成人子宫、阴道应用解剖20例

APPLIED ANATOMY OF THE UTERUS AND VAGINA

为减少经阴宫切术并发症,对20具女尸子宫、阴道的解剖作了进一步观察。测量了子宫的长、宽、厚;见到子宫动脉在子宫侧缘外1.09±0.52cm 处从输尿管上方越过,在子宫峡部侧缘分2～8支;子宫前后腹膜返折的位置个体差异较大;子宫尿道隔紧密连接的高度为3.50±0.78cm(2.36～5.24),子宫直肠隔紧密连接的高度为1.54±0.93cm(0～3.50);输尿管在宫颈前唇上方0.59±0.61cm 处注入膀胱,距宫颈前壁仅0～0.55cm。以上观察结果在行经阴宫切术时是很有用的。

In order to reduce the complications in uterectomy through vagina the author observed the dissections of uteri and vaginae in the pelvic cavities of 20 female adult cadavers infused via blood vessels.The uterine length,width and thickness were measured.The uterine artery crossed over the ureter 1.09±0.52cm(0.4～2.2)beyond the uterine lateral margin and branched into 2～3 ramifications on the lateral margin and branched into 2～3 ramifica- ions on the lateral margin of uterine isthmus isthmus.There was a great difference among individuals in the position of peritoneal reflection on the anterior and posterior surfaces of the uterus.The urethrovaginal septa con- necting the urethrae with vaginae tightly were 3.5±0.78cm(2.36～5.24)in height,the tight connections of rectovaginal septa were 1.54±0.93cm(0～3.5) in height.The ureter entered the urinary bladder at the point 0.59±0.61cm above the anterior labrum of uterine cervix,only 0～0.55cm from the ante- trior wall of uterine cervix the results of these observations were useful in performing the uterectomy through vagina.
