Bulging of the posterior vaginal wall is best detected by which examination technique?

• A. Pelvic exam and valsalva maneuver
• B. Bulbocavernosus reflex assessment
• C. Pelvic muscle strength evaluation
• D. Simple or bedside cystometrogram

Answer: (A)

A rectocele is best detected during a dynamic pelvic examination. When the patient bears down with a Valsalva maneuver, the increased intra-abdominal pressure pushes the rectum toward and into the posterior vaginal wall, creating a bulge that can be seen or felt. This makes the posterior compartment prolapse most apparent and confirms bulging of the posterior vaginal wall. The other assessments focus on nerve function, pelvic floor muscle strength, or bladder function, and do not reveal a posterior wall prolapse.
