目的探讨女性膀胱出口梗阻(Female Bladder Outlet Obstruction,FBOO)尿动力学诊断标准。方法对76例女性下尿路功能异常的患者进行尿动力学检查,通过检测最大自由尿流率(Qmax)、排尿期最大流率时逼尿肌收缩压(PdetQmax)结合排泄性膀胱尿道X线造影和膀胱尿道镜检作最终临床确诊。结果用Qmax<15ml/s,Pdet.Qmax>20cm H2O作诊断FBOO标准与用Qmax<12ml/s,Pdet.Qmax>20cm H2作诊断FBOO标准相比敏感性高,特异性稍低。结论FBOO是一种在临床诊断上并不多见的的疾病,内窥镜、影像学及尿动力学检查是明确诊断的主要方法,目前尚缺乏一种公认的FBOO尿动力学诊断标准。我们认为对于FBOO患者应该采用敏感性比较高的参数值(Qmax<15ml/s,Pdet.Qmax>20cmH2)。
Objective To investigate the urodynamic diagnostic criteria of Female Bladder Outlet Obstruction (FBOO). Methods Totally 76 patients with dysfunction of lower urinary tract underwent urodynamic examination. The maximum free flow rate (Qmax), the maximum detrusor discharge pressure (PdetQmax) and the excretion of bladder and urethra X-ray Radiography and bladder urethroscopy for the final clinical diagnosis. Results The diagnosis of FBOO using Qmax <15ml / s and Pdet.Qmax> 20cm H2O was more sensitive and slightly less specific than FBOO using Qmax <12ml / s and Pdet.Qmax> 20cm H2 for diagnosis. Conclusion FBOO is a rare disease in clinical diagnosis. Endoscopy, imaging and urodynamic examination are the main methods to confirm the diagnosis. Currently, there is a lack of a well-established diagnostic criteria for FBOO urodynamics. We think the more sensitive parameter values should be used for FBOO patients (Qmax <15ml / s, Pdet.Qmax> 20cmH2).
