[Cystic ureteritis. Presentation of a new case and review of the most recent national literature].

We report on a patient with this uncommon condition that presented without hematuria and in association with a rare abdominal and thoracic malformation known as situs inversus. A review of the literature focussing on recently reported cases in the Spanish literature revealed it to be a disease of unknown etiology whose pathogenesis is not well-established, clinical features unspecific, without treatment for the underlying cause, and is a radiologic diagnostic difficulty requiring a differential diagnosis from other filling defects in the urothelium.
