Does urinary tract infection cause difficulty passing urine?

Inflammation from an infection can irritate the urethra and bladder. You may need to wait before the stream starts, pass only a small amount, or notice a weaker stream than usual. Burning while urinating, a frequent or urgent need to urinate, lower abdominal discomfort, cloudy urine, or an unusual urine smell can occur alongside these changes.

Difficulty starting or maintaining a stream is not specific to infection. A blockage, an enlarged prostate, constipation, some medicines, nerve problems, or a stone may also interfere with urine flow. A clinician may need to assess your symptoms and test a urine sample to identify the cause.

Arrange a medical assessment if the difficulty is new, persists, or occurs with burning, urgency, pelvic discomfort, or blood in the urine. Describe when it began, whether the stream stops and starts, and whether you are passing less urine than usual. Bring a list of medicines and supplements, since some can affect bladder emptying.

Drink normally unless a clinician has advised a fluid restriction. Do not use leftover antibiotics or someone else’s treatment; the correct medicine depends on the cause and, when appropriate, urine testing. Avoid delaying urination while you are waiting for advice.

Seek urgent medical help if you cannot pass urine at all, have severe lower abdominal pain or swelling, develop fever with pain in your side or back, or feel faint, confused, or very unwell. Complete inability to urinate can require prompt treatment to relieve the bladder and find the blockage or other cause.

You could ask: What might be affecting my urine flow? Do I need a urine test? Could any of my medicines contribute? What symptoms should prompt urgent review? If an infection is found, when should I expect the difficulty passing urine to improve?
