Body mass index (BMI), surgical success rate, and tract number significantly impact fluoroscopy screening time (FST) and radiation dose (RD) during complete supine percutaneous nephrolithotomy (csPCNL). Understanding these factors aids surgeons in minimizing radiation exposure through preoperative planning.
Area of Science:
- Urology
- Medical Imaging
- Nephrology
Background:
- Fluoroscopy-guided percutaneous nephrolithotomy (PCNL) is a primary treatment for large kidney stones.
- Minimizing fluoroscopy screening time (FST) and radiation dose (RD) is crucial for patient safety during PCNL.
Purpose of the Study:
- To identify factors influencing FST and RD in patients undergoing complete supine PCNL (csPCNL).
- To provide insights for optimizing surgical planning and reducing radiation exposure.
Main Methods:
- An analytic cross-sectional study involving 355 patients who underwent csPCNL.
- Correlation analysis and multivariate regression were used to assess patient demographics, stone characteristics, and procedural parameters against FST and RD.
Main Results:
- Body mass index (BMI), operative time, success rate, complications, stone number, and tract number were significantly associated with FST and RD.
- Multivariate analysis identified BMI, tract number, and success rate as independent predictors of FST and RD.
Conclusions:
- BMI, success rate, and tract number are key predictors of FST and RD in csPCNL.
- Identifying these predictors enables surgeons to better plan procedures and reduce radiation risks for patients.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
