title: Calcification of bilateral ureters: a novel association with systemic lupus erythematosus.
abstract: A 16-year-old female patient with systemic lupus erythematosus (SLE) presented with abdominal pain and oliguria, after one month of hospital treatment with methylprednisolone and cyclophosphamide. Computed tomography of the abdomen revealed the calcification of bilateral superior segmental ureteral wall. Computed tomography urography revealed stenosis of bilateral ureters. This calcification may be associated with lupus-induced inflammatory reaction of ureteral endomembrane. By receiving the ureteral catheters, her abdominal pain and oliguria had been completely resolved. After discharge, she underwent the surgery of cutaneous ureterostomy in the local hospital. During two years follow-up, her condition is stable without any symptom of the urinary system.
