Background: Stag horn calculi may cause irreversible renal damage. Percutaneous nephrolithotomy is a minimally invasive surgical therapy than can be useful for these calculi. Aim: To report the experience with percutaneous nephrolithotomy for stag horn calculi. Material and Methods: Retrospective analysis of medical records of patients with stag horn calculi treated with percutaneous nephrolithotomy alone or associated to extracorporeal lithotripsy. All patients were treated with a rigid nephroscope, with one or more accesses during one or more sessions. Results: Twenty two women and 20 men aged 11 to 74 years were treated. One patient had only one kidney and one calculus was located in a horse shoe shaped kidney. The calculus was located in the right side in 27 patients and in the left side in 15. A unique access was used in 33 cases (79%), two accesses in nine (21%) and three accesses in three patients (7%). Nine patients had a residual lithiasis that required extracorporeal lithotripsy and one required an ureteroscopy. In 40 patients (95%), the complete removal of the calculus and its fragments was achieved. No patient died or lost the affected kidney. Conclusions: Percutaneous nephrolithotomy is a safe and effective minimally invasive surgical treatment for stag horn calculi.
