Pyeloureteritis cystica: case report.

TL;DRAbstract

Pyeloureteritis cystica, characterized by multiple bubbly filling defects on urography and caused by inflammatory stimuli, is a rare disorder of the ureter. It commonly affects older people. Diagnosis is established by radiological studies. Antibiotics should be given if urinary tract infection is present. Up to now, no other specific treatment can be used to cure this disorder. We report a case of pyeloureteritis cystica associated with urinary tract infection and a ureteral stone in a young woman who presented with hematuria and bilateral flank pain. The pyeloureteritis cystica had a bead-like appearance on intravenous pyelogram and retrograde pyelogram as well as in magnetic resonance urography. The diagnosis and treatment of this disorder are discussed. Magnetic resonance urography can provide high-resolution of coronal images of the entire urinary tract without the use of contrast agents or ionizing radiation. However, the cost of the procedure is a major concern.
