Abstract:

Objective　To explore morphologic features of the fallopian tube of reproductive aged women and provide the basis for the study of tubal sterilization and fertility.　Methods　The length, diameter and the orifice of the fallopian tube were observed, measured and analyzed on the data from 100 cases of salpingography (HSG), 30 cases of hysteroscopy and 20 cadaveric specimens.　Results　HSG showed that, the diameter of internal orifice，the lengths of the middle and distal of interstitial parts were about （1.07±0.48） mm, （0.50±0.22） mmand （0.32±0.12） mm averagely, respectively. The internal diameter of the isthmus and the ampulla were (0.46±0.28 mm) and (2.43±1.45) mm respectively. the length of interstitial part, isthmus, ampulla and the total were (5.27±4.28 mm), (24.35±12.27) mm，(39.94±22.05)mm and (70.78±32.07) mm respectively. Hysteroscopy showed the round(76.7%) or oval（23.3%）internal orifices of fallopian tube. The perimeter of internal orifice was (5.87±1.46)mm, and of the isthmus (2.83±1.87) mm. The length of interstitial part, isthmus and the total were (6.73±2.49) mm, (20.56±7.61) mm and (85.42±22.93) mm, respectively on cadaveric specimens.    Conclusions    Fallopian tube is a tortuous channel with the dilated internal and external orifices. The interstitial part is funnel-shaped, with the narrowest part at the distal of it. It is necessary to understand morphologic features of fallopian tube for the study of sterilization and fertility.
