Iatrogenic Ureteral Obstruction During Transvaginal Oocyte Retrieval

ABSTRACT Transvaginal oocyte retrieval is a crucial step in assisted reproductive technology. Various complications may arise during this procedure. Ureteral injury is a rare, but a serious complication in gynecological practice. During oocyte retrieval, ureteral injuries, detachment and obstruction can be seen, though rare. In this study, we will present ureteral obstruction that develops secondary to small hematoma, which mimics ovarian cyst torsion or ruptured ovarian cyst.摘要 经阴道取卵术（Transvaginal oocyte retrieval）是辅助生殖技术（assisted reproductive technology）中的关键环节。该操作期间可发生多种并发症。输尿管损伤（ureteral injury）是妇科临床实践中一类少见却严重的并发症。尽管此类情况少见，但在经阴道取卵术中仍可观察到输尿管损伤、输尿管离断及输尿管梗阻等病变。本研究将报告一例由小型血肿继发所致的输尿管梗阻病例，该病症的临床表现易与卵巢囊肿蒂扭转（ovarian cyst torsion）或卵巢囊肿破裂（ruptured ovarian cyst）相混淆。
