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.
