S37.2 Injury of bladder

Name of the Condition

• Injury of bladder

Summary

Injury of the bladder refers to damage to the bladder wall or surrounding structures, which can range from minor contusions to severe lacerations or perforations. This condition typically results from trauma and may involve bleeding, pain, or impaired urinary function. The severity and treatment depend on the extent of the injury and whether the bladder lining is compromised.

Causes

Blunt or penetrating trauma to the abdomen or pelvis, such as from motor vehicle accidents, falls, or assaults. Surgical procedures involving the bladder or pelvic organs. Direct impact to the lower abdomen.

Risk Factors

• Participation in contact sports or activities with a high risk of abdominal trauma.
• Pre-existing bladder conditions, such as cystitis or bladder outlet obstruction.
• Advanced age, which may reduce tissue resilience.
• Recent pelvic surgery or catheterization.

Symptoms

• Lower abdominal pain or tenderness.
• Hematuria (blood in urine) or difficulty urinating.
• Swelling, bruising, or distension of the abdomen.
• Nausea, vomiting, or signs of shock in severe cases.

Diagnosis

Physical examination to assess tenderness, swelling, or external trauma. Imaging studies, including ultrasound, CT scan, or cystography, to visualize bladder damage. Urinalysis to detect blood or other abnormalities.

Treatment Options

• Conservative management, including rest and observation for minor injuries.
• Pain relief and hydration to support healing.
• Surgical intervention, such as repair or catheterization, for severe or complicated cases.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and promptness of treatment. Minor injuries often resolve with conservative care, while severe cases may require surgery and extended recovery. Follow-up may include imaging or urologic evaluation to monitor healing and prevent complications.

Complications

• Urinary retention or obstruction.
• Infection (e.g., cystitis or pyelonephritis).
• Peritonitis if the bladder perforates into the abdominal cavity.
• Long-term urinary dysfunction or incontinence.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Avoid unnecessary abdominal trauma.
• Seek prompt medical care for suspected injuries to prevent worsening.

When to Seek Professional Help

Seek immediate medical attention for severe abdominal pain, blood in urine, difficulty urinating, or signs of shock (e.g., dizziness, rapid heartbeat).

Tips for Medical Coders

Document the mechanism of injury (e.g., blunt vs. penetrating), associated symptoms (e.g., hematuria), and any imaging or procedures performed. Ensure specificity in clinical notes to support accurate coding for S37.2.
