S37.22 Contusion of bladder

Name of the Condition

• Contusion of bladder

Summary

Contusion of the bladder refers to a bruise or superficial injury to the bladder wall without full-thickness disruption. This condition typically results from trauma and may involve localized bleeding, pain, or temporary urinary symptoms. The severity and treatment depend on the extent of the injury and whether underlying structures are affected.

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 with pain relief and monitoring for complications. Catheterization if urinary retention occurs. Surgical intervention if severe injury or associated damage is present.

Prognosis and Follow-Up

Most contusions resolve with conservative care, but follow-up may be needed to ensure no progression to more severe injury. Monitoring for hematuria and urinary function is typical during recovery.

Complications

Hemorrhage, infection, or progression to bladder rupture. Long-term urinary dysfunction or scarring in severe cases.

Lifestyle & Prevention

Avoid high-risk activities without proper protection. Use seatbelts and avoid falls. Maintain bladder health through hydration and prompt treatment of infections.

When to Seek Professional Help

Severe abdominal pain, inability to urinate, or signs of shock (e.g., dizziness, rapid heart rate). Persistent hematuria or worsening symptoms after initial care.

Tips for Medical Coders

Document the mechanism of injury, clinical findings (e.g., hematuria, pain), and imaging results to support the diagnosis. Ensure the code S37.22 is used for confirmed contusion without associated laceration or perforation.
