前列腺增生症致膀胱出口梗阻的尿动力学诊断

Urodynamics in evaluating bladder outlet obstruction in BPH

目的 :评价尿道阻力因子 (URA)、A G图、AG数在诊断前列腺增生症 (BPH)致膀胱出口梗阻(BOO)中的价值。方法 :分别应用URA、A G图和AG数对 69例BPH病人的压力 流率的检查结果进行分析。结果 :URA、A G图、AG数诊断BOO者分别为 73 .9%、62 .3 %和 68.1%。URA诊断为BOO ,而A G图诊断为可疑BOO者占 19.6%。URA和AG数呈显著正相关。结论 :URA、A G图、AG数对BOO的诊断均有意义。URA灵敏度较高。A G图可疑BOO者 。

Objective:To evaluate bladder outlet obstruction(BOO) in BPH using URA, A G nomogram and AG.Methods:Pressure flow studies were conducted in 69 cases of BPH. URA, A G nomogram and AG were used to analyse BOO respectively.Results:The detection rate of BOO on URA, A G nomogram and AG was 73.9%, 62.3% and 68.1% respectively. The rate of BOO detected on URA but equivocal on A G nomogram is 19.6%. There is notably close correlation between URA and AG.Conclusion:URA, A G nomogram and AG are all useful in detecting BOO. URA has a higher sensitivity. In case BOO is equivocal on A G nomogram, it should be further evaluated with URA.
