Condition

PUJ obstruction and hydronephrosis

Also known as: Blocked kidney outlet, swollen kidney

Hydronephrosis means a kidney is swollen because urine cannot drain from it normally. One common cause is PUJ obstruction, a narrowing where the kidney joins the ureter, which can be seen in children and adults. Other causes include stones and narrowing of the ureter.

Common symptoms

  • Pain in the side or back, sometimes after drinking a lot of fluid
  • Urinary infections
  • Blood in the urine
  • No symptoms, when found on a routine or antenatal scan

When not to wait: Go to an emergency department at once for severe pain with fever or chills, or if you cannot pass urine. These can be signs of an infection or blockage that needs urgent treatment.

Tests that may be needed

  • Ultrasound
  • Renal scan (DTPA or EC), which shows drainage and each kidney’s function
  • CT urogram, in selected cases

Cost, insurance and government schemes

Cost depends on the procedure and your hospital stay. See how estimates, insurance and schemes work.

Frequently asked questions

Does a swollen kidney always need surgery?

No. Some cases, especially in babies, are watched with repeat scans. Surgery is considered when the kidney’s drainage or function is affected, or when there is pain or infection.
