The advent of new technologies has paved the way for the refinement of endoscopic techniques for the treatment of pelvocalyceal stones. Percutaneous nephrolithotomy (PCNL) is a safe and minimally invasive approach when compared to open surgery for patients with pelvo-caly-ceal stones. During the past decade, the indications for PCNL have been better defined, and there is a unanimous trend towards minimally invasive procedures for the treatment of such calculi.

Mastering of percutaneous techniques is deemed necessary for the safe and effective management of stone disease. Stones varying in size, from small pelvic stones to complete stag-horn calculi, can be treated successfully with PCNL [1-4]. The main goal in the management of patients with stone disease, from the perspective of patient satisfaction, is how much stone burden is left behind and at what cost. Therefore the patient should be well informed about the alternative treatment regimes and should be offered the optimal therapeutic treatment.
