1500例遗尿症的功能性膀胱容量分析

Functional bladder capacity in 1500 children with nocturnal enuresis

目的分析了解遗尿症患儿的功能性膀胱容量（FBC）及其与尿床次数的相关性，为遗尿症的治疗提供临床依据。方法对1500例遗尿症患儿进行问卷调查及泌尿系B超检查，尤其是功能性膀胱容量的测定。结果①男：女=1．3：1，5—10岁：1305例（87％）；10～14岁：181例（12％）；15～18岁：14例（1％）。②FBC≤正常值的50％（即FBC减少）的尿床患儿共637例（42．4％）。③1500例患儿中，按尿床程度分为4组：尿床／〉2次／每晚的患儿53例（3．5％）；尿床次数〉／7次／周的患儿969例（64．6％）；尿床3～6次／周的患儿380例（25．3％）；尿床1～2次／周的患儿98例（6．5％）；其FBC减少的发生率分别是79．2％，48．3％，29．7％和14．3％，组间比较差异有显著性。结论在深圳地区就诊的遗尿患儿大多数为每天尿床的重型遗尿症，其中近一半的患儿存在着功能性膀胱容量减少，并且与尿床的程度具有高度的相关性，尿床次数越频繁，FBC减少的比例越高。

Objective To study the association of functional bladder capacity with the severity of bedwetting in children with nocturnal enuresis. Methods A questionnaire investigation was performed in 1 500 children with nocturnal enuresis and the functional bladder capacity was examined by B-ultrasound. Restdts The ratio of males to females was 1.3： 1. The majority of patients （87%）were in an age range of 5-10 years, followed by the 10-14 years group （12%）, and the 15-18 years group （1%）. Six hundred and thirty-seven patients （42.4%） showed a decreased functional bladder capacity （less than 50% of normal level）. The patients were classified into four groups according to the severity of bedwetting （ from severe to mild） ： 〉/2 times per night （ n = 53, 3.5% ）, 〉/7 times per week （ n = 969, 64.6% ）, 3-6 times per week （ n = 380, 25.3% ） and 1-2 times per week （ n = 98, 6.5% ）. The incidence of the reduction in functional bladder capacity in the above four groups was 79. 2%, 48.3%, 29.7% and 14. 3% respectively and a significant difference was noted among the four groups. Conclusions Most of children with nocturnal enuresis showed decreased functional bladder capacity. Functional bladder capacity is associated with the severity of bedwetting in children with nocturnal enuresis.
