How is leakage frequency scored?

Frequency: 1 = less than once per month, 2 = one or more per month but less than per week, 3 = one or more per week but not daily, 4 = every day and/or night.

How is leakage amount scored?

Amount: 1 = drops, 2 = small splashes, 3 = more than small splashes. The product of frequency and amount gives the severity index from 1-12.

Does the index distinguish stress from urgency incontinence?

The index quantifies severity but not type. A voiding diary with symptom characterization (leakage with exertion vs. sudden urge) is needed to differentiate stress, urgency, and mixed incontinence.

Urinary Incontinence Severity Index

Score urinary incontinence severity using the Sandvik Severity Index, combining frequency of leakage (1-4) and amount of leakage (1-3). Severity index = frequency multiplied by amount: 1-2 slight, 3-6 moderate, 8-9 severe, 12 very severe. Helps differentiate and quantify stress versus urgency incontinence.
