Pyeloplasty: A procedure to remove blockage in the ureter


What is pyeloplasty?

No name
No state given


Pyeloplasty is a surgical procedure to remove a blockage in the tube (ureter) that carries urine from the kidney to the bladder due to a narrowing of the tube where it attaches to the kidney (ureteropelvic junction). This narrowing is usually present at birth (congenital). Rarely, it's caused by scarring, such as due to kidney stones or prior surgery. If the tube remains blocked, the kidney could stop working.

In pyeloplasty, the narrowed part of the ureter is removed (excised) and the ureter is reconnected to the kidney. A stent is placed to allow healing and drainage of urine from the kidney. Less-invasive procedures also are available for removing a blockage. These include:

  • Percutaneous method — the obstruction is corrected via a small incision in the side
  • Endoscopic method — the obstruction is removed via a small instrument inserted through the ureter
