S37.32 Contusion of urethra

Name of the Condition

• Contusion of urethra

Summary

This condition involves bruising or swelling of the urethra, the tube that transports urine from the bladder to the outside of the body. Contusions may result from blunt trauma and can affect urinary function, though they are generally less severe than complete tears or lacerations.

Causes

Urethral contusions typically occur due to direct blunt force trauma, such as falls, pelvic fractures, or blows to the perineum. Penetrating injuries, including gunshot or stab wounds, may also cause contusions. Iatrogenic factors, such as improper catheterization or pelvic surgery, can lead to this type of injury.

Risk Factors

• Pelvic fractures, particularly those involving the pubic bone or pelvic ring, increase the risk of urethral contusion. High-impact activities, motor vehicle accidents, and contact sports are associated with higher rates of trauma. Males are more frequently affected due to anatomical differences.

Symptoms

• Blood at the urethral meatus (opening), difficulty or inability to urinate, pain during urination, swelling or bruising in the genital or pelvic area, and possible blood in the urine (hematuria). Severe cases may present with signs of shock or perineal hematoma.

Diagnosis

Diagnosis involves a physical examination to assess for swelling, bruising, or blood at the urethral meatus. Imaging studies, such as retrograde urethrography or cystoscopy, may be used to evaluate the extent of the injury and rule out more severe damage like lacerations or complete disruption.

Treatment Options

Treatment focuses on managing symptoms and preventing complications. This may include catheterization to allow urine to flow without irritating the injury, pain management, and monitoring for signs of worsening damage. Severe cases may require surgical intervention.

Prognosis and Follow-Up

The prognosis for urethral contusion is generally good, especially with prompt treatment. Most patients recover without long-term complications, but follow-up care may be necessary to ensure proper healing and assess urinary function. Regular monitoring helps detect any delayed issues.

Complications

Potential complications include urinary retention, infection, or the development of strictures (narrowing) of the urethra. In rare cases, untreated contusions may progress to more severe injuries requiring additional intervention.

Lifestyle & Prevention

Avoid high-risk activities that may lead to pelvic trauma, such as contact sports without proper protection. Use caution during falls or accidents, and ensure proper technique during medical procedures involving the urethra to minimize injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience blood at the urethral meatus, inability to urinate, severe pain, or signs of shock (e.g., dizziness, rapid heartbeat) after trauma to the pelvic area.

Tips for Medical Coders

When coding for contusion of the urethra (S37.32), ensure documentation supports the diagnosis, including details of the injury mechanism and clinical findings. Verify that the code aligns with the specific type of urethral injury and any associated complications.
