Abstract:
Synovitis, Acne, Pustulosis, Hyperostosis, Osteitis (SAPHO) syndrome shows varied pathological symptoms. This is the first report of hydronephrosis due to the mechanical compression of bilateral ureters as a result of SAPHO syndrome. From our experience, MRI is the most useful imaging examination to check the upper urinary tract in SAPHO syndrome.
