Current methods of tubal patency assessment.

OBJECTIVE

To evaluate the scientific literature on current methods of uterine cavity and tubal patency assessment.

DESIGN

Review of literature and appraisal of relevant articles using MEDLINE, OVID, EMBASE, and Cochrane on-line databases.

RESULT(S): Current pelvic imaging subfertility investigations are compared with the gold standard laparoscopy. The technical aspects, associated risks, potential advantages, and weighted utility of each screening study are discussed. A comprehensive analysis of the clinical evidence regarding the safety, tolerance, and accuracy of hysterosalpingo-contrast sonography compared with alternative screening studies and/or laparoscopy is reviewed.

CONCLUSION(S): Increasing evidence supports the more recently described hysterosalpingo-contrast sonography procedure as an acceptable screening study for the subfertile patient with the potential advantage that it is a comprehensive evaluation, methodologically simple, cost effective, and time efficient.
