Abstract
OBJECTIVE: To reanalyze ultrasound images from IVF cycles with the aim of developing a refined endometrial wave classification system, which will allow description as well of the more complex endometrial wave patterns. DESIGN: Descriptive study. SETTING: University hospital-based fertility clinic. PATIENT(S): Twenty-four patients undergoing IVF. INTERVENTION(S): Ultrasound examination was performed on the day of hCG administration. MAIN OUTCOME MEASURE(S): Endometrial wave type and intraobserver and interobserver agreement. RESULT(S): Two new wave types were added to the endometrial wave types that were described in the existing wave classification system: recoiling CF waves and a standing wave. Furthermore, an alternation between CF waves and FC waves in the same fragment was described. Calculation of interobserver and intraobserver agreement resulted in a kappa value reflecting strong agreement. CONCLUSION(S): The refined endometrial wave classification system makes it possible to describe the more complex wave types that can be detected in IVF cycles on the day of hCG administration.
