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.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

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

Each component has a specific meaning:

  • Sandvik Severity Index — The sandvik severity index recorded for the scenario being assessed.
  • Combining frequency of leakage — The combining frequency of leakage recorded for the scenario being assessed.
  • Amount of leakage — The amount of leakage recorded for the scenario being assessed.

Note: Interpret the incontinence severity result against the thresholds and context described above.

How to Use

Enter the Sandvik Severity Index, combining frequency of leakage, amount of leakage for the scenario you are assessing. 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. Use the incontinence severity result to inform your calculation.
