[Cystic dystrophy of the urinary excretory mucosa. An unusual cause of recurring urinary tract infection in pregnancy].

Cystic pyeloureteritis is an uncommon anatomo-radiological phenomenon which occurs following injuries to the mucosa often accompanied by inflammatory changes. Treatment is not well defined and the prognosis for renal function is problematic. The authors report one case that occurred after delivery. The literature has been reviewed and the case described has been discussed. Attention has been focused on infections of the urinary tract in pregnancy and the long-term prognosis. This appears to be worse when it is associated with the not-uncommon abnormalities of the urinary tract. These should be looked for systematically using ultrasound and intravenous pyelogram techniques.
