Twenty-two patients with 24 fistulae were examined prospectively with real-time sonography. Sonographic findings were compared with those of intravenous urograms and correlated with the findings at examination under anesthesia and at surgery. Various genital abnormalities not revealed by intravenous urography were demonstrated by sonography preoperatively. These included cervical injuries, vesicovaginal fistula showing "flat tire" sign and hourglass deformities, and identification of the site, size, and course of fistulae in seven (29%) of the cases. However, the demonstration of the fistulae by sonography is poor relative to that of examination under anesthesia, in which 21 (87%) of the fistulae were identified. The factors responsible for the difficulty in demonstrating the fistulae on sonography, which included size and multiplicity, are discussed. Sonography is complementary to examination under anesthesia in preoperative evaluation of the patients with obstetric fistulae in general and in those with previous unsuccessful repairs in particular.
对22例患有24个瘘管的患者进行了实时超声检查。将超声检查结果与静脉尿路造影结果进行比较，并与麻醉检查和手术时的结果相关联。术前超声检查发现了静脉尿路造影未显示的各种生殖器异常。这些异常包括宫颈损伤、表现为“扁平轮胎”征和沙漏畸形的膀胱阴道瘘，以及7例（29%）病例中瘘管部位、大小和走行的确定。然而，相对于麻醉检查，超声检查对瘘管的显示较差，麻醉检查中识别出了21个（87%）瘘管。讨论了导致超声检查难以显示瘘管的因素，包括大小和多发性。一般而言，超声检查在产科瘘管患者的术前评估中，尤其是在既往修复失败的患者中，是对麻醉检查的补充。
