摘　　要：目的探讨前列腺增生(BPH)患者尿道内置F8测压管在压力-流率测定中对尿流率的影响。方法对54例良性BPH患者行压力-流率测定,尿道内放置F8测压导管,比较尿流率和置管后尿流率的变化。结果 54例患者置管前后最大尿流率、平均尿流率比较,经t检验,差异有统计学意义(P<0.05)。置管前后尿流量比较,经t检验,差异无统计学意义(P>0.05)。膀胱出口梗阻Ⅱ~Ⅳ级患者的最大尿流率与最大置管尿流率比较,差异有统计学意义(P<0.05),0、Ⅰ级和Ⅴ、Ⅵ级的最大尿流率、最大置管尿流率比较,差异无统计学意义(P>0.05)。结论 BPH患者尿道内置F8测压导管影响尿流率测定值。Objective To study the impact of intra-urethral catheter on uroflow rate in pressure-flow study.Methods Fifty-four men with benign prostate hyperplasia(BPH)underwent free uroflometry and pressureflow analysis respectively.With an F8urethral catheter,the standard pressure-flow variables such as the maximum flow and catheter’s uroflow rate were measured and analyzed with paired t test.Results The maximum free uroflow rate and the mean free uroflow rate were significantly different before and after catheterization(P<0.05).The maximum voided volume in free uroflometry and in pressure-flow study was not statistically different(P>0.05).There were significant differences in the maximum uroflow rate and the maximum catheter’s uroflow rate among the patients with bladder outlet obstruction of grade II-IV(P<0.05),but there were no significant differences among the patients with bladder outlet obstruction of grade0,I,V and VI(P>0.05).Conclusions F8urethral catheter appears to have significant impact on uroflow rate.
