Three‐dimensional saline infusion vaginography for sonographic assessment of the anterior vaginal wall and pelvic floor descent

Abstract

Ultrasound has been recognized as an important tool for pelvic floor evaluation. A main limitation of the two-dimensional transvaginal examination is in delineation of the posterior vaginal compartment and its relation to the cervix. We describe the use of three-dimensional saline infusion vaginography as a complementary technique for the assessment of the vaginal wall and pelvic floor descent. We present several cases that demonstrate the advantages of this technique in overcoming the limitations inherent in current approaches. The improved imaging obtained by this technique enabled us to measure pelvic floor parameters and assist in evaluating pelvic floor dysfunction.
