[目的]探讨尿动力学检查在尿频患者病因中的诊断效果及临床应用价值.[方法]对 200 例尿频患者行尿动力学检查,根据检查结果给予对症治疗,观察患者的临床疗效,评价尿动力学检查在尿频病因诊断中的应用价值.[结果]经尿动力学检查发现,200例患者中膀胱出口梗塞80例(40.0%),其中52 例为尿道狭窄、28例为前列腺增生症,经行尿道扩张、经尿道前列腺电切术及药物治疗后,治疗有效率达到 92.5%(74/80).不稳定膀胱50例(25.0%),其中 32 例为慢性前列腺炎、18 例为间质性膀胱炎,经药物治疗后的总有效率为 92.0%(46/50).膀胱感觉过敏 30例(15.0%),均为逼尿肌反射亢进,经药物、心理干预及逼尿肌反射训练治疗总有效率为 86.7%(26/30).低顺应性膀胱 25 例(12.5%),经药物治疗后总有效率为 88.0%(22/25).逼尿肌无反射 15 例(7.5%),行膀胱造瘘、间歇性导尿、膀胱训练及对症药物干预后,有效率为 80.0%(12/15).[结论]尿动力学检查在确定尿频患者病因中具有较好的应用效果,可为选择正确治疗方法提供参考,值得在临床中推广使用.“,”[Objective]To investigate the diagnostic value and clinical value of urodynamic examination in the etiology of urinary frequency patients.[Methods]A total of 200 patients with urinary frequency were selected as subjects.All patients underwent urodynamic examination.According to the results of the examination,symptom-atic treatment was given.The clinical efficacy of the patients was observed.The value of urodynamic examination in the diagnosis of urinary frequency etiology was evaluated.[Results]Among the 200 patients,80 cases (40.0%) were found to be bladder outlet obstruction by urodynamic examination,including 52 cases of urethral strictures and 28 cases of pre-existing prostate hyperplasia.The patients underwent urethral dilatation,transurethral resec-tion of prostate and received medication.After treatment,the effective rate of treatment was 92.5%(74/80). There were 50 cases of unstable bladder (25.0%),of which 32 cases were chronic prostatitis and 18 cases were in-terstitial cystitis.The total effective rate after drug treatment was 92.0%(46/50).Thirty cases (15.0%)of blad-der hypersensitivity were detrusor hyperreflexia.The total effective rate was 86.7%(26/30)after drug treatment, psychological intervention and detrusor reflex training.Low compliance bladder was found in 25 (12.5%)patients and the total effective rate was 88.0%(22/25)after drug treatment.Detrusor muscle without reflex in 15 cases (7.5%),and the effective rate after bladder spasm,intermittent catheterization,bladder training and intervention of symptomatic drugs,the effective rate was 80.0%(12/15).[Conclusion]Urodynamic test has beneficial applica-tion in determining the etiology of urinary frequency patients.It can provide a reference for selecting the correct treatment method and is worthy of promotion in clinical practice.
