods Retrospective analysis was conducted on four young children admitted in the Pediatric Surgery Department of the Second Affiliated Hospital of Xi′an Jiaotong University from January 2015 to December 2016. Four children′s vaginal foreign bodies were diagnosed by ultrasound and demonstrated after operation. Their clinical manifestation and ultrasonographic features were analyzed. A qualitative research method for describing the phenomenon was employed. Through interviews, children and their parents' psychological behaviors were analyzed and then the related influencing factors of mental health were determined. Results The leading symptoms of vaginal foreign bodies were children′s vaginal bleeding and abnormal secretion. By abdominal and perineal ultrasonic examination, endovaginal abnormal hyperecho and purulent secretion were observed. The Results of psychological behavior analysis revealed those four children belonged to the slowly-warm-up temperament. Meanwhile, they were in the preschool period in which it is vital for executing early sex education. Nevertheless, their parents were generally in low education level. Both of the children′s parents and schools did not pay attention on the sex education to young children, which was the significant cause of the occurrence of vaginal foreign bodies. Conclusions Ultrasonic examination is an ideal means to diagnose young children′s vaginal foreign bodies. Family and school lack sex education to young children, leading to impact on their mental health, thereby causing behavioral problem like vaginal foreign bodies.
