慢性前列腺炎患者的尿动力学检查（附32例报告）

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例民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％，的患者有逼尿肌反邮进，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能有助于提高对慢性前列腺炎的综合疗效。

The urodynamics study in patient with chronic prostatitis (Report of 32 cases)

Purpose:To evaluate the dysfunction of the low urinary tract of patient with chronic prostatitis(CP) by analyzing urodynamic profile. Methods:Our retrospective study was based on 32 patients with CP in urology clinics. The clnical data included the measurement of maximum uroflow rate(Qmax).prostatic pressure, filling cystometry,pressure-flow(P/Q)study of voiding and electromyography of the external urethral sphincter. Results: 13 patients(40. 6%)had unstable bladder, 11(34. 4% )had detrusor hyperreflex, 15(46. 9%)had bladder outflow obstruction and 22(68. 7%)had detrusor-sphincter coordinated disturbances. The urodynamic difference between chronic bacterial prostatitis(CBP) and chronic nonbacterial prostatitis(CNBP) wasn't statistically significant. Conclusions:The low urethral tract symptoms e. g urgency,frequency and dysuria may be associated with unstable bladder, bladder outflow obstruction, detrusor hyperreflex and detrusor-sphincter coordinated disturbances induced by prostatic hyperemia, pelvic pain or muscle spasm and alpha-receptor excitement. We believe that recognizing and eliminating these relative factors will be helpful to increase synthetic therapeutic effects on CP.
