Routine radio-imaging in filarial chyluria--is it necessary in developing countries?
Chyluria is a common presentation of filariasis in developing countries and mostly affects economically poor classes. The judicious use of investigations is mandatory to keep the cost of treatment acceptable. A modified plan is suggested for managing such patients without using retrograde pyelography or lymphangiography. A total of 54 patients were studied at 2 separate institutions, with retrograde pyelography being carried out at one institution but not at the other. All patients were treated primarily by the instillation of 1% silver nitrate, with an initial success rate of 70%. Eight patients who failed to respond underwent pyelolymphatic disconnection, the success rate being 88%. The omission of retrograde pyelography and lymphangiography had no effect on either treatment or outcome. The value of these radio-imaging techniques is discussed.
