This questionnaire has been developed by experts of the International Consultation on Prostatic Diseases, and is universally accepted as a tool for objective assessment of urinary symptoms related to an enlarged prostate gland (prostatic hypertrophy). The questionnaire does not provide any indication of the presence or absence of a cancerous disease of the prostate. The questionnaire,do not in any way replace the medical examination which remains the essential tool for the evaluation of patients with prostatic hypertrophy.

About the I-PSS

The International Prostate Symptom Score (I-PSS) is based on the answers to seven questions concerning urinary symptoms and one question concerning quality of life. Each question concerning urinary symptoms allows the patient to choose one out of six answers indicating increasing severity of the particular symptom. The answers are assigned points from 0 to 5. The total score can therefore range from 0 to 35 (asymptomatic to very symptomatic).

The questions refer to the following urinary symptoms:

Questions Symptom
1 Incomplete emptying
2 Frequency
3 Intermittency
4 Urgency
5 Weak Stream
6 Straining
7 Nocturia

Question eight refers to the patient’s perceived quality of life.

The first seven questions of the I-PSS are identical to the questions appearing on the American Urological Association (AUA) Symptom Index which currently categorizes symptoms as follows:

Mild (symptom score less than of equal to 7) Moderate (symptom score range 8-19) Severe (symptom score range 20-35)

The International Scientific Committee (SCI), under the patronage of the World Health Organization (WHO) and the International Union Against Cancer (UICC), recommends the use of only a single question to assess the quality of life. The answers to this question range from “delighted” to “terrible” or 0 to 6. Although this single question may or may not capture the global impact of benign prostatic hyperplasia (BPH) Symptoms or quality of life, it may serve as a valuable starting point for a doctor-patient conversation.

The SCI has agreed to use the symptom index for BPH, which has been developed by the AUA Measurement Committee, as the official worldwide symptoms assessment tool for patients suffering from prostatism.

The SCI recommends that physicians consider the following components for a basic diagnostic workup: history; physical exam; appropriate labs, such as U/A, creatine, etc.; and DRE or other evaluation to rule out prostate cancer.
