Percutaneous Nephrolithotomy Performed on the Kidney Stone in a Patient With Ankylosing Spondylitis: A Case Study.

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.
