Measurements of fundal height were obtained on 117 obstetric patients with a full and with an empty bladder. Statistical testing demonstrated a significant difference between the two measurements. A full urinary bladder can change fundal height measurements and thus be a source of false positive variations in the progression of fundal height. There is a need to establish a baseline (with the bladder empty) before measuring fundal height.
对117例产科患者在膀胱充盈和排空状态下进行了宫高测量。统计学检验表明这两种测量结果存在显著差异。膀胱充盈会改变宫高测量值，从而成为宫高进展中假阳性变化的一个来源。在测量宫高之前有必要确定一个基线（膀胱排空时）。
