目的 探讨压力 流率测定在老年男性排尿困难诊断中的意义。 方法 老年男性排尿困难伴前列腺增大者 12 5例 ,年龄 5 6～ 83岁 ,平均 6 8岁 ,均行尿动力学全项检查 ,对成功排尿并获得满意尿流率曲线者行压力 流率测定 ,结果分为膀胱出口梗阻 (BOO)、可疑梗阻、无梗阻 3类 ,并将逼尿肌收缩功能分为很弱、弱、正常、强烈 4级。 结果 12 5例患者中 87例获满意压力 流率测定结果 ,其中BOO 39例 ,可疑梗阻 18例 ,无梗阻 30例。BOO组、可疑梗阻组和无梗阻组的最大尿流率逼尿肌压分别为 (99.2± 34.3)cmH2 O(1cmH2 O =0 .0 98kPa)、(4 6 .9± 9.9)cmH2 O和 (30 .8± 10 .0 )cmH2 O ,膀胱开口压分别为 (99.4± 39.6 )cmH2 O、(4 3.7± 9.9)cmH2 O和 (2 9.9± 9.7)cmH2 O ,排尿期最小逼尿肌压分别为 (6 1.3± 2 7.5 )cmH2 O、(33.9± 14 .1)cmH2 O和 (2 2 .1± 12 .5 )cmH2 O ,最大逼尿肌压分别为 (113.0± 4 2 .1)cmH2 O、(5 5 .8± 14 .9)cmH2 O和 (38.4± 11.3)cmH2 O ,BOO组与无BOO组和可疑BOO组差异均有极显著性意义 (P均 <0 .0 0 1)。BOO组、可疑梗阻组和无梗阻组逼尿肌收缩功能正常级以上者分别占 74 .4 % (2 9/ 39)、2 7.8% (5 / 18)和 2 6 .7% (8/ 30 ) ,BOO组与另两组比较差异均有极显著性意义 (P?
Objective To investigate the significance of pressure flow rate in the diagnosis of dysuria in elderly men. Methods A total of 125 elderly patients with dysuria and enlarged prostate were enrolled in this study. The patients aged 56-83 years (mean age 6-8 years) were enrolled in this study. All patients underwent complete urodynamic examination. Pressure flow rate The results were divided into bladder outlet obstruction (BOO), suspicious obstruction, obstruction 3 categories, and the detrusor contraction function is divided into very weak, weak, normal, strong 4. Results Out of 125 patients, 87 patients achieved satisfactory pressure flow rate measurement, including 39 cases of BOO, suspicious obstruction in 18 cases and no obstruction in 30 cases. In the BOO group, the maximum urinary flow detrusor pressure was (99.2 ± 34.3) cmH 2 O (1 cmH 2 O = 0.098 kPa), (46.9 ± 9.9) cmH 2 O and 30.8 ± 10 .0) cmH2O, respectively. The open pressure of the bladder were (99.4 ± 39.6) cmH2O, (43.7 ± 9.9) cmH2O and (29.9 ± 9.7) cmH2O, respectively. The minimal detrusor pressure The maximum detrusor pressures were (113.0 ± 42.1) cmH2 (6 1.3 ± 2 7.5) cmH2O, (33.9 ± 14.1) cmH2O and (21.25 ± 2.5) cmH2O respectively O, (58.5 ± 14.9) cmH 2 O and (38.4 ± 11.3) cmH 2 O, respectively. There was significant difference between BOO group and non-BOO group and suspicious BOO group (all P <0.01) . In the BOO group, the rates of detrusor contractile function in the suspected obstruction group and the obstruction group were 74.4% (29/39), 7.88% (5/18) and 26.7% (8/30) respectively ), BOO group and the other two groups were significantly different (P?
