Can Cystoscopy Detect the Cause of Blood in the Urine?

Yes. Cystoscopy can help identify certain causes of blood in the urine (hematuria) by allowing a urologist to examine the urethra and bladder directly. However, it may not identify every possible cause, so urine tests and imaging may also be required.

Blood in the urine can occur for several reasons, including urinary tract infections, bladder or kidney stones, prostate-related conditions, and abnormalities of the urinary tract. In some cases, it may indicate a bladder or urinary tract tumour.

A urologist may recommend cystoscopy to examine the bladder lining and urethra for abnormalities such as:

• Bladder stones or other visible abnormalities

• Inflammation or changes in the bladder lining

• Suspicious growths or lesions

• Possible bleeding sites within the bladder or urethra

• Structural abnormalities affecting the urinary tract

The investigation may also include:

• Urine testing: To check for infection, blood, or other abnormalities.

• Urine culture: When a urinary infection is suspected.

• Imaging: Such as ultrasound or CT urography, depending on the patient's risk factors and clinical findings.

• Biopsy: If suspicious tissue is identified and requires laboratory examination.

A normal cystoscopy does not rule out every cause of blood in the urine, particularly conditions involving the kidneys or upper urinary tract. The complete evaluation depends on the patient's age, symptoms, medical history, and risk factors.

At SCI International Hospital, Dr. Gautam Banga evaluates patients with visible or unexplained blood in the urine to determine the appropriate investigations. When indicated, cystoscopy is used alongside other tests to identify the possible source of bleeding and guide further treatment.
