ABSTRACT
Objective To compare the effect of application of constant speed injection pump and manual injection on hysterosalpi-nography (HSG).Methods A total of 220 infertile patients were selected and classified into experimental group and control group. Then the patients were scheduled to undergo HSG.The experimental group was undergone constant speed pump injection and control group manual injection.Observe the effectiveness of the two methods on patients in two groups,respectively.Results The excellent rate of the images in experimental group (94.55%)was significantly higher than the control group (85.45%)and the risk of adverse reactions were significantly decreased in the former.There was statistical difference between the two groups.Conclusion Constant speed infusion pump is a convenient,safe and effective method in hysterosalpinography compared with manual injection,which is worthy of application in clinic.
ABSTRACT
Objective To investigate the clinical practice value of transvaginal ultrasound (TVU) combined with hysterosalpinography (HSG) in diagnosis of previous cesarean scar defect (PCSD).Methods Forty-two patients with colporrhagia,algomenorrhea or infertility after cesarean section were examined by TVU,HSG and hysteroscope.The results were compared among TVU,HSG and TVU combined with HSG.Results Among the 42 patients,21 patients were diagnosed PCSD by hysteroscope.The sensitivity of TVU was 66.7％ (14/21),specificity was 95.2％ (20/21),positive predictive value was 14/15,negative predictive value was 74.1％ (20/27).The sensitivity of HSG was 95.2％ (20/21),specificity was 100.0％ (21/21),positive predictive value was 100.0％(20/20),negative predictive value was 95.5％(21/22).The sensitivity of TVU combined with HSG was 95.2％(20/21),the sensitivity of TVU combined with HSG was significantly higher than TVU,there was statistical difference (P ＜0.05).Conclusions Compared with TVU,the sensitivity of TVU combined with HSG is increased markedly.TVU combined with HSG is a feasible clinical diagnostic method.
