URS Outcome by Stone Burden

Predict ureteroscopy (URS) stone-free rate and procedural risk based on stone burden (total size), location, and stone composition for renal and ureteral calculi.

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

Predict ureteroscopy (URS) stone-free rate and procedural risk based on stone burden (total size), location, and stone composition for renal and ureteral calculi

Each component has a specific meaning:

  • Stone burden — The stone burden recorded for the scenario being assessed.
  • Location — The location recorded for the scenario being assessed.
  • Stone composition — The stone composition recorded for the scenario being assessed.

Note: Interpret the urs stone burden outcome result against the thresholds and context described above.

How to Use

Enter the stone burden, location, stone composition for the scenario you are assessing. Predict ureteroscopy (URS) stone-free rate and procedural risk based on stone burden (total size), location, and stone composition for renal and ureteral calculi. Use the urs stone burden outcome result to inform your calculation.
