Leaking bloody urine: what to do

Blood may appear pink, red, or brown, and it can occur with burning, urgency, a weak stream, pain in the side or back, or clots. A urinary tract infection may irritate the bladder and cause painful frequent urination. Stones can scratch the urinary tract and cause severe side or groin pain. Benign prostate enlargement may affect flow and bladder emptying in some men. Strenuous activity, medicines that affect clotting, or bleeding from another source can also confuse the picture.

Visible blood is different from urine leakage alone: both symptoms should be described. A clinician may check a urine sample, review medicines, examine you, and decide whether imaging or specialist assessment is needed.

Contact a clinician promptly, even if the blood has stopped. Note when it began, its colour, whether clots were present, and any pain, fever, burning, change in flow, or recent injury. Bring a list of medicines and supplements, especially those that affect clotting. Drink normally unless a clinician has given you another plan; do not use leftover antibiotics.

If you are menstruating or have another possible source of bleeding, mention that when arranging assessment. It may help the clinician interpret a urine sample, but it should not delay advice when blood is clearly seen in urine.

Go to urgent care if you cannot pass urine, pass clots, have heavy or ongoing bleeding, severe side or back pain, fever with shaking chills, repeated vomiting, faintness, or marked weakness. Seek emergency help for confusion or collapse. These features can signal blockage, significant infection, or another problem needing rapid treatment.

Ask what tests are appropriate, whether infection or a stone is possible, and whether any medicine could be contributing. If you have weak flow or difficulty emptying, ask whether benign prostate enlargement is relevant. Ask what symptoms should send you back urgently and when results will be reviewed.
