Bloody urine after cystoscopy: what to expect and when to get help

The cystoscope passes through the urethra into the bladder, so minor irritation can cause brief spotting. Bleeding may be more noticeable if a biopsy or another procedure was performed at the same time.

Urine may look pale pink, red-tinged, or contain a small streak after the instrument has touched the lining of the urinary passage. Mild burning and a frequent urge to urinate can occur alongside this irritation and should ease rather than intensify.

Blood after the test reflects the recent procedure; by itself, it does not establish what the cystoscopy found. Your urology team should explain any visual findings, samples taken, and planned follow-up separately.

Follow the discharge instructions from your procedure team. If you have not been told to restrict fluids because of a heart, kidney, or other condition, regular water intake can help dilute the urine. Rest if the procedure or anaesthetic has left you tired.

Observe whether the urine is becoming clearer and whether you can pass urine normally. Contact the treating clinic if bleeding is not settling, returns after clearing, or differs from the recovery pattern they described.

Get urgent medical help for heavy bleeding, repeated blood clots, increasing lower abdominal pain, fever or chills, cloudy or foul-smelling urine, or worsening pain when urinating. These features can signal significant bleeding, infection, or another complication.

Go to an emergency department if you cannot pass urine and your lower abdomen is becoming swollen or painful. Tell the clinician that you recently had a cystoscopy and whether a biopsy or treatment was performed.

Ask how much bleeding is expected for your specific procedure, whether tissue was sampled, when normal activity can resume, and whom to contact outside clinic hours. Also confirm when and how you will receive the cystoscopy or biopsy results.
