摘 要：目的：探讨慢性前列腺炎可能存在的下尿路症状，结合尿动力学检查分析其原因。方法：采用丹迪尿流测定仪对20例慢性前列腺炎患者进行尿流率、充盈性膀胱侧压、压力—流率测定、尿道侧压及肌电图检查。结果：不稳定性膀胱9例(45%)，低顺应性膀胱5例(25%)，膀胱出口梗阻11例(55%)，逼尿肌尿道括约肌协同失调7例(35%)，其中不稳定膀胱合并膀胱出口梗阻6例，低顺应性膀胱合并膀胱出口梗阻4例，不稳定膀胱合并逼尿肌尿道外括约肌协同失调2例。结论：慢性前列腺炎患者的下尿路症状与不稳定性膀胱、低顺应性膀胱、膀胱出口梗阻及逼尿肌尿道外括约肌协同失调有关，了解这些相关因素对治疗有重要的指导意义。

    Abstract: Objective：The aim of the study was to explore the possible symptom of inferior urinary tract in patients with chronic prostatitis urodynamic. Methods：20 patients with chronic prostatitis urodynamic were measured the urine flow rate , engorged bladder lateral pressure, pressure - flow rate , lateral pressure of urinary tract by using the DANDI urodynamic radiomete and underwent electromyogram examination . Result: Unstable bladder in 9 cases(45%), low compliance bladder in 5 cases (25%) , obstruction in the bladder outlet in 11 cases (55%), dyssynergia in detrusor muscle and external urethral sphincter in 7 cases (35%), unstable bladder with obstruction in the bladder outlet in 6 cases, low compliance bladder with obstruction in the bladder outlet in 4 cases , unstable bladder with dyssynergia in detrusor muscle and external urethral sphincter in 2 cases .Conclusion : The symptom of inferior urinary tract in patients with chronic prostatitis urodynamic was related to the unstable bladder, low compliance bladder , obstruction in the bladder outlet and dyssynergia in detrusor muscle and external urethral sphincter ,to know the correlation factors do significant benefit in guiding the clinical treatment. ......
