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 answers to this question range from
“delighted” to “terrible” or 0 to 6.
