2. What is the peak pressure at the focal zone?
3. Is the energy delivery at focal zone consistent?
4. Is the energy delivered at focal zone adequate (not more than required for stone fragmentation)?
5. Do I have enough control over the energy delivered manually?
6. Do I have enough steps of increasing energy before I reach desired energy level?
7. Does every patient require anesthesia for lithotripsy?
8. Do I have dynamic monitoring of stone during lithotripsy?
Try to grade lithotripsy unit in following category.
| Properties of lithotripsy | | Machine A | Machine B | Machine C |
| Focal zone | Larger the better | | | |
| Energy delivery at focal zone | | | | |
| Is the energy at focal zone constant | | | | |
| Control over the energy delivered manually | Does machine have manual selection of energy | | | |
| Steps of increasing energy before you reach desired energy level | More the steps better | | | |
| Patient require anesthesia (GA/SA) | Ideally no anesthesia or only analgesia should be required | | | |
| Dynamic monitoring -USG | USG is better for Lithotripsy | | | |
| Total score | | | | |
