前列腺增生症尿动力学检查的临床研究

目的 评价尿动力学检查(UDS)在良性前列腺增生症(BPH)诊治中的意义。方法 对102例BPH病人进行详细尿动力学检查,包括尿流率、充盈期膀胱测压、压力-流率测定、残余尿测定,应用P-Q图进行分析是否存在膀胱出口梗阻。术后随访,行残余尿、尿流率测定。结果 尿流率Qmax<15ml/s 98例;低顺应性膀胱17例,高顺应性膀胱22例,顺应性正常63例;通尿肌不稳定42例;通尿肌收缩力正常或增强84例,减弱18例;压力-流率测定P-Q图示膀胱出口梗阻84例;残余尿<100ml 50例,>100 ml 52例。术后随访80例症状消失,排尿顺畅。结论 尿流动力学检查能明确BPH有无膀胱出口梗阻、逼尿肌的顺应性和收缩功能,对术前合理选择病人和提高手术疗效有重要意义。

The urodynamic studies in patients with benign prostatic hyperplasia

Objective To evaluate the significance of Urodynamic studies (UDS) in the diagnosis and treatment of benign prostatic hyperplasia (BPH). Methods The UDS was performed in 102 patients with BPH, which included Uroflowmetry (UFR), Filling cystometry (CMG), pressure flow study, measurement of residual urine, analysis of bladder outlet obstruction (BOO). The patients were followed - up and were performed measurement of residual urine and UFR after operation. Results It was found that 98 patients had Qmax <15ml/s. The vesical compliance was low in 17 patients, high in 22 patients and normai in 63 patients. 42 patients had detrusor urinae instability (DI) . The detrusor urinae constractility was normai and increased in 84 patients and low in 18 patients. The 84 cases were showed BOO with P - Q diagram. the residual urine <100ml was found in 50 patients and >100ml in 52 cases. The smooth urination and symptomatic disappearance were found in 80 cases after operation. Conclusion The Urodynamic studies can be determined the presence and degress of BOO, the vesical compliance and detrusor urinae contractility function, and would play an important role in selecting patients for prostatectomy.
