经皮肾镜取石术肾结石计算器

How to Use 经皮肾镜取石术肾结石计算器

1. Enter total stone volume in cubic centimeters. Use the best imaging-derived burden estimate available.
2. Enter the largest single-stone diameter in millimeters and the number of stones. Larger, multiple stones add complexity points.
3. Choose renal pelvis or calyx location and whether renal pelvis abnormality is present. The result shows a risk score, expected success estimate, and planning strategy.

Formula & Theory - 经皮肾镜取石术肾结石计算器

经皮肾镜取石术肾结石计算器 uses this core formula:

Risk score = volume points + diameter points + count points + location points + renal pelvis anatomy points

The PCNL calculator is a practical scoring aid rather than a universal validated surgical scale. It translates stone burden and anatomic difficulty into points: volume captures total burden, diameter captures the dominant target size, count captures fragmentation or multiplicity, location captures access difficulty, and renal pelvis abnormality captures altered anatomy. The expected success percentage is modeled as decreasing as the score rises. It should be read as a planning prompt, not as a guarantee of stone-free status.

Use Cases for 经皮肾镜取石术肾结石计算器

• Preoperative discussion of whether a case looks straightforward, moderate, or complex.
• Comparing two imaging scenarios after updated CT or ultrasound reports.
• Explaining why calyceal stones or abnormal renal pelvis anatomy may change the operative plan.
