Which term describes the downward profusion of the urinary bladder through the wall of the vagina?

The term that best describes the downward profusion of the urinary bladder through the wall of the vagina is "cystocele." A cystocele occurs when the bladder protrudes into the vaginal wall, often due to weakened pelvic support tissues. This can happen as a result of various factors like childbirth, aging, or strain from heavy lifting.

In contrast, a rectocele relates to the protrusion of the rectum into the vaginal wall, urethrocele involves the downward displacement of the urethra, and uterine prolapse pertains to the descent of the uterus into the vaginal canal. Therefore, "cystocele" is specifically associated with the bladder, making it the correct term for this condition. Understanding these distinctions is crucial for proper coding and diagnosis in medical settings.
