Endoscopic treatment of refractory filarial chyluria: a preliminary report.

Abstract

We report our experiences treating 5 patients who had filarial chyluria using an endoscopic approach. Two men and 3 women 47 to 83 years old with chyluria were treated with endoscopic coagulation using guide tube methods. Intrarenal pelvic instillation of silver nitrate was not effective in 4 patients and catheterization was impossible in 1. The responsible lesion was successfully coagulated in all 5 patients. Because the lesion was in the ruptured portion of the caliceal fornix, we thought that chyluria had arisen in the fragile portion of the fornix (fistulization). After endoscopic treatment there was no recurrence in any patient. Endoscopy is effective and minimally invasive therapy for filarial chyluria.
