    my daughter has mild left kidney hydronephrosis

    I just found out that my daughter has mild left kidney hydronephrosis and was wondering if someone can help me understand what it is
    john-skpt responded:
    Hydronephrosis simply indicates a build up of fluid, usually urine, inside the spaces of the kidney that normally drain out to the ureter and eventually to the bladder.

    You don't mention her age, but this condition is very common in neonates and infants, since the urinary structures are not fully developed. These cases often, but not always, resolve spontaneously.

    In adults, the cause is often an obstruction to the free-flow of urine: a stone, a narrowing of the ureter, inflammation or scarring from an infection.

    There are a lot of treatment options, depending on the exact cause.

    Im sorry my daughter is 5 and I just found out that she had it and am very worried
    john-skpt replied to mikkimikey13's response:
    The age helps a bit, but every case is different. If you can, locate a pediatric urologist; things with kids are just very different than with adults.

    Depending on whether any pain is present, the rate of urinary infections, etc., those things will affect whether the docs advise treating soon or waiting a few years. As mentioned, a lot of cases just sort themselves out as the body grows and the organs take on their final form and position.

    And some additional tests might indicate whether there is some structural problem with the ureter-bladder path that might benefit from surgery or other intervention.

    It's just impossible to make any general assumptions. It is, however, probably safe to assume that there is not yet any severe permanent damage to the kidney, as long as the blood test numbers look good, and urinary infections are not very frequent or hard to treat.

    Talk to the doc in detail for more specifics, since the local doc has all the relevant test results.
