Isolated Renal Echinococcosis with Hydatiduria in a Girl

Hydatid disease is a common occurrence in the Indian subcontinent, however involvement of kidneys constitutes only about 2-4% of cases.[1] Isolated renal involvement without involvement of liver or lung is even more rare. Associated hydatiduria is seen in only 10-20% of all cases of renal hydatidosis and involvement of ureter is rarely reported.[2] Though, due to slow evolvement and asymptomatic nature, hydatid disease is rarely seen in children, one such isolated hydatid disease of right kidney and ipsilateral ureter is reported here in an adolescent girl who presented with recurrent renal colic and gross hydatiduria.
