非压力-流率参数对良性前列腺梗阻的诊断价值

The diagnostic value of none pressure-flow parameters in benign prostatic obstruction

目的探讨压力-流率检查(PFS)中无排尿良性前列腺梗阻(BPO)病人的梗阻判定方法。方法对选定的非压力-流率参数在梗阻和非梗阻组间进行比较,并分析其对梗阻的诊断价值。结果351例有完整和可供分析PFS资料的良性前列腺增生(BPH)患者中,明确膀胱出口梗阻(BOO)者221例,非BOO者130例。BOO组和非BOO组比较,逼尿肌不稳定(DI)发生率分别为51.13％和31.54％(P<0.05);逼尿肌开放压(Pdet.open)分别为(89.74±34.27)cmH2O和(42.05±25.85)cmH2O(P<0.05)。逼尿肌开放压大于60 cmH2O时BOO发生率高达91.5％。DI患者有113例(73.38％)存在BOO。结论 PFS时无排尿病人的膀胱出口梗阻可以借助其最大逼尿肌压以及是否存在逼尿肌不稳定进行判断。

Objective To approach the diagnostic value of urodynamic data from pressure-flow study (PFS) in benign prostatic obstruction (BPO) patients. Methods To select a few none pressure-flow parameters and compare them between bladder outflow obstruction (BOO) and none BOO groups in order to evaluate their diagnostic significance. Results A total of 351 patients received PFS were available for study. 221 patients were having BOO and the rest 130 having no BOO. The incidence of detrusor instability (DI) was 51. 13% in BOO group and and 31. 54% in none BOO group,respectively(P <0. 05) ;the opening pressure(Pdet. open) was (89. 74 ±34. 27)cmH2O and (42.05 ±25. 85 )cmH2O,respectively(P < 0, 05) . The incidence of BOO was as high as 91. 5% when Pdet. open was over 60 cmH2O. 113 cases (73. 38% ) of the patients with DI were suffering from BOO, Conclusions The maximum detrusor pressure and DI could be used as reference parameters for bladder outflow obstruction in dealing with BOO in BPH patients.
