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.
