- Location (kidney, upper ureter, lower ureter)
- Shape and texture of the stone
- Urinary infection or swelling
- Water intake and overall general health
- History of previous stones
Based on the above factors, in many instances, the doctor will watch the stone for a few days before making treatment recommendations. However, if the stone causes pain, and/or blockage, it would be necessary to decide upon prompt treatment.
