目的：总结慢性前列腺炎患者可能存在的下尿路症状，并结合尿动力学分析各类症状出现的深层次原因。方法：对３２例慢性前列腺炎患者的尿流率、膀胱压力容积、压力－流率、前列腺压和肌电图进行综合性回顾分析，并与慢性细菌性和非细菌性前列腺炎组的尿动力学变化作了比较。结果：４０．６％的患者存在不稳定性膀胱，３４．４％的患者有逼尿肌反射亢进，４６．９％的患者有膀胱出口梗阻，另有６８．７％的患者存在逼尿肌－外括约肌协同失调。慢性细菌性和非细菌性前列腺炎组中的尿动力学差异无显著性意义．结论：慢性前列腺炎患者出现不同程度的尿频、尿急、尿等待和排尿费力等下尿路症状可能与前列腺局部充血、逼尿肌反射亢进、膀胱出口梗阻和逼尿肌－外括约肌协同失调有关。认识并解除这些相关因素可的有助于提高对慢性前列腺炎的综合疗效。
OBJECTIVE: To summarize the possible lower urinary tract symptoms in patients with chronic prostatitis and to analyze the underlying causes of various symptoms in combination with urodynamic study. Methods: A total of 32 chronic prostatitis patients with urinary flow rate, bladder pressure volume, pressure - flow rate, prostate pressure and electromyography were retrospectively analyzed, and with chronic bacterial and non-bacterial prostatitis group of urodynamic Learning changes have been compared. RESULTS: Unstable bladder was present in 40.6% of patients, detrusor hyperreflexia in 34.4%, bladder outlet obstruction in 46.9%, and detrusor in 68.7% of patients - Oesophageal sphincter disorders. There was no significant difference in urodynamics between chronic bacterial and nonbacterial prostatitis groups. Conclusions: The lower urinary tract symptoms such as urinary frequency, urinary urgency, urinary waiting and laborious urination in patients with chronic prostatitis may be related to prostatic congestion, detrusor hyperreflexia, bladder outlet obstruction and detrusor-external sphincter dysfunction . Understanding and relieving these related factors can help improve the comprehensive efficacy of chronic prostatitis.
