DJ Stenting Surgery

What is a DJ Stent?

DJ stent is short for ‘Double J stent’. This is a small tube that is placed in the body from the kidney to the urinary bladder. This is kept for around 6 weeks. The lower portion is in the urinary bladder and is shaped as ‘J’ while the upper portion is like a mirror image. The shape helps in retaining the stent in the body.

What does the DJ stent do?

  • The ureter will remain open all the time.
  • It has multiple holes and even if there is a block in the path urine can travel through these holes and prevent back pressure changes and kidney destruction.
  • It prevents narrowing or strictures during the healing process. If there is obstruction or injury due to the stone the healing process would narrow down the tube.
  • This will help the kidney to push the stone. The DJ is referred to as foreign substance and the body will push it which makes it easier and this will help the stone to come out.
  • From the kidney, it will flush the stone. When the person moves or runs it creates movement in the kidney which makes the stone come out easily.
