[Cystic pyeloureteritis and infection. Presentation forms and review of the literature].
OBJECTIVE
To present three illustrative cases of pyeloureteritis cystica and review the literature.


METHODS
Three illustrative cases diagnosed at our department are described. Patient history, clinical features, diagnostic procedures and treatment are analyzed and the literature is reviewed.


RESULTS
Our patients had no specific symptoms. All three patients had urinary tract infection with pyeloureteral involvement, which was bilateral in two cases. One of these patients had a long-indwelling catheter.


CONCLUSIONS
Pyeloureteritis cystica is a benign and uncommon condition whose etiology is not well-known. It is generally associated with chronic infection and inflammation, and may be difficult to distinguish from other filling defects of the urinary tract. Due to its benign nature, treatment must always be conservative and close follow-up is recommended.
