[Classification and treatment of ureteroceles in the adult]. / Classification et traitement des urétérocèles de l'adulte.

ABSTRACT

Ureterocele or congenital pseudocystic dilatation of the terminal portion of the ureter due to persistence of Chwalla's membrane is frequent in female adults (17-35%) in its orthotopic form. It expands the short submucosal segment of the normally situated ureter and may be intravesical or extravesical. The diagnosis is primarily radiological based on intravenous urography (IVU) and endoscopy (urethrocystoscopy). Treatment depends on the site of the ureterocele, the clinical context, associated anomalies and especially the dimensions. Endoscopic treatment has numerous advantages and deserved to be more widely used.
