目的测量尿路膀胱尿道造影（VCUG）可测量的后尿道直径（PUD）和外尿道括约肌直径（EUSD），并利用视频尿动力学（VUDS）研究PUD/EUSD与排尿时逼尿肌压力（Pdet）的关系。方法选取63例3岁以下接受VUDS治疗的儿童为研究对象。我们测量了VUDS在排尿过程中EUS最宽时（pdet -排尿）的PUD和EUSD以及逼尿肌压力，并将PUD/EUSD与pdet排尿进行比较。结果63例患者共行78例VUDS，中位年龄10.2个月。这些研究显示PUD/EUSD与pdet排尿有显著相关性（r= 0.641,p< 0.001）。然而，PUD/EUSD与年龄之间没有显著相关性（r= 0.180）。我们将pdet -排尿大于80 cmH2O定义为高排尿压力，而PUD/EUSD为2.4是高排尿压力临界值的良好预测指标。在PUD/EUSD≥2.4的儿童中，pdet排尿明显增加（p< 0.001）。在19例患有神经系统疾病的儿童中，PUD/EUSD与pdet -排尿之间存在显著相关性（r= 0.842,p< 0.001），并且PUD/EUSD为2.4是高排尿压力的有用截止值。结论spud /EUSD是预测小儿高排尿压力的有效工具。VCUG中PUD/EUSD≥2.4表明需要对3岁及以下患有神经性疾病的儿童患者进行更多的侵入性检查，如VUDS。
PurposesWe measured posterior urethra diameter (PUD) and external urethral sphincter diameter (EUSD), which can also be measured by voiding cystourethrography (VCUG) and investigated the relationship between PUD/EUSD and detrusor pressure (Pdet) during voiding by videourodynamics (VUDS).MethodsSixty-three children, who were 3 years old or less and underwent VUDS, were enrolled in the present study. We measured PUD and EUSD in addition to detrusor pressure at the time of the widest EUS during voiding (Pdet-voiding) by VUDS, and PUD/EUSD was investigated compared to Pdet-voiding.ResultsSeventy-eight VUDS were performed in 63 patients, and the median age at VUDS was 10.2 months. These studies revealed a significant correlation between PUD/EUSD and Pdet-voiding (r= 0.641,p< 0.001). However, a significant correlation was not observed between PUD/EUSD and age (r= 0.180). We defined Pdet-voiding of more than 80 cmH2O as a high voiding pressure, and a PUD/EUSD of 2.4 was a good predictor for the cutoff value for high voiding pressure. Pdet-voiding was significantly higher in children with a PUD/EUSD of ≥ 2.4 (p< 0.001). In 19 children who had neurological diseases, a significant correlation was found between PUD/EUSD and Pdet-voiding (r= 0.842,p< 0.001), and a PUD/EUSD of 2.4 was a useful cutoff value for high voiding pressure.ConclusionsPUD/EUSD is a valuable tool to predict high voiding pressure in pediatric patients. A PUD/EUSD of ≥ 2.4 in VCUG indicates the need to perform more invasive tests, such as VUDS, in pediatric patients aged 3 and under with neuropathic diseases.
