Why kidney gets swollen?

Kidney swelling, known medically as hydronephrosis, can indeed be a cause for concern and warrants attention to determine the underlying issue and its seriousness. The swelling of kidneys commonly occurs due to a blockage in the urinary tract. This could be caused by kidney stones, which can obstruct the flow of urine, leading to a backflow that causes the kidneys to swell. Other potential causes might include urinary tract infections (UTIs), where the inflammation and infection could lead to blockage and swelling. Additionally, conditions like kidney infections (pyelonephritis) and certain structural abnormalities in the urinary tract can also result in swelling of the kidneys. Another important aspect to consider is the possibility of a condition known as vesicoureteral reflux, where urine flows backward from the bladder into the kidneys. Less commonly, external compression of the urinary tract from tumors or enlargement of surrounding organs, like the prostate in men, might also lead to hydronephrosis.

Since you’ve mentioned fluid retention and abdominal swelling, it’s crucial to discuss whether you’re experiencing any related symptoms such as changes in urination (frequency, color, or pain), fever, nausea, or weight changes. These details can provide your healthcare provider with valuable information for a more precise diagnosis. Considering the symptoms you described, it’s advisable to follow up with your doctor about the test results you’ve had, and whether an ultrasound, CT scan, or MRI could provide further insights into the cause of the kidney swelling. Your doctor may also suggest additional urine or blood tests to evaluate kidney function and rule out infections. In terms of self-care, ensuring adequate hydration with plenty of water, monitoring any changes in symptoms, and avoiding any over-the-counter medications that could potentially affect kidney function, such as NSAIDs, could be beneficial until you receive further guidance.

Since your symptoms may indicate several potential underlying conditions, it’s crucial to seek medical attention promptly if you notice any worsening of symptoms, such as increased pain or fever, as these could indicate a more acute problem requiring urgent intervention. Clear communication with your healthcare provider about your concerns and symptoms is key to ensuring you receive timely and appropriate care.
