Which are the symptoms of Cloacal exstrophy?

Cloacal exstrophy is a rare, complex congenital anomaly characterized by the external exposure of the bladder and intestines due to the incomplete development of the lower abdominal wall. Key symptoms include an open, bifid bladder, an exposed intestinal plate, a shortened or absent colon, and significant anatomical variations in the genitalia and pelvic floor.

What are the primary symptoms of Cloacal exstrophy?

The clinical presentation of Cloacal exstrophy, also known as the OEIS complex (Omphalocele, Exstrophy of the cloaca, Imperforate anus, Spinal defects), is highly distinct at birth. The most characteristic symptoms involve the midline abdominal structures. Infants are typically born with an omphalocele (a sac containing abdominal organs), a divided or bifid bladder, and an exposed area of the intestine, often referred to as the "intestinal plate," located between the two halves of the bladder. Because the pelvic floor is underdeveloped, the anus is typically absent or imperforate, and the external genitalia are often ambiguous or malformed.

How does the severity of symptoms vary between patients?

The spectrum of Cloacal exstrophy is wide, and the severity of symptoms depends on the extent of the structural defects present in the individual. While some patients may have relatively isolated urological and gastrointestinal findings, others experience more severe manifestations, including:

• Skeletal and spinal anomalies: A high percentage of patients have spinal cord tethering or vertebral defects, such as hemivertebrae or scoliosis.


• Renal function: The degree of kidney involvement varies; some children have normal renal function, while others may experience chronic kidney disease due to structural abnormalities in the urinary tract.


• Gastrointestinal transit: Many infants are born with a "short gut," which can lead to malabsorption issues and require long-term nutritional support.

Which symptoms most affect daily quality of life?

For individuals living with Cloacal exstrophy, the most significant daily challenges often revolve around bowel and bladder management. Because the normal anatomical structures for continence are absent or surgically reconstructed, patients often navigate long-term issues with fecal and urinary incontinence. These symptoms require complex, lifelong management strategies, including intermittent catheterization, bowel management programs, and multiple reconstructive surgeries. At DiseaseMaps.org, our community of 5 members highlights that these persistent physical challenges often require significant psychological support to manage the impact on daily social and emotional development.

When should families seek immediate medical attention?

Following the initial neonatal reconstruction, families must remain vigilant for specific complications. Immediate medical evaluation is required if a child experiences signs of urinary tract infection (fever, lethargy, cloudy or foul-smelling urine), which can be frequent in patients with Cloacal exstrophy. Additionally, any sudden changes in bowel habits, signs of intestinal obstruction (vomiting, severe abdominal pain), or new neurological symptoms—such as changes in gait or sensation that could indicate spinal cord tethering—should be addressed by a specialist immediately.

How do symptoms change or progress over time?

As a patient with Cloacal exstrophy grows, the clinical focus shifts from neonatal surgical closure to long-term functional rehabilitation. While the primary defects are addressed in the first days of life, the "symptoms" of the condition evolve into a chronic management routine. Adolescents and adults often continue to address issues related to fertility, sexual function, and the long-term integrity of their surgical reconstructions. Consistent follow-up with a multidisciplinary team—including pediatric urologists, colorectal surgeons, and geneticists—is essential to manage the transition from pediatric to adult care.

Next steps

• Consult a pediatric urologist and a colorectal surgeon experienced in complex pelvic reconstruction.


• Monitor for spinal cord tethering through regular neurosurgical consultations and imaging.
