Laparoscopic anatrophic nephrolithotomy for management of staghorn renal calculi

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.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.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.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.
