I expel gases through the urinary tract, is it serious? 

The expulsion of gases through the urine may indicate the existence of a fistula of the urinary tract and the digestive tract. This is a communication between the two. In itself it is not serious. It may be associated with an increase in urinary tract infections. A proper study of the origin of the fistula is necessary, which may be related to urological processes such as previous surgeries or digestive processes such as infections or diverticulitis.
