We evaluated 4-hour voiding observation as a method of basic assessment of bladder dysfunction in young boys with posterior urethral valves.
Voiding pattern, including number of voids, voided and residual urine volume, and bladder capacity, was determined noninvasively in 24 boys younger than 4 years with posterior urethral valves and compared to that of healthy age matched controls. Results were then compared to those of standard cystometry.
The number of voids was higher, voided volume was smaller and residual urine volume was higher in the posterior urethral valve group. There was no difference in voiding pattern before and after removal of the anatomical obstruction. Voided and residual urine volume, and bladder capacity were higher on standard cystometry than on voiding observation.
Four-hour voiding observation is an easy noninvasive method that focuses on emptying difficulties and clearly detects differences in voiding patterns between boys with posterior urethral valves and healthy, nontoilet trained children. We recommend the method as a complement to standard cystometry for the diagnosis and followup of bladder dysfunction in young boys with posterior urethral valves to identify the need for treatment.
我们评估了4小时排尿观察作为后尿道瓣膜症男童膀胱功能障碍基本评估方法的效果。
对24名4岁以下患有后尿道瓣膜症的男童进行无创测定排尿模式，包括排尿次数、排尿量和残余尿量以及膀胱容量，并与年龄匹配的健康对照儿童进行比较。然后将结果与标准膀胱测压法的结果进行比较。
后尿道瓣膜症组的排尿次数更多，排尿量更小，残余尿量更高。解除解剖学梗阻前后的排尿模式没有差异。标准膀胱测压法测得的排尿量和残余尿量以及膀胱容量高于排尿观察法。
4小时排尿观察是一种简单的无创方法，重点关注排尿困难，并能清晰检测出患有后尿道瓣膜症的男童与健康、未接受如厕训练儿童之间排尿模式的差异。我们建议将该方法作为标准膀胱测压法的补充，用于诊断和随访患有后尿道瓣膜症的男童膀胱功能障碍，以确定是否需要治疗。
