摘要
目的：探讨症状性BPH剩余尿（PVR）、最大尿流率（Qmax）在临床诊疗中的作用。方法：对173例BPH症患者进行IPSS、并测定Qmax、PVR及前列腺体积。应用相关分析评价各检变量间的相关性及其不同组间各指标的比较。结果：PVR与IPSS、前列腺移行带体积均呈正相关，与Qmax呈负相关。与年龄、前列总腺体积（P〉0．05）之间均无相关。PVR〈10ml组与10-30ml组在年龄、IPSS、前列腺移行带体积和Qmax比较差异均无统计学意义。PVR10-30ml组与≥30ml组在年龄、前列腺移行带体积比较差别均无统计学意义，而IPSS、Qmax比较差别有统计学意义。在Qmax〈10mL／s组，Qmax与年龄、IPSS、PVR、前列腺总体积和前列腺移行带体积均呈负相关；在Qmax〉10ml／s组，Qmax与上述指标均呈无相关（P〉0．05）；除年龄外，两组间上述指标均差异有统计学意义（P〈0．01）。结论：症状性BPH患者PVR≥30ml，Qmax〈10ml／s时，在排除其他因素引起逼尿肌损害所致的PVR增加及Qmax降低后，应及早解除膀胱出口梗阻。
Objective：To evaluate the postvoid residual urine （PVR） and maximum flow rate （Qmax） in an population of men with benign prostate hyperplasia （BPH） accompanied by lower urinary tract symptoms （LUTS）, and to assess the correlation between PVR, Qmax, urinary symptoms, prostate volum and age, and compare the difference of them in various groups. Methods：A total of 173 men with symptomatic BPH were investigated using the International Prostate Symptom Score （IPSS）, and the measurement of urinary flow rate and the prostate volume. Correlation analysis was used to determine the correlation among the variables and their variable in different groups were compared. Results：The mean age of the patients was （67.47±5.67） years, the mean IPSS score was （21.01±4.61）, the mean PVR was （26.25±33.66）, the mean Qmax was （10. 09±3.08）, the mean total prostate volume （PV）was （41.38±21.29） and the mean transition zone volume （TZV） was （24.45±16.77）. There was statistically positive correlation between PVR and age （ r = 0. 162, P = 0. 033）, IPSS scores （ r = 0. 286, P = 0. 000）, TZV （ r =0. 193, P=0. 011）, negatively correlate to Qmax（ r = - 0. 308, P = 0. 000）, but did not to PV（ P 〉0.05）. In PVR〈 10 ml group and PVR= 10-30 ml group, there were no statistically significant differences between the two groups in age , IPSS score, TZV and Qmax ; and in PVR= 10-30 ml group and PVR = 30 ml group, there were statistically significant difference between the two group inIPSS score and Qmax. There was no obvious difference in age and TZV. In the group of Qmax〈10 ml/s, there was statistically negative correlation between Q~ and age （r =- 0.307, P=0.002）, IPSS scores （r = -0.285, P = 0.004）, PVR（r=0.313, P= 0.001）, PV（r= -0.267, P=0.006） andTZV（r= -0.304, P=0.004）. In the group of Qma. 〉10 ml/s, Qmax did not correlate to them （ P 〉0. 05）. There were statistically significant differences between the two groups in IPSS score ,PVR , Qmax, PV and TZV. Conclusions：The men with PVR 〉≥ 30 ml and Qmax〈10 ml/ s in benign prostate hyperplasia （BPH） accompanied by lower urinary tract symptoms （LUTS） should be treated with surgery as soon as possible, when the other factors which cause the damages of detrusor be ruled out.
