Percutaneous nephrolithotomy with and without retrograde pyelography: preliminary results of a randomized controlled trial.

Introduction: Since the introduction of percutaneous nephrolithotomy (PNL), many modifications to entering the pyelocalyceal system have been made. One alternative is to insert a needle pointed to an opaque stone as a landmark. The aim of this study was to compare the outcomes of managing kidney calculi by PNL with and without retrograde pyelography.
