Screening for cystocele begins with a complete medical history and physical examination—including a pelvic exam, which may show the fallen part of the bladder in the vagina. If the pelvic exam doesn’t reveal the prolapsed bladder, your doctor may perform what’s known as a voiding cystourethrogam, an x-ray or series of x-rays taken during urination that show the shape of the bladder and may identify obstructions blocking the normal flow of urine.
Other tests may also be used in diagnosing this condition—or more specifically, to detect or rule out other urinary-tract problems, including urodynamics, cystoscopy and fluoroscopy, tests that measure the bladder's functionality. Urodynamics tests measure the volume and rate of urination, use a catheter to measure the remaining volume of urine in the bladder, and in some cases fill the bladder with water via that catheter to measure how much the bladder can take before the woman feels the urge to urinate. A cystoscopy allows a doctor to use a hollow tube to view the lining of the bladder. A fluoroscopy uses a device called a fluoroscope, which allows doctors to see continuous images of the motion of internal structures.
