Standard lead aprons and thyroid shields do not protect the head, arms, and legs. The RADPAD® is a novel lead-free shield that can be positioned directly in the surgical field to block scatter radiation. The primary objective of this study was to assess the effectiveness and added protection of the RADPAD® compared to conventional lead. METHODS: To simulate a PCNL, a radiographic phantom patient and a mannequin surgeon were utilized (Figure 1a). Using a real-time dosimeter, radiation doses were measured in μSv at seven distinct anatomical locations on the surgeon: head, neck, chest, abdomen, pelvis, forearm, and leg. Three shielding devices were evaluated (Figure 1b): a conventional lead apron with a thyroid shield (LATS), a double-thickness RADPAD® (R2), and a triple-thickness RADPAD® (R3). The effectiveness of combining LATS with R2 or R3 was also examined and compared to baseline (no lead). Five trials of five seconds of fluoroscopy were conducted for each site and shielding combination. The Mann-Whitney U test was used to compare exposures with p<0.05 significant. RESULTS: LATS alone significantly reduced radiation exposure at all protected sites compared to baseline, reaching reductions>95% (p<0.05). There was no protection by LATS to the head, forearm, and leg of the surgeon. Use of R2 or R3 alone significantly reduced radiation at all tested sites (p<0.05) compared to baseline, except the legs. Compared to LATS alone, use of R2 or R3 significantly reduced radiation exposure to the head (up to 48%) and forearm (up to 84%; p<0.05). Combining LATS with R3 resulted in the greatest reduction in radiation, performing significantly better than LATS alone at the head, pelvis, and forearm (p<0.05). No single shielding device or combination significantly reduced radiation exposure to the legs. CONCLUSIONS: The LATS alone reduced radiation>95% at shielded sites, but provided no protection to the head, forearm, and leg. Addition of the RADPAD® to conventional LATS functions as an effective and novel strategy that reduces radiation exposure at all measured sites except the legs, and provides important protection to the head and arms of the surgeon without increasing the weight burden.
