Percutaneous nephrostomy and JJ stent

A percutaneous nephrostomy or JJ stent might be used if cancer is blocking the tubes that take urine from the kidney to the bladder.

In some people, the tubes that connect the kidneys to the bladder (ureters) may get blocked by the prostate cancer. If this happens, you may be offered one of the following types of surgery:

  • Percutaneous nephrostomy – The doctor puts a tube into the kidney that goes into a bag that sits outside on the skin. Urine can then drain into the bag.
  • JJ stent – This is a fine tube that is put into the ureter. The JJ stent opens up the ureter so urine can flow freely through it.

Your doctor or specialist nurse can give you more information about these types of surgery.
