Cloacal Deformities | Testing & Diagnosis

How are cloacal deformity diagnosed?

In some instances, cloacal deformities can be diagnosed before birth with a prenatal ultrasound, which may be confirmed by magnetic resonance imaging (MRI). After birth, your baby’s doctor can make or confirm this diagnosis with a physical examination.

Your baby’s physician will likely conduct a careful analysis of structures of the upper urinary system and sacrum, as well as perineal and pelvic anatomy, using some combination of the following diagnostic imaging studies:

  • Magnetic resonance imaging (MRI).
  • Examination under anesthesia and endoscopy. This involves the insertion of a small instrument called an endoscope to view the interior of a hollow organ, such as the rectum, urethra or vagina.
  • Special types of X-ray tests called fluoroscopy studies. These include a 3D cloacagram, voiding cystourethrogram, and contrast enema.
  • Abdominal ultrasound (sonography). This imaging method is used to view the anatomy of the internal organs as they function, and to assess blood flow.
  • X-rays

We may also recommend that your child undergo evaluation for esophageal, vertebral, tracheal, radial or cardiac anomalies that are sometimes associated with cloacal deformities.
