Percutaneous Nephrolithotomy in Complex Renal Stones Evaluation of Single Step Amplatz versus Balloon Dilatation

Abstract

enal stones remain one of the most common urologic problems. Percutaneous Nephrolithotomy is the optimal treatment for complex renal stone. The goal of percutaneous nephrolithotomy (PCNL) is to ensure complete stone clearance with minimal morbidity. The technique of PCNL has developed over several years. The access tract can be dilated using a balloon dilator (BD) or a single-step Amplatz dilator. In the current trial we aimed to evaluate the efficacy of Percutaneous Nephrolithotomy as a primary modality of treatment for complex renal stones, moreover the feasibility and safety of single step dilatation using Amplatz dilator versus Balloon dilatation in the Percutaneous Nephrolithotomy access.
