Paediatric obstructive uropathy
OVERVIEW
Obstructive uropathy refers to a blockage in the urinary tract that obstructs the normal flow of urine from the kidneys through the ureters, bladder, and urethra, leading to urinary tract dysfunction and potential damage to the kidneys.
Obstructive uropathy can be caused by a variety of factors, including posterior urethral valves (PUV), vesico-ureteric junction obstruction or pelvi-ureteric junction obstruction (PUJO) in children. Other conditions, such as infections, or neurogenic bladder, can also lead to obstructive uropathy.

Symptoms of obstructive uropathy
The symptoms of obstructive uropathy can vary depending on the severity and location of the blockage. Some common symptoms include the following:
- Pain: Obstructive uropathy can cause pain in the lower abdomen, flank (sides), or back. The pain may be dull or sharp and may come and go.
- Difficulty urinating: You may experience difficulty urinating, such as a weak stream, dribbling, or feeling like you need to urinate frequently but can't.
- Urinary tract infections: Obstructive uropathy can increase your risk of developing urinary tract infections, which may cause symptoms such as a burning feeling during urination, frequent urination, and cloudy or strong-smelling urine.
- Swelling: Obstructive uropathy can cause swelling in the legs, feet, or other parts of the body. Swelling in the legs, feet, or other parts of the body can be caused by obstructive uropathy, as the kidneys are unable to filter fluids properly.
- Nausea and vomiting: In severe cases, obstructive uropathy may lead to symptoms such as nausea, vomiting, and decreased appetite.
- Blood in urine: Obstructive uropathy may cause blood to appear in the urine, which can be a sign of a serious underlying condition.
It is important to see a doctor if your child experiences any of these symptoms, as untreated obstructive uropathy can lead to kidney damage and other complications.
Treatment
The treatment of obstructive uropathy depends on the underlying cause and severity of the condition. Some common treatments include the following:
- Medications: If the obstruction is caused by an infection or inflammation, antibiotics or anti-inflammatory drugs may be prescribed to relieve symptoms and treat the underlying condition.
- Surgery: In some cases, surgery may be necessary to remove the blockage. This can involve removing the tissue causing the obstruction.
- Urinary catheter: A urinary catheter may be temporarily placed to relieve the obstruction and allow urine to flow properly.
- Stents: A flexible and small tube called a stent can be inserted into the ureter to facilitate urine flow and maintain its openness. Stents can be utilised for either short-term or long-term treatment.
- Nephrostomy: If the blockage is severe and cannot be treated with other methods, a nephrostomy may be performed. This involves creating a small opening in the back to allow a tube to be inserted directly into the kidney to drain urine.
Seeking medical attention for a proper diagnosis and treatment of obstructive uropathy is crucial since untreated obstruction can cause severe complications such as kidney damage and kidney failure.
