Abstract
Percutaneous nephrolithotomy (PCNL) remains the treatment of choice for staghorn renal calculi. Many reports suggest that laparoscopy can be an alternative treatment for large renal stones. We wished to evaluate the role and feasibility of laparoscopic extended pyelolithotomy (REP) for treatment of staghorn calculi. Thirteen patients underwent REP for treatment of staghorn calculi over a 12-day period. Twelve patients had partial staghorn stones and one had a complete staghorn stone. All patients had pre-operative and post-operative imaging including KUB and computed tomography. All procedures were completed robotically without conversion to laparoscopy or open surgery. Mean operative time was 158 min and mean robotic console time was 108 min. Complete stone removal was accomplished in all patients except the one with a complete staghorn calculus. Estimated blood loss was 100 cc, and no patient required post-operative transfusion. REP is an effective treatment alternative to PCNL in some patients with staghorn calculi. However, patients with complete staghorn stones are not suitable candidates for this particular technique.
