A Case of Pure Matrix Ureteral Stone: A rare type of urinary that may be overlooked.

Matrix stones are a rare form of urinary with a low mineral content. We report a 63-year-old female patient who presented to the Sohar Hospital, Sohar, Oman, in 2018 with unexplained left flank pain and constipation. She had a history of chronic renal failure (CRF) and had previously undergone haemodialysis (HD).
