title: [Possible causes of gas in the urinary tract].
abstract: During diagnostic procedures for various diseases, five patients underwent intravenous pyelograms which showed gas formations in the collector system, in absence of acute symptoms. Laboratory chemical, bacteriologic and radiologic examinations explained the origin of these gas formations. In one patient with diabetes mellitus and in another with an oesophageal neoplasm, infections were caused by gas forming bacteria. In three cases, bladder fistula formations were present by Crohn's disease, colon diverticulosis and a gynecological malignancy.
