Percutaneous nephrolithotomy operation in a patient with severe kyphosis due to ankylosing spondylitis Ankilozan spondilite bağli ciddi kifozu olan hastada perkütan nefrolitotomi operasyonu

Ankylosing spondylitis is a chronic inflammatory form of arthritis that affects the spinal joints. The skeletal deformity caused by this condition may hamper surgical procedures by causing difficulties in patient positioning. We present our technique of patient positioning for percutaneous nephrolithotomy in a patient with severe kyphosis and immobility of the cervical spine caused by ankylosing spondylitis.
