This study is designed to demonstrate the efficacy of Instadose™ for the measurement of radiation exposure during percutaneous nephrolithotomy (PNL) and define the factors that affect the amount of radiation exposed. METHODS Two experienced surgeons wore Instadose™ on the outer part of the lead aprons during the PNL procedures performed between December 2013 and July 2014. Patient demographics and stone characteristics were noted. Factors affecting radiation dose were determined. Fluoroscopic screening time was compared with the amount of radiation in order to validate the measurements of Instadose™. RESULTS Overall 51 patients with a mean age of 43.41±18.58 (range 1-75) years were enrolled. Male to female ratio was (35/16). The amount of radiation was greater than 0.01mSv in 19 (37.25%) cases. Stone location (p=0.380), stone size (p=0.565), dilation type (p=0.584), dilation size (p=0.891) and access number (p=0.268) were not associated with increased radiation exposure. Instadose™ measurements were correlated with fluoroscopic screening time (r=0.519, p=0.001). CONCLUSIONS Instadose™ is a useful tool for the measurement of radiation exposure during PNL. The advantage of measuring the amount of radiation exposure after each PNL operation may aid urologists take appropriate precautions to minimize the risk of radiation related complications. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e347 Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information Emrah Yuruk More articles by this author Gokhan Gureser More articles by this author Murat Tuken More articles by this author Kasim Ertas More articles by this author Ege Can Serefoglu More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
