N44.0 Torsion of testis

Name of the Condition

• Torsion of Testis
• ICD-10 Code: N44.0

Summary

Torsion of testis is a urological emergency involving the twisting of the spermatic cord, which cuts off blood supply to the testicle. This condition requires immediate medical intervention to prevent testicular damage or loss. It most commonly affects adolescents but can occur at any age.

Causes

Torsion of testis typically occurs due to an anatomical abnormality that allows the testicle to rotate freely within the scrotum. This rotation twists the spermatic cord, obstructing blood flow. In some cases, trauma or physical activity may trigger the torsion, though it often happens spontaneously.

Risk Factors

• Age: Most common in males aged 12–18 years.
• Anatomical factors: Abnormal testicular attachment or a "bell-clapper" deformity.
• Family history: Genetic predisposition to testicular torsion.
• Prior torsion: History of torsion in one testicle increases risk in the other.

Symptoms

• Sudden, severe scrotal pain, often unilateral.
• Swelling or redness of the scrotum.
• Nausea or vomiting.
• Abdominal pain.
• Testicular elevation or horizontal positioning.

Diagnosis

Diagnosis is based on clinical presentation and physical examination. A Doppler ultrasound may be used to assess blood flow to the testicle. Delay in imaging should not postpone surgical exploration if clinical suspicion is high, as timely intervention is critical.

Treatment Options

• Surgical intervention: Emergency detorsion (untwisting) and orchiopexy (fixation of the testicle) to prevent recurrence.
• Manual detorsion: Temporary measure if surgery is delayed, performed by a healthcare provider.
• Orchiectomy: Removal of the testicle may be necessary if blood flow is not restored or if the testicle is nonviable.

Prognosis and Follow-Up

Prognosis depends on the duration of torsion and time to treatment. If addressed within 6 hours, testicular salvage rates are high. Delay beyond 12 hours significantly reduces the chance of preserving the testicle. Follow-up includes monitoring for complications and assessing the contralateral testicle.

Complications

• Testicular necrosis: Tissue death due to prolonged ischemia.
• Infertility: Potential long-term impact if both testicles are affected.
• Recurrence: Risk of torsion in the contralateral testicle if not fixed.

Lifestyle & Prevention

• Avoid strenuous activity that may increase torsion risk in predisposed individuals.
• Early recognition of symptoms and prompt medical care are key to preventing complications.
• Consider prophylactic orchiopexy for the unaffected testicle if torsion occurs.

When to Seek Professional Help

Seek immediate medical attention for sudden, severe scrotal pain, swelling, or redness. Do not delay care, as testicular viability decreases with time.

Tips for Medical Coders

Document the clinical presentation, timing of symptoms, and any imaging or surgical interventions. Include details on whether the torsion was intermittent or complete, and note the status of the contralateral testicle. Ensure documentation supports the urgency of the condition for accurate coding.
