Can Cystoscopy Detect an Enlarged Prostate?

Cystoscopy can help a urologist assess how an enlarged prostate may be affecting the urethra and bladder outlet. However, it does not measure the overall size of the prostate as accurately as imaging, and other tests are often needed to evaluate benign prostatic hyperplasia (BPH).

The prostate gland surrounds part of the urethra. When it enlarges, it can compress the urethra and obstruct the flow of urine.

A urologist may recommend cystoscopy when symptoms suggest that an enlarged prostate is affecting urination, particularly if further evaluation of the bladder outlet is needed.

Symptoms may include:

• Weak or interrupted urine stream

• Difficulty starting urination

• Frequent urination, especially at night

• Urinary urgency

• A feeling of incomplete bladder emptying

• Urinary retention

During cystoscopy, the urologist examines the urethra, the area where the prostate surrounds the urethra, and the bladder outlet. This can reveal obstruction, changes in the bladder, or other abnormalities.

However, cystoscopy alone cannot confirm the full size of the prostate or establish BPH as the sole cause of symptoms. Assessment may also include a medical history, physical examination, urine tests, prostate imaging, and measurement of urine flow or post-void residual urine.

SCI International Hospital

At SCI International Hospital, Dr. Gautam Banga evaluates urinary symptoms and determines whether cystoscopy is needed to assess possible prostate-related obstruction. Findings are considered alongside other investigations to help guide an appropriate treatment plan.
