S37.3 Injury of urethra

Name of the Condition

• Injury of urethra

Summary

This condition involves damage to the urethra, the tube that transports urine from the bladder to the outside of the body. Urethral injuries can range from minor tears to severe disruptions, potentially affecting urinary function and requiring medical intervention.

Causes

Urethral injuries commonly result from external trauma, such as pelvic fractures, falls, or direct blows to the perineum. Penetrating injuries, including gunshot or stab wounds, may also damage the urethra. Iatrogenic causes, such as improper catheterization or surgical procedures in the pelvic region, can lead to injury.

Risk Factors

• Pelvic fractures, particularly those involving the pubic bone or pelvic ring, increase the risk of urethral injury. 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 CT scans, help visualize the extent of injury. Urinalysis may detect blood or other abnormalities. In some cases, cystoscopy is used to directly inspect the urethra.

Treatment Options

• Treatment depends on the severity of the injury. Minor injuries may be managed with catheterization to allow healing. Severe disruptions often require surgical repair, such as urethral realignment or reconstruction. Pain management and antibiotics to prevent infection are typically part of the care plan.

Prognosis and Follow-Up

Prognosis varies based on the extent of the injury and timely intervention. Early treatment improves outcomes, but some patients may experience long-term complications like strictures or incontinence. Follow-up care includes monitoring urinary function and imaging to assess healing.

Complications

• Potential complications include urethral strictures (narrowing), incontinence, erectile dysfunction (in males), and recurrent infections. Delayed treatment or severe injuries may increase the risk of these issues.

Lifestyle & Prevention

• Avoid high-risk activities that could lead to pelvic trauma. Use proper techniques during catheterization or medical procedures to minimize iatrogenic injury. Wearing protective gear during contact sports may reduce the risk of trauma.

When to Seek Professional Help

• Seek immediate medical attention if you experience blood at the urethral meatus, inability to urinate, severe pelvic pain, or signs of shock after trauma. Prompt evaluation is critical to prevent complications.

Tips for Medical Coders

• Code S37.3 is used for injuries of the urethra. Documentation should specify the type and severity of the injury (e.g., contusion, laceration, or disruption) and any associated complications. Ensure the encounter type (e.g., initial, subsequent) is clearly documented for accurate coding.
