What You Need to Know About Hydronephrosis


Hydronephrosis is a condition in which one or both of the kidneys become swollen due to an accumulation of urine. It is often caused by a blockage in the urinary tract that prevents urine from flowing freely. In some cases, hydronephrosis can cause kidney damage, particularly if it goes undiagnosed and untreated. Here's what you need to know about this condition.

Causes of Hydronephrosis

Hydronephrosis can result from a variety of causes, including kidney stones, tumors, birth defects, or an enlarged prostate. It is commonly seen in infants as part of a condition known as antenatal hydronephrosis. This occurs when the fetal kidneys fail to fully develop, causing urine to back up in the kidney and cause swelling. Another possible cause is vesicoureteral reflux, a condition in which urine flows backward from the bladder into the ureters, resulting in an accumulation of fluid in the kidney.

Symptoms and Diagnosis

The most common symptom of hydronephrosis is pain in the lower back and abdomen, but other symptoms can include:

  • nausea,

  • vomiting,

  • blood in the urine,

  • difficulty urinating,

  • fever, and fatigue.


If left untreated, the condition can cause permanent damage to the kidneys.


Diagnostic tests typically include an ultrasound or CT scan to evaluate kidney structure, as well as lab tests such as a urinalysis or creatinine test to measure levels of waste products in the blood. Additionally, your doctor may order an intravenous pyelogram (IVP) or a cystoscopy to further assess kidney function and diagnose any potential underlying causes of your symptoms.

Complications Associated With Hydronephrosis

In addition to pain and discomfort associated with hydronephrosis itself, there are several potential complications that may arise from this condition including hypertension (high blood pressure), kidney infection due to accumulation of bacteria-laden urine in the kidney(s), elevated levels of waste products in your bloodstream (azotemia), urinary tract obstruction due to scarring from inflammation or infection related to hydronephrosis ,and possible long-term renal failure if left untreated for too long .It’s important for anyone suffering from this condition seek professional support promptly in order diagnose it accurately and effectively manage its symptoms over time.


The goal of treatment is to relieve the pressure on the affected kidney(s) and restore proper urinary flow. Depending on your specific case and diagnosis, treatment options may include antibiotics if an infection is present, medications to reduce swelling or pain associated with the condition, surgery to remove any blockages causing hydronephrosis, or dialysis if necessary. Additionally, there are certain lifestyle changes that you can make to help manage symptoms of hydronephrosis such as drinking plenty of fluids throughout the day and avoiding caffeine and alcohol consumption.

Some Prevention Tips

The best way to minimize the risk of developing hydronephrosis is to maintain a healthy lifestyle.  This includes eating foods rich in antioxidants, staying physically active, maintaining a healthy weight, drinking plenty of water throughout the day, urinating more frequently, and avoiding acidic foods and alcohol are all suggested preventative measures. Additionally, it's beneficial to be aware of any family history of hydronephrosis, since those with such a history have an increased likelihood of developing the condition. By following these suggestions and having regular check-ups with a medical professional, those at risk can significantly reduce their chances of developing hydronephrosis.

Taking Action Against Hydronephrosis

Hydronephrosis can be a difficult condition to live with, but there is hope. With the right treatment and lifestyle changes, you can manage your symptoms and reduce complications. Additionally, seeking professional advice from your healthcare provider and support from family and friends will help you to cope more effectively with this condition. Don’t let fear prevent you from taking action against hydronephrosis.  By taking positive action, you can reduce your risk of potential complications and enjoy a more healthy and pain-free life.
