Percutaneous nephrolithotomy (PCNL) has replaced open pyelolithotomy as the procedure of choice for treating large-burden renal stone disease, especially staghorn calculi. Although it is a minimally invasive procedure, it involves transgressing the renal parenchyma and is thus associated with its unique set of complications. The evolution of laparoscopic pyelolithotomy and robotic assistance has provided an opportunity to the surgeon to revisit pyelolithotomy in a minimally invasive manner following the age-old principles of the era of open renal surgery. We report the feasibility and our experience with this technique in three cases of partial staghorn calculus with intra-renal pelvis.
