A 68-year-old man with serious cervical kyphosis and dorsolumbar scoliosis due to ankylosing spondylitis was admitted with a stone 17 mm in size in left kidney lower calyx. A percutaneous nephrolithotomy operation was decided considering the size and location of stone and the anatomical deformities of patient. The kidney was accessed through monoplaner triangulation method by giving a special position of the patient's spinal deformity and stone was successfully removed. Percutaneous nephrolithotomy is a feasible method in ankylosing spondylitis patients in case that the right position is achieved. Each patient should be assessed individually deciding on treatment methods. (C) 2015 The Authors. Published by Elsevier Inc. This is an open access article under the CC BY-NC-ND license
