A 34-year-old male came to us with congenital spina bifida, vesicoureteral reflux and scoliosis. He had been on hemodialysis for chronic renal failure caused by reflux nephropathy since the age of 23 years. At the age of 24, he received bilateral nephrectomy and underwent living renal transplantation from his mother. Hemodialysis was started again at the age of 26, because the renal graft was not functioning. At the age of 34, the patient developed a fever that persisted for a few days. He received antibiotic medication from his physician, but since his condition did not improve he was refered to our hospital. A computed tomography scan examination revealed abscess formation in the left retroperitoneum. Magnetic resonance imaging findings also showed the abscess in the left retroperitoneum. The patient was diagnosed with empyema of the residual ureter and underwent a left ureterectomy procedure.

Matrix stones are a rare form of urinary calculi 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). Non-contrast computed tomography (CT) did not show any renal or urinary stones. However, a left-sided ureteroscopy revealed a yellow-coloured stone that was soft in consistency occupying the proximal 5 cm section of the ureter. Many attempts at forceps extraction were required for complete clearance. A global quantitative composition analysis revealed the extracted stone to be composed entirely of protein-matrix material. Matrix stones require a high index of suspicion as they are sometimes radiolucent and cannot be visualised on CT scans. Risk factors include being female and a history of urinary tract infections, CRF and HD.

Malignant neoplasm arising from ileal ureter used for ureteral reconstructive surgery is an exceedingly rare event. Ureteroileoplasty was being performed since the beginning of the last century, but it was described more extensively in literature during the 1950s.1,2 Recurrent urinary infections, chronic renal failure, urolithiasis, anastomotic stricture, metabolic acidosis, and chronic dilation of the graft had been described as late complications of ureteroileoplasty.3,4 Herein, we describe history, imaging and pathologic findings of a small bowel adenocarcinoma arising from ileal ureter in a woman of 78-year-old, subjected to ureteroileoplasty about 40 years earlier.
