Causas:

La uropatía obstructiva unilateral es causada con más frecuencia por un cálculo renal, aunque cualquier lesión u otra afección pueden causar el trastorno.

Cuando se bloquea el flujo de orina, ésta se represa en los riñones y lleva a que se presente hinchazón renal, también llamadahidronefrosis.

Uno tiene mayor riesgo de padecer uropatía obstructiva unilateral si tiene cálculos y tumores ureterales, cálculos renales y tumores en estructuras corporales cercanas como el útero y el cuello uterino.

La uropatía obstructiva unilateral aguda se presenta en 1 de cada 1,000 personas.
