N45.4 Abscess of epididymis or testis

Name of the Condition

• Abscess of epididymis or testis

Summary

Abscess of the epididymis or testis is a localized collection of pus within the epididymis (the coiled tube behind the testicle) or the testis itself. This condition typically results from infection and causes pain, swelling, and inflammation in the scrotum. It may affect one or both sides and requires prompt medical attention to prevent complications.

Causes

Abscesses in the epididymis or testis are most commonly caused by bacterial infections, including sexually transmitted infections (e.g., chlamydia, gonorrhea) or urinary tract infections. Less frequently, they may arise from hematogenous spread of bacteria, trauma to the scrotum, or as a complication of epididymitis or orchitis. In some cases, the infection may be polymicrobial or associated with underlying conditions like diabetes.

Risk Factors

• Recent or recurrent urinary tract infections or sexually transmitted infections.
• History of epididymitis or orchitis.
• Trauma to the scrotum or testicular region.
• Immunocompromised states (e.g., diabetes, HIV).
• Recent surgical procedures involving the genitourinary tract.

Symptoms

• Sudden or progressive pain and swelling in the scrotum, often localized to one testicle.
• Redness and warmth of the scrotal skin.
• Fever or chills.
• Difficulty walking or sitting due to discomfort.
• Possible discharge or drainage if the abscess ruptures.

Diagnosis

Diagnosis typically involves a physical examination to assess scrotal tenderness, swelling, and warmth. Urinalysis and urine culture may identify bacterial pathogens. Imaging, such as scrotal ultrasound, is often used to confirm the presence of an abscess, evaluate its size, and rule out other conditions like testicular torsion or tumor. Blood tests may be performed to check for signs of infection or inflammation.

Treatment Options

Treatment usually includes antibiotics targeted at the identified or suspected bacteria. For larger or persistent abscesses, surgical drainage may be necessary. Supportive care, such as scrotal elevation, cold compresses, and pain management, is often recommended. In cases of severe infection, hospitalization and intravenous antibiotics may be required.

Prognosis and Follow-Up

With appropriate treatment, most abscesses resolve without long-term complications. Follow-up care may include repeat imaging to ensure the abscess has healed and monitoring for recurrence. Patients should be advised to complete the full course of antibiotics and seek care if symptoms worsen or persist.

Complications

• Spread of infection to surrounding tissues or the bloodstream (sepsis).
• Chronic pain or scrotal discomfort.
• Infertility, particularly if the epididymis is severely damaged.
• Testicular atrophy or loss of function in severe cases.
• Recurrence of abscesses.

Lifestyle & Prevention

• Practice safe sex to reduce the risk of sexually transmitted infections.
• Maintain good hygiene of the genital area.
• Seek prompt treatment for urinary tract infections or scrotal injuries.
• Manage underlying conditions like diabetes to support immune function.
• Avoid activities that may cause scrotal trauma.

When to Seek Professional Help

Seek immediate medical attention if you experience sudden, severe scrotal pain, fever, or swelling, as these may indicate a serious infection or abscess. Prompt evaluation is critical to prevent complications and ensure appropriate treatment.

Tips for Medical Coders

When coding for abscess of the epididymis or testis (N45.4), ensure documentation specifies the location (epididymis, testis, or both) and confirms the presence of an abscess. Note any associated infections, trauma, or procedures (e.g., drainage) to support code assignment. Verify that the diagnosis aligns with clinical findings and imaging results.
