Ureterocele - Overview

Definición:

Es una inflamación en el fondo de uno de los conductos (uréteres) que trasportan la orina desde el riñón hasta la vejiga. El área inflamada puede obstruir el flujo de orina.

Un ureterocele es un defecto congénito.

Causas, incidencia y factores de riesgo:

Un ureterocele ocurre en la parte inferior del uréter, donde el conducto ingresa en la vejiga. El área inflamada impide que la orina pase libremente a la vejiga; ésta se acumula en el uréter y estira las paredes, y finalmente estalla como un globo con agua.

Un ureterocele también puede provocar que la orina se devuelva de la vejiga al riñón, lo cual se denomina reflujo.

Los ureteroceles se presentan en aproximadamente 1 de cada 500 a 1 de cada 4,000 personas, y las personas de raza blanca son las más propensas a resultar afectadas. Este problema es igualmente común en ambos uréteres.
