Value of transrectal three-dimensional ultrasound in diagnosis of polycystic ovarian syndrome in virgin patients / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the diagnostic value of transrectal three-dimensinal ultrasonography for virgin polycystic ovarian syndrome(PCOS) patients.Methods Transrectal three-dimensional ultrasonography were performed on 45 virgin patients with PCOS,30 with polycystic ovary(PCO) and 25 controls.Ovarian follicle numbers(FN),ovarian volume(OV),ovarian stroma area(SA),total area(TA) and SA/TA ratio and correspondent biochemical parameters were measured.Results Transrectal ultrasonography was more reliable than abdominal ultrasonography in the detection of delicate structure of ovary in virgin patients.This method was noninvasive,convenient,distinct and sensitive.Patients with PCOS showed sinificantly higher SA and SA/TA compared to those of the PCO group and control group.Conclusions In the case of detection of PCOS in virgin patients,transrectal three-dimensional ultrasonography combined with transabdominal ultrasonography can improve the precision of the diagnosis of PCOS.The SA/TA ratio might be considered as the ultrasound diagnostic parameter in PCOS.
