In a trial of labour after caesarean section, X-ray pelvimetry has generally been regarded as an important part in the evaluation of patients before a decision is made. A review of 445 patients with trial of labour has shown that although the measurements of the pelvic inlet were greater in patients who delivered vaginally, the incidence of successful trial was not related to the measurements of the pelvis. Maternal height was also unrelated to the outcome. Only a history of previous vaginal delivery was predictive of a successful trial. The results suggest that X-ray pelvimetry is not necessary in the majority of patients if the past obstetric history and the clinical assessment are in favour of a successful trial. It is only useful when there is doubt and in this case both a lateral and an antero-posterior film are necessary as the obstetric conjugate alone was unreliable in predicting the transverse diameter of the inlet as well as the outcome.
在剖宫产术后试产中，在做出决定前，X线骨盆测量通常被视为评估患者的重要部分。对445例试产患者的回顾显示，尽管经阴道分娩患者的骨盆入口测量值更大，但试产成功的发生率与骨盆测量值无关。产妇身高也与分娩结局无关。只有既往阴道分娩史可预测试产成功。结果表明，如果既往产科病史和临床评估有利于试产成功，大多数患者无需进行X线骨盆测量。只有在存在疑问时它才有用，在这种情况下，侧位片和前后位片都有必要，因为仅产科结合径在预测入口横径以及分娩结局方面并不可靠。
