SENSITIVITY AND SPECIFICITY OF SONOHYSTEROGRAPHY FOR THE EVALUATION OF THE UTERINE CAVITY IN PERIMENOPAUSAL PATIENTS

Sonohysterography is a technique for evaluating the uterine cavity by the instillation of sterile saline solution through an 8 Fr Foley cath eter, before performing an ultrasonographic evaluation. The sensitivit y and specificity of the procedure were evaluated in comparison to hys teroscopy In a prospective double-blind study, 47 postmenopausal patie nts were evaluated first by sonohysterography, and within 1 week by hy steroscopy. After comparing the hysteroscopic and sonohysterographic r esults, sonohysterography showed a sensitivity of 86% and specificity of 100%. Sonohysterography is an accurate mode of diagnosis for pathol ogic intrauterine processes in perimenopausal patients.
