目的探讨产后妇女尿流率曲线变化情况。方法采用Dantec DUETLogic尿动力学仪,对产后42～60天的224例妇女进行自由尿流率检测并绘成尿流率图。结果最大尿流率(MFR)、平均尿流率(AFR)、排尿量(VV)、达最大尿流时间(TTMR)、排尿时间(VT)和尿流时间(FT)均有明显异常改变,尿流率绘成尿流率图与正常尿流率图出现明显不同。其中初产妇及经产妇此次阴道分娩和剖宫产后自由尿流率测定结果 54%异常;初产妇阴道分娩的自由尿流率测定69%异常;初产妇剖宫产分娩的自由尿流率测定32%异常;前次阴道分娩的经产妇此次阴道分娩的自由尿流率测定71%异常;前次剖宫产的经产妇此次剖宫产分娩的自由尿流率测定34%异常。尿流率图异常类型:逼尿肌无力,腹压排尿;出口梗阻,高排高阻;出口梗阻,低排高阻;逼尿肌无力,出口梗阻,腹压排尿;协同失调,腹压排尿。结论产后进行盆底康复治疗非常必要,以防止远期尿失禁。

Objective To study the change of urinary flow rate in postpartum women. Methods The urine flow rate of 224 women after 42-60 days delivery were detected by Dantec DUETLogic urodynamics instrument. Results The urinary flow rate( MFR),average urinary flow rate( AFR),voiding volume( VV),maximum urinary flow time( TTMR),micturition time( VT) and urine flow( FT) had significantly abnormal changes. The urine flow rate chart appeared significant difference from normal urine flow rate chart. Among the cases,54% of the results of free urine flow of vaginal delivery women and cesarean section women were abnormal. The free urine flow rate of vaginal delivery women was 69% abnormal. The free urine flow rate of cesarean section women was 32% abnormal. The free urine flow rate of the previous vaginal delivery women was 71% abnormal. The free urine flow rate of the previous cesarean section women was 34 percent abnormal. The types of abnormal urine flow rate charts included deuterium muscle weakness and abdominal pressure urination,outlet obstruction and high row high resistance,outlet obstruction and low row high resistance,diuretic muscle weaknessoutlet obstruction and abdominal pressure urination,coordination disorder and abdominal pressure urination. Conclusion Postpartum pelvic floor rehabilitation treatment is essential to prevent long-term urinary incontinence.
