A randomized study comparing air to Echovist as a contrast medium in the assessment of tubal patency in infertile women using transvaginal salpingosonography.
This study was undertaken to compare two different contrast media (air and Echovist) in the assessment of tubal patency using transvaginal salpingosonography (TSSG) in 32 infertile women referred to an infertility outpatient clinic. Altogether, 59 Fallopian tubes were examined with TSSG. Laparoscopic chromopertubation was used as a reference method. In group A (air), concordance was 90%, Cohen's kappa coefficient 0.71 [95% confidence interval (CI): 0.64-0.77], sensitivity 63%, specificity 100%, negative predictive value 88% and positive predictive value 100%. In group B (Echovist), the corresponding parameters were as follows: 93%, 0.71 (CI: 0.67-0.76), 60, 100, 93 and 100% respectively. No statistically significant differences were found between these two contrast media. Either one can reliably be used for assessing tubal patency with TSSG in infertile women as a primary phase examination modality.
