Removing kidney stones often requires a procedure called percutaneous nephrolithotomy. This surgery involves making a small hole in the back to reach the stone. Doctors must aim carefully to hit the target without causing harm. A new device called a CT-Guided Puncture Device might make this task easier. It helps doctors see exactly where to aim using a computer scan. This report looks at how this tool compares to older methods that rely on free-hand aiming or X-rays alone.
The study involved 51 adult patients. Doctors used the new device for some and traditional methods for others. The results showed the new tool worked very well. It reduced the time needed to make the puncture. It also lowered the number of times doctors had to try to hit the target. Success rates were perfect in this group. Patients received less radiation exposure and fewer CT scans when the new device was used.
This approach seems especially helpful for doctors who are learning this skill. It gives them a steady hand to aim at the stone. The report notes that radiation levels dropped by 11.2 percent compared to free-hand methods. The number of CT scans used dropped by 23.6 percent. These changes mean less radiation for the patient and less time spent in the operating room.
However, this is a preliminary report with a small group of 51 people. That means the results are early and not yet fully proven for everyone. We do not know about long-term safety or outcomes for larger groups yet. This data is a promising start but needs more testing before it becomes standard practice everywhere.
