Pneumaturia
Pneumaturia is the passage of gas or "air" in urine. This may be seen or described as "bubbles in the urine".

Causes
A common cause of pneumaturia is colovesical fistula (communication between the colon and bladder). These may occur as a complication of diverticular disease. Pneumaturia can also happen if a urinary catheter was recently in the bladder.
Other key differentials:
- Crohn's disease
- Carcinoma of the colon or bladder
- A gas-producing UTI (emphysematous cystitis: rare).
- Emphysematous pyelonephritis.
Male scuba divers utilizing condom catheters or female divers using a She-p external catching device for their dry suits are also susceptible to pneumaturia.[1]
Diagnosis
Diagnosis is made by patient history of passing air or a sputtering urine stream. CT scans may show air in the urinary bladder or bladder walls.
