Diagnostic assessment of benign prostatic hyperplasia

Clinical evaluations of benign prostatic hyperplasia (BPH) are based upon careful history taking, uroflowmetry, palpation of the prostate, and diagnosis of urinary infection or possible damage to the kidneys caused by outflow obstruction. Symptom assessment includes scoring by the patient of the four obstructive and five irritative symptoms of prostatic obstruction: a simple questionnaire is used. The scoring system should be reviewed with the urinary flow measurements as part of the workup. The various forms of ultrasound used for diagnosis, although invaluable, may not be assessed out of context, and the combination of digital palpation and endoscopy generally provide most information leading to a decision for operation. When available, perrectal ultrasound scanning should be used to investigate palpable abnormalities and to identify unexpected prostatic cancer.
