Sensitivity and specificity of sonohysterography for the evaluation of the uterine cavity in perimenopausal patients

Abstract

Sonohysterography is a technique for evaluating the uterine cavity by the instillation of sterile saline solution through an 8 Fr Foley catheter, before performing an ultrasonographic evaluation. The sensitivity and specificity of the procedure were evaluated in comparison to hysteroscopy. In a prospective double-blind study, 47 postmenopausal patients were evaluated first by sonohysterography, and within 1 week by hysteroscopy. After comparing the hysteroscopic and sonohysterographic results, sonohysterography showed a sensitivity of 86% and specificity of 100%. Sonohysterography is an accurate mode of diagnosis for pathologic intrauterine processes in perimenopausal patients.
