Objective To observe the cerebral infarction after urinary retention in patients with urinary lfow dynamics related indicators of changes and investigate the intermittent catheterization combined with biofeedback electrical stimulation treatment effectiveness and mechanism of action. Methods A total of 98 patients with acute cerebral infarction with urinary retention were selected from January 2014 to January 2016. General inspection was performed on all patients. The patients were divided into treatment group (n=48) and control group (n=50) according to patients and/or the wishes of the families. The control group received sterile intermittent catheterization combined with bladder function training treatment. The treatment group received biological feedback electric stimulation therapeutic instrument based on the treatment of control group. Two groups were measured at the time of one week before and after treatment respectively, including subjective life quality of 1 W (SQLP) and urine lfow dynamics. Results Either group of urinary retention was gradually improved. The self-voiding time of treatment group after treatment for 7 times was earlier than that of the control group (P<0.01). The bladder capacity, residual urine volume and maximum urinary lfow rate of treatment group were better than control group (P<0.01). Conclusion Intermittent catheterization combined with biofeedback and electrical stimulation could better improve status of urinary retention at early stage after cerebral infarction.%目的：观察脑梗死后尿潴留患者尿流动力学相关指标的变化，探讨间歇导尿结合生物反馈电刺激治疗的有效性和作用机制。方法入选2014年1月-2016年1月急性脑梗死后尿潴留患者98例，对所有患者进行一般情况检查，根据患者和（或）家属意愿分为治疗组48例和对照组50例，对照组采用无菌间歇导尿结合膀胱功能训练治疗，治疗组在对照组基础上采用生物反馈电刺激治疗仪。分别于治疗前和治疗后1周测定两组情况，包括生活质量精简问卷评分（Subjective Quality of Life Profile，SQLP）和尿流动力学指标。结果两组的尿潴留情况均逐渐好转，治疗组经治疗7次后，恢复自主排尿时间早于对照组（P＜0.01），治疗组的膀胱容量、残余尿量和最大尿流率改善优于对照组（P＜0.01）。结论间歇导尿结合生物反馈电刺激治疗改善脑梗死后早期尿潴留状况效果更好。
