Role of sonohystrography in checking caesarean section scars

ABSTRACT

Optimally performed hysterosalpingography and saline infusion sonohysterography can be relatively comfortable procedures for the patient that provide a great deal of useful diagnostic information. Thirty patients were divided into 2 groups Group I [15 patients] had normal healthy uterine wall scar detected by hystroscopy, group 11[15 patients] had a uterine wall defect detected by hysteroscopy at the site of CS. Transvaginal sonohysterographic evaluation was done after slow intrauterine infusion of 10 to 20 ml of sterile isotonic saline. This results in a sensitivity of 93.33% specificity of 86.67%, positive predictive value of 87.5%, negative predictive value of 92.86% and an overall accuracy of 90% for sonohystrographic examination in diagnosing the presence of a uterine wall defect after CS. Transvaginal ultrasound holds promise as a useful tool for trying to answer important clinical questions in prospective trials
