摘要
目的:以脊髓脊膜膨出的婴儿为研究对象,进行术前尿动力学检查,评估其膀胱功能。方法2010年2月至2014年3月,本院收治脊髓脊膜膨出患儿25例,年龄45d至1个月,平均4个月,术前应用加拿大莱博瑞(Laborie)尿动力检查系统,慢速灌注充盈膀胱进行膀胱测压。结果术前尿动力检查结果:尿动力表现完全正常13例(52%);膀胱活动活跃6例(24%);间断排尿4例(16%);逼尿肌不稳定2例,其中1例膀胱顺应性3 mL/cmH2 O。所有患儿膀胱容量正常,(48.3±19.8)mL。残余尿均未见明显增加,平均(3.2±4.5)mL。因膀胱活动活跃、间断排尿多见于正常婴儿,本组23例被认为尿动力结果正常,占92%。所有患儿均经手术确定脊髓脊膜膨出及脊髓栓系诊断,其中脂肪脊髓脊膜膨出15例(占60%)。结论尿动力学检查提示术前脊髓脊膜膨出的婴儿,其膀胱功能多为正常,其神经源性膀胱的损害在1岁以内多未表现出来。
Objetive To evaluate the myelomeningocele infants ’ bladder functions with urodynamic study before operation. Methods From February 201 0 to April 201 4,a total of 25 infants with myelomeningo-cele were included in this study with age from 2 months to 1 1 months old and a mean 4.0 months.Slow-fill cys-tometry examination was performed with Laborie urodynamic system before surgery. Results Urodynamic of 1 3 patients (52%)were completely normal.Hyperactivity of detrusor was found in 6 patients (24%).Interrupt-ed voiding was found in 4 cases (1 6%).2 patients have instable detrusor,among them 1 patient’s bladder compliance is 3 ml/cmH2 O.No obvious increase of residual urine was found in all cases and the mean is 3.2 ±4.5 ml.Because hyperactivity and interrupted voiding are thought to be normal in infants,23 patients (92%)are considered with normal urodynamic results.The diagnosis of myelomeningocele and tethered cord syndrome was confirmed after surgery.Among them,1 5 cases (60%)were diangnosed as lipomyelomeningo-cele post-operation. Conclusion Infants with myelomeningocele have normal bladder function in their first year pre-operation.
