Abstract :

Introduction & Objective: To perform an economic single step renal dilation during percutaneous nephrolithotomy (PCNL) using directly the 30F amplatz dilator over the central Alkan dilator in a trial to reduce the operative time and radiation exposure during renal dilation while avoiding exchange of dilators which may increase risk of blood loss. Materials and methods: Prospective randomized study including 49 patients divided into 2 arms, the first had renal dilation before PCNL using the standard metallic telescopic dilators(Alkan�??s), the second arm had renal dilation using directly the 30F Amplatz dilator over the central Alkan. Operative time with x-ray exposure was calculated. Procedure outcome in terms of complications, stone free rates, and hospital stay was evaluated. Statistical analysis was done using the SPSS program. Results: Proper tract dilation was obtained in all cases. Operative time and X-ray exposure was shorter in patients undergoing single step dilation (P<0.05). Perioperative complications according to Clavien grading system occurred in 17(34%) patients yet no statistical difference in both arms. Stone free rates were comparable in all study group. Conclusion: Single step renal dilation when performing PCNL is feasible, with shorter Operative time and X-ray exposure. It shows outcomes comparable to standard metallic telescopic dilation.
