Findings from University of Sydney broaden understanding of life sciences.

According to recent research from Sydney, Australia, "We describe the use of a new sonographic technique for imaging of the posterior compartment of the pelvis: sonorectovaginography. Sonorectovaginography uses instillation of fluids (saline solution and ultrasound gel) in the vagina, pouch of Douglas, and rectum for the purpose of creating acoustic interfaces between the vagina, cervix, rectum, and pouch of Douglas."

"We performed sonorectovaginography in a woman with chronic pelvic pain during laparoscopy Urinary catheters were introduced into the rectum and vagina. Sterile saline solution was introduced into the abdominal cavity through a laparoscopic trocar and in the rectum via a rectal catheter. The transvaginal probe was then inserted, and sterile ultrasound gel was introduced into the vagina through the vaginal catheter under sonographic guidance. Sonorectovaginography has helped us create acoustic interfaces and enhanced simultaneous visualization of the vaginal walls, posterior vaginal fornix, retrocervical area, rectovaginal septum, rectal wall, and pouch of Douglas. Imaging of the posterior compartment of the pelvis is of paramount importance for identification of potentially difficult endometriosis cases, such as those complicated by obliteration of the pouch of Douglas or infiltration of the retrocervical area, rectovaginal septum, or vaginal or rectal wall," wrote T. Bignardi and colleagues, University of ...
