About IBPSS

The International Bladder & Prostate Symptom Score (IBPSS) is an evolutionary step forward from the International Prostate Symptom Score (IPSS) for men with LUTS attributed to BPH.

1

“Bladder” is added to the title to ensure its role in clinical dialogue.

2

The IPSS and QoL questions are left unchanged.

3

The IPSS questions are reordered to reflect the “voiding and storage subscores.”

4

The total scores for the IPSS and the IBPSS are identical.

5

Questions for “Urgency Urinary Incontinence” and “Acute Retention” are added.

6

A “Sexual Health” question is added to reflect its importance to men.

7

The questions are arranged vertically to mirror the progression of bladder disease experienced by patients, the Man vs Prostate 5 Stages of Bladder Health.

IBPSS helps patients, and their providers, assess where they fall within the MVP 5 Stages of Bladder Health, allowing them to better inform patients of the appropriate next steps.
