摘要目的 比较女性排尿困难患者的尿动力学诊断分型在不同年龄组的差别.方法 1997年3月至2008年7月,门诊以排尿困难为主诉的女性患者616例,无神经系统病史和下尿路手术史,行膀胱压力-流率测定及自由尿流率检查,按3个年龄组统计诊断分型.结果 在>18且≤40岁、>40且≤60岁及60岁以上3个年龄组中,膀胱出口梗阻的比例均较高,分别为54.8% 、59.1% 和45.0% .逼尿肌过度活动、逼尿肌肌力弱、正常三项尿动力学检查结果 在3组间无显著性差异,而膀胱出口梗阻、逼尿肌无反射两项分布有显著性差异.将>18且≤加岁组与>40且≤60岁组合并形成的中青年组与60岁以上的老年组比较,膀胱出口梗阻、逼尿肌无反射、逼尿肌肌力弱三项有显著性差异,膀胱出口梗阻在两组的比例为57.3% 和45.0% ,逼尿肌无反射在两组的比例为15.6% 和23.9% ,逼尿肌肌力弱在两组的比例为17.4% 和25.0% .在逼尿肌肌力弱患者中,存在膀胱感觉减退的比例在老年组中明显升高.结论 女性排尿困难患者的尿动力学诊断中,膀胱出121梗阻的比例最高,其比例在老年患者中有所下降,而逼尿肌无反射和逼尿肌肌力弱的比例在老年患者中增高.

abstractsObjective To compare the urodynamic diagnostic types of dysuria in female patients of different age groups.Methods Six hundred and sixteen female patients with dysuria were evaluated from March 1997 to July 2008.No patients had history of nervous system disease and history of lower urinary tract operations.They had detruser pressure-flow studies and uroflowmetry.The urodynamic diagnostic types were analyzed in 3 different age groups.Results In 3 groups of 18-40 years, 40-60 years and ≥60 years, the diagnosis of bladder outlet obstruction (BOO) had the highest proportion (54.8% , 59.1% and 45.0% respectively).The distribution of detrasor overaetivity, detrasor underactivity and normal ftmetion had no significant differenee between 3 groups.The distribution of BOO and aeontraetile detrusor had significantly difference between 3 groups.When groups of 18-40 years and 40-60 years were combined into 18-60 years group and compared with the older group, the proportion of BOO, aeontraetile detmsor and detrusor underaetivity showed significantly differenee.The proportions of BOO in the two groups were 57.3% and 45.0% , aeontraetile detrusor 15.6% and 23.9% , detrnsor underaetivity 17.4% and 25.0% , respectively.The proportion of reduced bladder sensation among detrusor underaetivity patients in the older group was significantly higher.Conclusions In the uradynamie diagnoses of voiding difficulty in female patients,bladder outlet obstruction has the highest proportion.This proportion decreases in the older patients.The proportion of aeontraetile detrusor and detrusor underaetivity increases in the older group.
