ectopic ureter

Pneumaturia is the passage of gas in the urine. In patients who have not recently had urinary tract instrumentation or a urethral catheter placed, this is almost always due to a fistula between the intestine and bladder. Common causes include diverticulitis, carcinoma of the sigmoid colon, and regional enteritis (Crohn's disease).
