Cystoscopy has a limited role in the evaluation of benign prostatic hy
perplasia (BPH). The examination is recommended in the evaluation of B
PH patients with hematuria or a history of risk factors for urethral s
tricture. Available data suggest that bladder trabeculation in BPH is
a predictor of the treatment outcome. Cytoscopy might be performed pri
or to invasive therapy to guide the urologist in choosing an operative
approach.
