超声输卵管显影技术的研究

Study on the Techniques of salpingosonography

目的：探讨输卵管及盆腔粘连的超声显像方法。方法：经宫腔向盆腔通水或经阴道穹窿穿刺向盆腔注水使盆腔积液后用阴道超声作盆腔扫描。结果：向盆腔注入一定量的液体能使输卵管伞端及盆腔粘连带在阴道B超上显影。对69例超声输卵管显影进行分析发现，输卵管伞端显影率随盆腔积液量增加而提高，积液600ml以上显影率最高。穿刺注水法的注水量显著高于经宫腔通液法的注水量（790．9±383．3ml比308．6±172．0ml，P＜0．0001），前者输卵管伞端显影率较后者高（86．3％比62．6％）。结论：超声输卵管显影术能清楚地显示输卵管伞端的形态，活动度，通畅度及盆腔粘连。为获得更好的显影效果，盆腔注水量应超过600ml。穿刺注水法输卵管伞显影效果更好。

Objective: To develope a method for imaging the frmbria of fallopian tubes and pelvic adhesions with trans vaginal ultrasonography (TSU). Methods: scanning the pelvic with TVC after saline fillin, by two methods. first is intrauterne hydrotubation,second by puncturing through fornix of vagina under the guide of TVU. Results: When sufficient amount of fluid accumulated in pelvis the fimbria of fallopian tubes and pelvis adhesions could be imagied by TVU clearly. 69 cases were studied, and the results showed that the rate of fimbria increased in proportion with pelvic fluid in crement . when the volume over 600 ml. The fluid volume perfused into pelvic by method second was significantly larger than that by method first (790. 9 ±383. 3 ml vs 308. 6 ± 172. higher in former than in later (86. 3 % vs 62. 6 % ). Conclusions: Salpingosonography could cleary show the form, motility, patency of fimbria and pelvic adhesions. To get better imaging results, over 600 ml fluid must ha perfused into pelvic, easily achieved by method two.
