Abstract: 【Abstract】 Objective: to evaluate the clinical features and key points in treatment of ovarian torsion in children. Methods: data of 64 children were analyzed retrospectively. Results: seven to twelve years old is the high incidence age of ovarian torsion. Most of the patients manifested typical lower abdominal cramps. unilateral non-homogeneoous mass in pelvic by color doppler ultrasound test often suggests ovarian torsion. All the patients underwent laparoscopic surgical exploration firstly. All but 5 cases with ovariectomy were treated conservatively successfully with normal size and function of ovarian. Conclusion: ovarian torsion in children is not commonly encountered clinically. Lacking of typical clinical manifestation, it is easily misdiagnosed. Once the diagnosis is identified, a surgical exploration is mandatory. The options of treatment to a twisted ovarian depends on ischemic time, extent of ischemia and characteristic of the leision.
