Cystoscopy in Men and the Prostate

A clinician guides a thin viewing instrument through the opening of the penis and along the urethra into the bladder. The instrument does not enter the prostate itself; it passes through the portion of the urethra surrounded by the prostate.

Because the prostate sits around part of the urethra, enlargement or irregular tissue can change the shape and width of that channel. During cystoscopy, the clinician may see narrowing, obstruction, bleeding, stones, inflammation, or changes inside the bladder that help explain urinary symptoms.

The examination can provide visual information, but it does not by itself settle every prostate diagnosis. Other assessment may include a symptom history, urine testing, a physical examination, imaging, or tissue sampling, depending on the reason for the procedure.

Tell the care team about medicines that affect bleeding, allergies, previous urinary infections, difficulty passing urine, and any earlier reaction to anesthesia or sedation. Follow the clinic's instructions about eating, drinking, regular medicines, and whether someone must take you home.

After a straightforward examination, mild burning during urination, urgency, or a small amount of blood can occur for a short time. Drink fluids if your clinician has not restricted them, and use only the pain relief recommended for you.

Contact the treating team promptly if you cannot pass urine, develop fever or chills, have worsening lower abdominal pain, pass clots, or notice bleeding that is heavy or increasing. These features need assessment because they may indicate urinary retention, infection, or significant bleeding rather than expected irritation.

Ask what the examination is intended to clarify, whether a flexible or rigid scope is planned, what comfort medicine will be used, and whether treatment or a biopsy might occur at the same appointment. Also confirm when results will be explained and whom to contact if urination becomes difficult afterward.
