The present study investigated the effect of bladder distension on in vitro fertilization and embryo transfer (IVF-ET) results.
The study comprised 796 patients after successful transvaginal oocyte pickup and IVF, who, on the basis of bladder filling for ET, were divided into two groups. In group E, 385 patients underwent ET with an empty bladder, and in group F, 411 patients underwent ET with a full bladder.
Sixty-four pregnancies were achieved in group E (16.6%), compared to 110 pregnancies in group F (26.8%, P = 0.006). A similar pregnancy loss rate was observed in both groups, 13 in group E (20.3%) and 29 in group F (26.4%; P = NS).
A significantly higher pregnancy rate was achieved with routine bladder distension before ET, probably attributable to the smooth and easy insertion of the ET catheter.
本研究调查了膀胱充盈对体外受精-胚胎移植（IVF-ET）结果的影响。
该研究纳入了796例经阴道取卵和IVF成功后的患者，根据胚胎移植时膀胱的充盈情况将其分为两组。E组385例患者在膀胱空虚状态下进行胚胎移植，F组411例患者在膀胱充盈状态下进行胚胎移植。
E组有64例妊娠成功（16.6%），而F组有110例妊娠成功（26.8%，P = 0.006）。两组观察到相似的妊娠丢失率，E组13例（20.3%），F组29例（26.4%；P = 无显著性差异）。
胚胎移植前常规膀胱充盈可显著提高妊娠率，这可能归因于胚胎移植导管插入顺利且容易。
