Why does urinary tract infection cause difficulty passing urine?

Difficulty Passing Urine is a common presentation of Urinary Tract Infection. Swelling and sensitivity around the urethra can make it harder to begin urinating or keep a steady stream. The bladder may also send urgent signals even when it contains little urine, creating a feeling of incomplete emptying. Similar symptoms can occur with prostate enlargement, a stone, constipation, medication effects, or a narrowing of the urinary passage, so they deserve individual assessment.

Contact a clinician for urinary difficulty that is new, painful, or continuing. They may check a urine sample and review other possible causes. Keep drinking normal amounts of fluid unless a clinician has restricted your intake. Try not to strain or repeatedly force urine out, as this can worsen discomfort. Avoid taking antibiotics kept from a previous illness.

Get urgent medical help if you cannot pass urine, develop severe lower abdominal pressure, have fever or shaking chills, notice pain in the flank, vomit, or feel confused or very unwell. Seek early advice if you are pregnant, have kidney disease, use a catheter, or have a condition or treatment that weakens immunity.

Ask whether you are retaining urine, whether a urine test or bladder scan is appropriate, and which symptoms should trigger urgent review. Tell the clinician about a weak stream, dribbling, blood in the urine, pelvic surgery, neurological conditions, and medicines that may affect urination.
