[Empyema of the ureteral stump with multiple stones after nephrectomy]

A 64-year-old woman, who had undergone right nephrectomy because of right incomplete double pyeloureter and dysplastic kidney with a ureteral stone at the age of 25, presented with a chief complaint of repeated urinary tract infection associated with right lower abdominal pain. A diagnosis of empyema of the ureteral stump with multiple stones was made based on X-ray findings and cystoscopy. In December 1999, the right residual ureter and ureteral stones were removed. Histopathologically, non-specific inflammatory change and fibrosis of the wall were observed. The ureter including the stones should have been resected at the previous nephrectomy.
