文摘纵隔子宫(septate uterus)是最常见的女性生殖器畸形,但是临床医生常常被有关其诊断和治疗的一些问题所困惑。比如:纵隔子宫诊断的金标准是什么?纵隔子宫的宫底外形可能是不正常的吗?纵隔子宫的手术指征(特别是很浅的纵隔是否需要手术)?经宫颈子宫纵隔切除术(transcervical resection of septum,TCRS)术中采用何种监护方式最好?切除子宫纵隔时采用针状电极还是环状电极?TCRS术中何时可以认为纵隔已经完全切除了?TCRS术中发现子宫左右侧壁明显凸向宫腔是否需要同时矫形?TCRS术后是否需要放置宫内节育器或者用雌激素促进子宫内膜生长?TCRS术后为什么容易出现阴道出血量较多的现象?等等。这些问题直接影响了临床医生的临床决策,也造成了妇科和生殖科医生的认识混乱。针对纵隔子宫诊断和治疗相关的临床问题进行解析,以期进一步指导临床实践。
