Increased urine bubbles may be caused by: i. Higher urine solute concentration components, such as higher sugar content in the urine, or higher levels of bilirubinuria or bilirubinogen in the urine, or a large amount of protein in the urine, which can be seen during urination with water shock, producing more bubbles or foam-like changes, without painful urination or any discomfort in urination. It is recommended that routine urine or urine sediment examination be performed to clarify whether there is a high concentration of related solutes, causing foam or bubble-like changes. Second, when infection occurs in the urinary tract, such as infection with P. aeruginosa, which causes an increase in gas-producing bacteria in the urine, more bubbles can be produced during urination. Also accompanied by urinary tract irritation symptoms, such as urinary frequency, urinary urgency, painful urination, etc., further laboratory urine tests are needed to confirm the diagnosis. Third, patients who have bladder surgery or urethral surgery and have more bubbles during urination, consider the presence of vesico-enteric fistula or urethro-enteric fistula, etc. It may also discharge intestinal fluid or fecal-like tissue, which is most often seen in patients who have undergone surgery or after pelvic radiotherapy.
