Background: Management of staghorn renal stones is still challenging. We present our experience with laparoscopic anatrophic nephrolithotomy as an alternative option for management of staghorn renal calculi. Patients and Methods: Twenty-four patients with staghorn renal calculi underwent 25 laparoscopic anatrophic nephrolithtomy procedures. Characteristics of patients and stones along with perioperative features such as operation time, transfusion, ischemic time, hospitalization, stone-free rate, and biochemical data were recorded prospectively. We applied the one-layer knotless technique for renorrhaphy repair. Results: The mean age of the patients was 55.1±10.9 years (range, 28-74 years). Eleven (44%) operations were done on the right side, and 14 (56%) were done on the left side. Complete and partial staghorn stones existed in 17 (68%) and 8 (32%) renal units, respectively. The mean stone size was 61.5±11.5 mm. Ischemic time was 30.4±7.55 minutes. The stone-free rate was 88% on discharge and 92% after one session of extracorporeal shockwave lithotripsy. Conclusions: Although percutaneous nephrolithotomy is the standard of care for treatment of staghorn stone, laparoscopic anatrophic nephrolithotomy seems to be a safe and feasible option in select patients.
