Combined clinical and ultrasound criteria could accurately predict the Y chromosome in primary amenorrhea patient.

This study aimed to assess the combined clinical and ultrasound criteria as a diagnostic tool for screening the Y chromosome related to primary amenorrhea. This cross-sectional study involving 59 subjects was taken from medical records at the Reproductive Immunoendocrinology Polyclinic of Cipto Mangunkusumo General Hospital, Jakarta, Indonesia. The medical records of subjects were then cross-checked with karyotyping analysis results. Sensitivity, specificity, and predictive values were analyzed to assess the criteria. Two subjects were presented with a Y chromosome, and one without a Y chromosome was misclassified into another group. After analysis, we found that combined clinical and ultrasound criteria could predict the Y chromosome related to primary amenorrhea with 95.9% accuracy, with sensitivity and specificity of 80% and 97.96%, respectively. Combined clinical and ultrasound criteria (introduced as Kanadi Sumapraja Criteria) could be used as a diagnostic tool for screening a Y chromosome related to primary amenorrhea.
