International Prostate Symptom Score (I-PSS)

Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use, so you may find the language more technical than the condition leaflets.

See separate related Benign Prostatic Hyperplasia and Lower Urinary Tract Symptoms in Men articles.

The International Prostate Symptom Score (I-PSS) is used in the assessment of lower urinary tract symptoms in men (LUTS)[1, 2, 3, 4].

The I-PSS is free for use by individual clinicians and for non-funded research. It is available on the web from Urology Specialists PC.

The I-PSS was originally based on the American Urological Association seven-item symptom score (AUA-7).[1]The 'quality of life' question was added by the World Health Organization when it was adopted by the International Consensus Committee as an international questionnaire for evaluating prostatic symptoms. Although the single 'quality of life' question may not capture the full impact of prostate symptoms, it can be used as a starting point for a doctor-patient discussion on management.
