　　目的探讨前列腺增生合并慢性前列腺炎患者膀胱功能的尿动力学特点。方法选取2009年6月至2012年6月在解放军第309医院住院的前列腺增生患者187例。按是否合并前列腺炎分为单纯前列腺增生组（n＝91）及合并前列腺炎组（n＝96）。比较两组尿动力学检查指标，包括膀胱容量、最大逼尿肌压力、膀胱稳定性及最大尿道闭合压的差异。结果两组患者测得的膀胱容量（P＝0.741）、最大逼尿肌压（P＝0.872）、最大尿道闭合压（P＝0.590）比较差异无统计学意义；单纯前列腺增生患者的膀胱稳定性优于前列腺增生合并慢性前列腺炎患者，两组间比较差异具有统计学意义[（158.0±42.7） vs （79.6±30.0）ml，P＝0.032]。结论前列腺增生合并慢性前列腺炎患者尿动力学表现主要以不稳定性膀胱为主，导致患者出现尿频、尿急、尿道不适感。

Objective To investigate the urodynamics of bladder function in patients suffering from benign prostate hyperplasia (BPH) and prostatitis. Methods One hundred and eighty-seven inpatients with BPH hospitalized in our department from June 2009 to June 2012 were recruited in this study. They were assigned to two groups according to being accompanied with prostatitis or not, that is, BPH group (n=91) and BPH combined with chronic prostatitis (CP) group (BPH/CP group, n=96). Urodynamic indices, such as maximum bladder capacity, maximum detrusor pressure, bladder stability and maximal urethral closure pressure were measured and then compared between the two groups. Results There was no significant difference in the urodynamic parameters, including maximum bladder capacity (P=0.741), maximum detrusor pressure (P=0.872) and maximal urethral closure pressure (P=0.590) between the two groups. But, simple BPH patients had better bladder stability than the BPH/CP group [(158.0±42.7) vs (79.6±30.0)ml, P=0.032]. Conclusion BPH combined with CP mainly manifests bladder instability urodynamically, which further leads to urinary frequency, urgency and discomfortableness.
