男性静止期尿道压力测定中测压灌注速度与测压管牵引速度较优组合的研究

Optimum Combination of Manometric Perfusion Speed and Manometric Tube Traction Speed in Male Resting Urethral Pressure Measurement

目的探讨在静止期尿道压力测定中测压灌注速度、测压管牵引速度2个参数的较优组合。方法对30例前列腺增生症患者采用尿动力学分析仪及选定4组测压灌注速度、测压管牵引速度的参数组合(1mL.min-1、1mm.s-1,1mL.min-1、2mm.s-1,2mL.min-1、1mm.s-1,2mL.min-1、2mm.s-1)行静止期尿道压力测定,并对最大尿道压(max urethral pressure,MUP)、最大尿道闭合压(max closure pressure,MCP)以析因设计的F检验进行统计分析。结果 30例患者中,测压灌注速度、测压管牵引速度参数组合分别为1 mL.min-1、1mm.s-1,1mL.min-1、2mm.s-1,2mL.min-1、2mm.s-1时MUP、MCP压力值均明显低于测压灌注速度、测压管牵引速度参数组合为2mL.min-1、1mm.s-1时,差异均有统计学意义(均P<0.05)。结论不同的测压灌注速度、测压管牵引速度的组合对静止期尿道压力测定结果有明显的影响,以测压灌注速度2mL.min-1、测压管牵引速度1mm.s-1测得静止期尿道压力为较优组合。

Objective To explore the optimum combination of manometric perfusion speed and manometric tube traction speed in male resting urethral pressure measurement.Methods The resting urethral pressure was measured with urodynamic analyzer in 30 patients with benign prostatic hyperplasia.The manometric perfusion speed and manometric tube traction speed consisted of 4 parameter combinations（1 mL·min-1and 1 mm·s-1;1 mL·min-1and 2 mm·s-1;2 mL·min-1and 1 mm·s-1;2 mL·min-1and 2 mm·s-1）.Max urethral pressure（MUP） and max closure pressure（MCP）were analyzed statistically using F-test.Results The parameter combination of 1 mL·min-1and 1 mm·s-1,1 mL·min-1and 2 mm·s-1,or 2 mL·min-1and 2 mm·s-1 leaded to significant decrease in values of MUP and MCP,compared with the combination of 2 mL·min-1and 1 mm·s-1（all P0.05）.Conclusion Different combinations of manometric perfusion speed and manometric tube traction speed have obvious effects on resting urethral pressure measurement,and the optimum combination is 2 mL·min-1 of manometric perfusion speed and 1 mm·s-1 of manometric tube traction speed.
