To compare the diagnostic performance for tubal patency by chromopertubation and hysterosalpingography in the female infertile patients.

We prospectively evaluated 103 female patients (age range 19–35 years; mean age 27.60 years) diagnosed as infertile, underwent hysterosalpingography (HSG) for tubal patency and uterine pathology during initial diagnostic work-up. All the enlisted patients fulfilled the criteria of infertility and these also underwent hysterolaparoscopic chromopertubation (CPT). The results of HSG were compared with the reference standard using CPT.

Out of 103 female infertile patients, 60 (58.2%) were of primary and rest of them 43 (41.8%) secondary infertile patients. HSG showed abnormalities in tubal patency in 69/103 (∼67%) patients. The detected abnormalities were distributed in 40/60 (66.6%) primary and 29/43 (67.4%) secondary infertile patients. On comparison to HSG with CPT (reference standard) for tubal blockage detection, it was found that HSG was true positive (TP) in 38 patients, true negative in 34 patients, false positive in 31 patients and FN in 0 patients. We found that for detection of tubal blockage, the sensitivity, specificity, PPV, NPV and accuracy of HSG was 100.00%, 52.31%, 36.89%, 57.07% and 67% respectively. Tubal occlusion detected on HSG and CPT showed a moderate agreement (weighted kappa – 0.447; 95% CI −0.312 to 0.583). In present study, no patient shows tubal blockage in CPT while HSG was normal.

We concluded that hysterolaparoscopic mediated chromopertubation not only diagnostic but also therapeutic, so it can obviate the need of hysterosalpingography.
