Name of the Condition

• Congenital Bladder Neck Obstruction (CBNO)

Summary

Congenital bladder neck obstruction is a rare birth defect where the bladder neck, the area where the bladder joins the urethra, is blocked. This obstruction can impede the normal flow of urine from the bladder, leading to a range of urinary problems.

Causes

This condition is typically present at birth and can result from developmental abnormalities during prenatal growth. The exact cause is often unknown, but it may involve genetic and environmental factors impacting fetal development.

Risk Factors

• Genetic predispositions can increase the risk of congenital anomalies.
• Family history of urinary tract malformations.

Symptoms

• Difficulty urinating or weak urine stream.
• Frequent urinary tract infections.
• Abdominal or bladder distention.
• In severe cases, kidney problems.

Diagnosis

• Imaging studies such as ultrasound or MRI to view the urinary tract.
• Voiding cystourethrogram (VCUG) to visualize bladder and urethra during urination.
• Urodynamic studies to assess the bladder and urethra's function.

Treatment Options

• Surgical intervention to remove or bypass the obstruction, improving urine flow.
• Catheterization or stent placement to relieve blockage temporarily.
• Medications to manage symptoms like urinary infections.

Prognosis and Follow-Up

The prognosis varies depending on the severity of the obstruction and response to treatment. Early surgical intervention often leads to favorable outcomes. Regular follow-ups are crucial to monitor kidney function and urinary tract health.

Complications

• Recurrent urinary tract infections.
• Potential kidney damage or failure.
• Bladder dysfunction or urinary incontinence.

Lifestyle & Prevention

• Encourage regular medical check-ups for children with known risk factors.
• Monitor and manage urinary infections promptly to prevent complications.

When to Seek Professional Help

• Persistent urinary difficulties or abdominal pain in infants or children.
• Symptoms of urinary tract infections, such as fever and increased urination frequency.

Tips for Medical Coders

• Ensure accurate documentation of the condition's congenital nature, specified by the ICD code Q64.31.
• Avoid miscoding by distinguishing between congenital and acquired forms of bladder obstruction.
