To determine what volume a child can normally store in the bladder at a safe pressure 923 pediatric urodynamic studies were reviewed, and 69 examinations done on 17 boys and 52 girls were considered normal. Patient ages were recorded and body surface areas were calculated. A continuous intermediate flow water cystometrogram had been performed. Total bladder capacity in milliliters, full resting pressures (cm. water), and the volumes (milliliters) and percentages of the total bladder capacity stored at detrusor pressures of less than 10, 20, 30 and 35 cm. water were measured. We found that 98.1% of the total bladder capacity could be stored at a detrusor pressure of less than 20 cm. water in more than 95% of the children independently of age or body surface area and 99.9% could be stored at a detrusor pressure of less than 30 cm. water. An approximation of the minimal acceptable total bladder capacity for age can be calculated by 16(age) + 70 in ml. According to our results, we proposed criteria for good storage characteristics of the bladder in children.
为了确定儿童在安全压力下膀胱的正常储尿量，我们回顾了923项小儿尿动力学研究，其中对17名男孩和52名女孩进行的69项检查被视为正常。记录了患者年龄并计算了体表面积。进行了连续中间流膀胱测压图检查。测量了以毫升为单位的膀胱总容量、完全静息压力（厘米水柱）以及在逼尿肌压力小于10、20、30和35厘米水柱时储存的容量（毫升）及其占膀胱总容量的百分比。我们发现，超过95%的儿童，无论年龄或体表面积如何，98.1%的膀胱总容量可在逼尿肌压力小于20厘米水柱时储存，99.9%可在逼尿肌压力小于30厘米水柱时储存。年龄的最小可接受膀胱总容量近似值可按16×（年龄）+70毫升计算。根据我们的结果，我们提出了儿童膀胱良好储尿特性的标准。
