Bladder Exstrophy in Children: Symptoms, Causes & Risks

A] Types of Bladder Exstrophy

The following are the types of bladder exstrophy:

• Classic Bladder Exstrophy: This is the most common form, where the bladder and associated structures (urethra and pelvic bones) are exposed outside the abdomen. The bladder cannot store urine, and affected children have continuous leakage.
• Cloacal Exstrophy: This severe variant combines bladder, intestinal, and genital abnormalities. The large intestine is split and exposed, often alongside spinal defects. Cloacal exstrophy usually requires multiple surgeries and a multidisciplinary treatment team.
• Epispadias: This is the mildest form within the exstrophy-epispadias complex, where the urethra does not develop normally. In boys, the urethral opening appears on the upper (dorsal) side of the penis, and in girls, it is located near or above the clitoris. While less severe, it still requires surgical correction and urologic care.

Each form of bladder exstrophy in children requires individualised diagnosis and long-term management by paediatric specialists. Prompt identification and planning by a paediatric urologist are crucial for improving urinary function and ensuring a better quality of life.

B] Symptoms of Bladder Exstrophy

Bladder exstrophy is often recognised at birth through easily noticeable signs:

• Visible Signs at Birth: The primary sign is the bladder exposed through the abdominal wall. In classic cases, the lower abdominal wall is open, and the bladder is visible and flattened. The umbilical cord may be positioned lower, and the genitals may appear unusual.
• Urinary Symptoms: Children with bladder exstrophy lack control over urination due to poor bladder function and absent urinary sphincters (the muscles that normally help hold in urine). These bladder control problems often lead to continuous urine leakage and an increased risk of urinary tract infections.
• Associated Physical Abnormalities: Boys may have undescended testicles, a short penis, or wide separation of the pubic bones. Girls may have a bifid clitoris or a narrow vaginal opening. Children of both genders may have genital malformations, and depending on the severity, some cases may require procedures like hypospadias surgery.
• Developmental and Growth Issues: While cognitive development is typically normal, physical growth may be delayed in some cases due to repeated surgeries, infections, or complications. Regular health evaluations are important to keep track of the child’s growth and overall health.

C] Causes of Bladder Exstrophy

• Embryological Development Errors: Bladder exstrophy arises from errors during embryonic development, specifically in the early stages when the lower abdominal wall and urogenital structures are forming. If the tissue that normally forms between the outer and inner layers of the embryo doesn’t develop correctly during the 4th to 6th week of gestation, the abdominal wall and bladder may remain open.
• Genetic and Familial Factors: Though not typically inherited, some genetic influence has been suggested. Families with one affected child have a slightly higher risk of recurrence. A few genes involved in urogenital development have been linked to bladder exstrophy, although the exact mechanisms are not fully understood. Chromosomal abnormalities have also been reported in some severe cases.
• Environmental Influences: External factors during pregnancy may also contribute. These include maternal exposure to certain medications, toxins, or infections during early pregnancy. Advanced maternal or paternal age, low birth weight, and use of assisted reproductive technologies may increase the risk, although evidence remains inconclusive.

Bladder exstrophy is a complex condition with no single known cause, making prevention difficult. Early diagnosis and timely surgery offer the best chance for healthy development and quality of life.

D] Risks Associated with Bladder Exstrophy?

• Health and Functional Risks
  Bladder exstrophy can lead to urinary incontinence, repeated urinary tract infections, and kidney complications. Surgical treatment is essential but often requires multiple procedures over time. Delayed or inadequate care may impact bladder function and overall health, making ongoing medical monitoring and timely intervention critical for managing long-term physical outcomes.
• Psychosocial and Emotional Impact
  Children with bladder exstrophy may struggle with body image, low self-esteem, and social discomfort due to visible differences or functional challenges. These emotional impacts can affect daily life as well as peer interactions. Psychological support, open communication, and family encouragement play a crucial role in promoting emotional resilience and confidence.

E] What Is the Best Treatment for Bladder Exstrophy?

Below are the best course of treatment offered in case of bladder exstrophy:

Early Diagnosis

Early diagnosis at birth, or even during prenatal scans, helps prepare for immediate intervention. A team approach involving neonatologists, paediatric urologists, and orthopaedic surgeons is ideal for planning early treatment.

Surgical Options

Treatment is primarily surgical and may follow different approaches:

• Primary closure: This is performed within the first few days of life to reposition the bladder and close the abdominal wall.
• Staged reconstruction: It involves multiple surgeries over time to address bladder closure, genital reconstruction, and urinary continence.
• One-stage repair: Combines closure and reconstruction into a single procedure.
• Pelvic osteotomy: This realigns pelvic bones for better bladder support and positioning.

Postoperative Care

Ongoing care includes bladder training, infection control, monitoring kidney function, and addressing continence. In some cases, paediatric laparoscopic surgery may be used for less invasive follow-up procedures. Supportive care includes physiotherapy, continence training, and psychosocial counselling.

The success of treatment depends on timing, surgical expertise, and long-term monitoring. With modern treatment, many children can grow up healthy and active, though lifelong follow-up is essential.
