Abstract: (386 Views)
Background and Objective: To achieve the least reasonably achievable’ dose of radiation, we have herein introduced a new technique for performing Percutaneous nephrolithotomy (PCNL) under fluoroscopic guidance, named “Low-Fluoro PCNL” (LFPCNL).
Materials and Methods: PCNL was performed using a standard technique. Modifications in LFPCNL were as follows: Alken guide was replaced on the guidewire and passed into the selected without fluoroscopy.
Thereafter, the 30F Amplatz sheath was passed over the dilator without fluoroscopy. To ensure the correct position of the Amplatz sheath, intrarenal saline fluid injection was performed through the ureteral catheter.
Results: LFPCNL was performed in 13 patients (8 males, 5 females) with a mean age of 47.2±15.4 years. The mean fluoroscopy time and mean radiation dose scores were 66.3±40.0 seconds and 24±20 mGy, respectively. No complications occurred in this series of patients.
Conclusion: The present study has introduced the LFPCNL technique as a new, feasible, and safe fluoroscopic-guided PCNL that reduces radiation time. This study had a case series setting and was performed as a feasibility study. This issue is the main limitation of our research; therefore, it is highly recommended to assess the efficacy of our technique in a prospective comparative study with a large sample size
