经直肠三维超声诊断未婚青少年多囊卵巢综合征的应用

目的 探讨经直肠三维超声诊断未婚青少年多囊卵巢综合征（PCOS）的价值。方法 采用经直肠三维超声对45例PCOS患者、30例单纯卵巢多囊性改变（PCO）患者和25例正常者进行观察，分别测量其卵泡数、卵巢体积、卵巢总面积（TA）、髓质面积（SA）和髓质面积与卵巢总面积的比值（SA／TA）。结果 经直肠三维超声对未婚青少年卵巢细致结构的显示优于经腹超声，且无创、方便、清晰、敏感。PCOS患者SA、SA／TA明显高于PCO及正常对照组，差异有统计学意义（P〈0．05或P〈0．01）。结论 经直肠三维超声提高了对未婚青少年PCOS的诊断水平，与经腹超声联合应用能提高诊断准确性，减少漏诊率。SA／TA可作为辅助诊断PCOS的指标。

Value of transrectal three-dimensional ultrasound in diagnosis of polycystic ovarian syndrome in virgin patients

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.
