NCLEX Review Guide: Bladder Exstrophy in Pediatric Patients

Understanding Bladder Exstrophy

• Bladder exstrophy is a rare congenital anomaly where the bladder develops outside the abdominal wall, exposing the bladder mucosa and causing the pubic bones to be widely separated.
• This condition occurs in approximately 1 in 30,000-50,000 births and is more common in males than females (2:1 ratio).
• The exposed bladder appears as a red, raw, granular mass on the lower abdomen with urine constantly draining from ureteral orifices.
• Associated anomalies include epispadias, inguinal hernias, and potential kidney abnormalities requiring comprehensive assessment.

Immediate Postbirth Care

1. Cover exposed bladder immediately with sterile, non-adherent dressing or plastic wrap to prevent drying and infection
2. Apply sterile saline-soaked gauze over the plastic covering to maintain moisture and prevent tissue damage
3. Position infant prone or side-lying to minimize pressure on the exposed bladder and reduce contamination risk
4. Monitor for signs of infection including increased redness, purulent drainage, or elevated temperature
5. Document urine output, color, and any changes in bladder appearance every 2-4 hours

Ongoing Care Priorities

• Maintain strict aseptic technique during all dressing changes and bladder care to prevent ascending urinary tract infections.
• Monitor skin integrity around the exposed area, applying barrier creams or protective devices to prevent excoriation from constant urine exposure.
• Assess fluid and electrolyte balance as continuous urine loss can lead to dehydration and electrolyte imbalances.
• Provide emotional support to parents, explaining the condition and surgical plan while addressing their concerns and fears.

Staged Surgical Repair

• Primary closure is typically performed within 48-72 hours of birth when tissue is most pliable and before significant scarring occurs.
• The procedure involves closing the bladder, reconstructing the abdominal wall, and bringing the pubic bones together (osteotomy may be required).
• Postoperative care includes maintaining bladder decompression via catheter, monitoring for bleeding, and ensuring proper wound healing.
• Secondary procedures may be needed to address epispadias repair and achieve urinary continence as the child grows.

Potential Complications

• Infection risk remains high due to proximity to anal opening and potential for contamination during diaper changes.
• Kidney damage may occur from chronic infection or reflux, requiring ongoing urological monitoring and possible prophylactic antibiotics.
• Incontinence issues may persist, requiring additional surgical interventions and long-term bladder training programs.
• Psychological impact on child and family requires ongoing support and counseling as the child develops body awareness.
