N44.02 Intravaginal torsion of spermatic cord

Name of the Condition

• Intravaginal Torsion of Spermatic Cord
• ICD-10 Code: N44.02

Summary

Intravaginal torsion of the spermatic cord is a urological condition characterized by the twisting of the spermatic cord within the vaginal tunic, leading to compromised blood flow to the testicle. This condition is a subset of testicular torsion and requires prompt evaluation to prevent testicular ischemia or infarction. It typically occurs in adolescents and young adults but can affect males of any age.

Causes

Intravaginal torsion of the spermatic cord is often due to an anatomical abnormality, such as a "bell-clapper" deformity, which allows the testicle to rotate freely within the scrotum. This rotation twists the spermatic cord, obstructing venous and arterial blood flow. The condition may be triggered by physical activity, trauma, or occur spontaneously without a clear precipitating event.

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. Additional imaging or laboratory tests are rarely needed.

Treatment Options

Treatment involves immediate surgical intervention to untwist the spermatic cord and restore blood flow. If the testicle is viable, it is fixed to the scrotal wall (orchiopexy) to prevent recurrence. If the testicle is nonviable, orchiectomy (removal) may be necessary. Postoperative care includes monitoring for complications and pain management.

Prognosis and Follow-Up

Prognosis depends on the duration of torsion and the viability of the testicle. Early intervention improves outcomes, preserving testicular function. Follow-up care includes monitoring for recurrence and assessing hormonal or fertility impacts. Long-term follow-up may be recommended for patients with bilateral torsion or prior history.

Complications

• Testicular infarction or necrosis.
• Infertility due to loss of testicular function.
• Recurrent torsion if orchiopexy is not performed.
• Psychological distress related to testicular loss.

Lifestyle & Prevention

While prevention is limited, awareness of risk factors and prompt recognition of symptoms can reduce complications. Avoiding high-risk activities without protective measures may be advised, though torsion often occurs spontaneously. Regular self-examinations are not typically recommended but may help in early detection.

When to Seek Professional Help

Seek immediate medical attention for sudden, severe scrotal pain, swelling, or redness. Delay in care can lead to permanent testicular damage. Emergency services should be contacted if symptoms are accompanied by nausea, vomiting, or abdominal pain.

Tips for Medical Coders

Document the clinical findings, including the presence of scrotal pain, swelling, or physical exam findings consistent with torsion. Note any imaging results (e.g., Doppler ultrasound) and surgical interventions. Ensure the code N44.02 is used when the torsion is specifically intravaginal and not extravaginal. Include details of orchiopexy or orchiectomy if performed.
