Non-parasitic chyluria (presenting with urinary retention)

Area of Science:

• Urology
• Vascular Surgery
• Lymphatic System Research

Background:

• Non-parasitic chyluria is a rare condition characterized by the presence of chyle in the urine.
• Urinary retention can be a presenting symptom of chyluria.
• Filariasis is a common cause of chyluria, but non-parasitic forms exist.

Purpose of the Study:

• To present two cases of non-parasitic chyluria with urinary retention.
• To investigate the underlying cause of the chyluria using lymphangiography.
• To evaluate the efficacy of surgical intervention for this condition.

Main Methods:

• Diagnostic lymphangiography was performed to identify abnormal lymphatic communications.
• Surgical excision of anomalous dilated lymphatic vessels was conducted.
• Patients were followed for symptom resolution and long-term outcomes.

Main Results:

• Lymphangiography revealed abnormal lymphatic communications in both patients.
• The thoracic ducts were patent, and no evidence of filariasis was found.
• Surgical removal of the anomalous lymphatics resulted in complete symptom resolution.

Conclusions:

• Lymphatic malformations may be the underlying cause of non-parasitic chyluria.
• Surgical management of these lymphatic abnormalities can lead to long-term symptom relief.
• This approach offers a potential treatment for non-parasitic chyluria unresponsive to other methods.
