What is cause of air in urine flow?

The presence of air in urine flow, often referred to as pneumaturia, can be caused by a fistula between the urinary tract and the gastrointestinal tract, allowing gas from the intestines to enter the urinary system. Other potential causes include infections, particularly with gas-forming bacteria, or certain medical procedures. If pneumaturia occurs, it is essential to seek medical evaluation to determine the underlying cause and appropriate treatment.
