摘　　要：目的:探讨剩余分数(RF)在评价BPH致膀胱出口梗阻(BOO)程度及逼尿肌功能的应用价值。方法:69例BPH患者行尿动力学各项指标测定,分析剩余尿量(PVR)和RF与排尿前尿量、Qmax、逼尿肌收缩强度的相关性。结果:PVR与排尿前尿量呈显著正相关(r=0.6154,P<0.01),RF与排尿前尿量则无明显相关性(r=0.2419,P=0.07)。PVR与Qmax呈显著负相关(r=-0.3212,P<0.01),RF与Qmax呈极显著负相关(r=-0.4356,P<0.01)。逼尿肌收缩强度为极弱、弱与正常和强的患者的PVR、RF的差异均有统计学意义(分别为P=0.0172,P=0.0021)。结论:RF不受排尿前尿量的影响,是一项较PVR能更好的评价BPH所致BOO及其程度和逼尿肌收缩功能的静态指标。Objective：To explore the value of residual fraction（RF） in the evaluation of the degree of bladder outlet obstruction（BOO） and detrusor contractility resulting from benign prostatic hyperplasia（BPH）. Methods：69 cases with BPH were evaluated and the correlations between postvoid residual volume（PVR）.RF and prevoid volume、Qmax、 detrusor contractility were determined. Results：The cofficient between PVR and prevoid volume showed extremely positive correlation （ r = 0. 6154, P 〈0.01 ）. While RF had no correlation with prevoid volume（ r = 0. 2419, P =0.07）. Also the cofficient between PVR and Q showed negative correlation （ r = -0. 3212, P 0, 01 ）and between RF and Qmax showed extremely negative correlation（r=-0. 4356, P d0.01 ）. Significant differences of the PVR and RF were shown between the patients whose detrusor contractilities were VW or W and the patients N or ST（ the former P = 0.0172, the latter P = 0. 0021 ）. Conclusions ： RF is not influenced by prevoid vol ume and is a better static index than PVR in evaluating the degree of BOO caused by BPH and detrusor contractility.
