2.2 IPSS
The first official tool to systematically evaluate and measure LUTS is
the American Urology Association Symptom Index (AUA-7). It consists of
seven items that question frequency, urgency, nocturia, weak stream,
intermittent stream, straining, and incomplete emptying sensation. Each
item has five different responses rated between 0 and 5 points and with
a total score of 35 points 13. Later on, the World
Health Organization’s International Consultation on Benign Prostatic
Hyperplasia (BPH) added a quality of life item to AUA-7 and constituted
the IPSS 9. IPSS is a self-administered questionnaire,
and with this aspect, it is an easy-to-apply screening and diagnosis
tool. This symptom inquiry index, which original version is in English,
has been translated into their languages by many countries, validated,
and widely used for LUTS 14.
