The emergence of transvaginal ultrasound-guided oocyte retrieval provided an opportunity to review and improve the traditional transabdominal ultrasonic approach for follicular tracking in in vitro fertilisation (IVF). This technique requires a full bladder, which may cause extreme discomfort. Hence, to provide both effective and comfortable monitoring, we instituted a study comparing transabdominal and transvaginal ultrasonography, with regard to patient preference and follicular number, size and dominance, in patients undergoing IVF and gamete intrafallopian transfer (GIFT). Commencing usually on day 9 of the treatment cycle, 45 patients were scanned on 55 occasions, initially abdominally (with a full bladder) and subsequently vaginally, using a transvaginal 7.5 MHz sector transducer. Follicular number was identical in 78% of cases, with the majority of the remaining patients showing an extra follicle on vaginal assessment. There were no significant differences in overall or dominant follicular diameters with either technique. Overall, 85% unashamedly preferred the vaginal approach. We believe that tracking follicular development in IVF treatment cycles is efficient and popular using the vaginal sector transducer and accordingly have ceased all assessments using the abdominal probe. Subsequently, 450 follicle scans have been performed with virtually the unanimous approval of our patients.
经阴道超声引导下取卵技术的出现，为回顾和改进体外受精（IVF）中卵泡监测的传统经腹超声方法提供了契机。这项技术需要膀胱充盈，这可能会导致极度不适。因此，为了提供有效且舒适的监测，我们开展了一项研究，比较接受IVF和配子输卵管内移植（GIFT）的患者在经腹超声和经阴道超声检查方面的差异，包括患者偏好以及卵泡数量、大小和优势情况。通常从治疗周期的第9天开始，对45例患者进行了55次扫描，最初是经腹扫描（膀胱充盈），随后使用经阴道7.5 MHz扇形探头进行经阴道扫描。78%的病例中卵泡数量相同，其余大多数患者经阴道评估时发现有额外的卵泡。两种技术在总体卵泡直径或优势卵泡直径方面均无显著差异。总体而言，85%的患者毫不掩饰地更喜欢经阴道检查方法。我们认为，使用阴道扇形探头在IVF治疗周期中监测卵泡发育是高效且受欢迎的，因此我们已停止使用腹部探头进行所有评估。随后，我们进行了450次卵泡扫描，几乎得到了所有患者的一致认可。
