The presence of glomerular damage was evaluated for 338 patients, adults (298) and children (40), with pulmonary or hepatic hydatid disease. A descriptive study was used. The glomerular syndrome was present in 2 children (5%) with hydatid disease, 22 adults (11%) with liver echinococcosis and 28 adults (18%) with pulmonary echinococcosis. An early stage diagnosis and proper treatment will determine the reversibility of glomerulonephritis.
