摘要
目的:探讨良性前列腺增生(BPH)患者残余尿量(VRU)与膀胱出口梗阻(BOO)程度和逼尿肌收缩力的相关性。方法:临床诊断为BPH的患者152例,均行B超检查测量前列腺体积(PV)和膀胱VRU,自由尿流率检测,全套尿动力学检查评估BOO程度和逼尿肌收缩力。采用SPSS 20.0统计软件,对B超和尿动力学参数行相关性分析,两样本均数比较采用t检验,定义P<0.05有统计学意义。结果:PV与BOO程度和逼尿肌收缩力有正相关性(相关系数r=0.432和r=0.343,P<0.01)。最大尿流率(Qmax)与BOO程度负相关(r=-0.327,P<0.01),而与逼尿肌收缩力无显著相关性(r=0.123,P>0.05)。VRU≤150 ml时,VRU与逼尿肌收缩力间无显著相关性(r=0.041,P>0.05);当VRU>150 ml时,VRU与逼尿肌收缩力有显著负相关性(r=-0.490,P<0.01);VRU>300 ml时,该相关性尤为明显(r=-0.717,P<0.01)。结论:VRU对逼尿肌功能有一定预测价值。VRU>150 ml者应重视逼尿肌功能的评估,尤其是VRU>300 ml时,建议行尿动力学检查以正确评估BOO程度和逼尿肌收缩力。
Objective ： To identify the correlation of the volume of residual urine （VRU） with the severity of bladder outlet obstruction （BOO） and detrusor contractility in patients with benign prostatic hyperplasia （BPH）. Methods： A total of 152 patients with clinically diagnosed BPH underwent ultrasonography for measurement of the prostate volume and RVU, free uroflowmetry, and uro- dynamic examination for the severity of BOO and detrusor contractility. Using the software SPSS20.0, we analyzed the correlation be- tween the ultrasonographic results and urodynamic parameters and compared the two sample means by the t-test. Results： The pros- tate volume was correlated positively with BOO severity （ r = 0. 432, P 〈 0.01 ） and detrusor contractility （ r = 0. 343, P 〈 0.01 ）, while Qmax negatively with BOO severity （ r = 0. 327, P 〈 0.01 ） hut not significantly with detrusor contractility （ r = 0. 123, P 〉 0.05 ）. VRU showed a significantly negative correlation with detrusor contractility when 〉 150 ml （ r = - 0. 490, P 〈 0.01 ） , even more significantly when 〉 300 ml （ r = - 0. 717, P 〈 0.01 ） , but exhibited no significant correlation with it when ≤ 150 ml （ r = 0. 041, P 〉0. 05 ）. Conclusion ： VRU can somehow predict the detrusor function. For patients with VRU 〉 150 ml, especially for those with VRU 〉 300 ml, the detrusor function should be evaluated and urodynamic examination is recommended for exact assessment of BOO severity and detrusor contractility.
