New developments in chyluria after global programs to eliminate lymphatic filariasis

Area of Science:

• Urology
• Tropical Medicine
• Parasitology

Background:

• Chyluria is a condition characterized by the presence of chyle in the urine.
• It is predominantly caused by lymphatic filariasis, specifically Wuchereria bancrofti infestation, particularly in South Asia.
• While drug therapy with diethylcarbamazine is common, recurrences necessitate alternative treatments.

Purpose of the Study:

• To review the management strategies for chyluria.
• To highlight the role of sclerotherapy and surgical interventions for refractory cases.
• To discuss the impact of filariasis eradication programs on chyluria incidence.

Main Methods:

• Review of existing literature on chyluria management.
• Description of treatment modalities including dietary modifications, drug therapy, sclerotherapy, and surgical options.
• Discussion of the etiology, particularly lymphatic filariasis.

Main Results:

• Dietary modifications and diethylcarbamazine are first-line treatments but have high recurrence rates.
• Sclerotherapy using povidone-iodine and dextrose is effective for lymphatico-renal fistulae.
• Surgical renal hilar lymphatic disconnection offers >90% success for refractory cases, with minimally invasive techniques improving outcomes.

Conclusions:

• Sclerotherapy is a valuable option for recurrent chyluria post-drug therapy.
• Surgery remains a highly successful option for complex or recurrent cases.
• While filariasis eradication reduces incidence, chyluria management remains crucial, with a need for more effective sclerosing agents.
