Abstract
Wuchereria bancrofti is the major species resulting in filarial cases in India. Filariasis may present with various clinical presentations: asymptomatic, microfilaremia, lymphedema, acute adenolymphangitis and chronic lymphatic disease. Microfilariae of W. bancrofti have been detected in various clinical samples, but incidental detection of microfilaria in achylous urine is a rare finding with unexplained pathology. We report a case of microfilaria in achylous urine of a 30-year-old female who presented with pain abdomen and ureteric calculus on ultrasonography.
