ICD-10: B87.81

Genitourinary myiasis, classified under ICD-10 code B87.81, refers to a parasitic infestation of the genitourinary tract by fly larvae, commonly known as maggots. This condition is relatively rare and typically occurs when flies lay eggs in or around the genital or urinary areas, leading to the development of larvae that can cause various symptoms and complications.

Clinical Description

Etiology

Genitourinary myiasis is primarily caused by certain species of flies, particularly those in the family Calliphoridae (blowflies) and Sarcophagidae (flesh flies). These flies are attracted to decaying organic matter, including wounds or necrotic tissue, and can inadvertently infest healthy tissue if conditions are favorable, such as poor hygiene or underlying health issues that lead to skin breakdown.

Symptoms

Patients with genitourinary myiasis may present with a range of symptoms, including:

• Local Discomfort: Patients often report pain or discomfort in the affected area.
• Inflammation and Swelling: The presence of larvae can lead to localized inflammation, resulting in swelling and redness.
• Discharge: There may be a purulent or foul-smelling discharge from the affected area, which can be indicative of secondary bacterial infection.
• Pruritus: Itching is a common symptom due to irritation caused by the larvae.
• Dysuria: If the urinary tract is involved, patients may experience painful urination.

Diagnosis

Diagnosis of genitourinary myiasis typically involves a clinical examination, where the presence of larvae can often be visually confirmed. Additional diagnostic methods may include:

• Microscopic Examination: Identifying larvae in discharge or tissue samples.
• Imaging Studies: In some cases, imaging may be used to assess the extent of tissue involvement.

Treatment

The primary treatment for genitourinary myiasis involves the removal of the larvae, which can be achieved through:

• Manual Extraction: In many cases, larvae can be removed manually.
• Surgical Intervention: More extensive infestations may require surgical debridement to remove necrotic tissue and larvae.
• Antibiotics: If there is a secondary bacterial infection, appropriate antibiotic therapy may be necessary.

Prevention

Preventive measures focus on maintaining good hygiene and addressing any underlying conditions that may predispose individuals to infestations. This includes:

• Proper Wound Care: Ensuring that any wounds are kept clean and covered.
• Hygiene Practices: Regular bathing and personal hygiene can help reduce the risk of fly attraction.

Conclusion

Genitourinary myiasis, while uncommon, poses significant health risks if not promptly diagnosed and treated. Awareness of the condition, its symptoms, and preventive measures can help mitigate the risk of infestation. For healthcare providers, recognizing the signs of myiasis is crucial for effective management and patient care.
