Pyeloplasty

A pyeloplasty is an operation to repair a narrowing in the junction where the kidney joins the ureter.

The ureter is a tube that drains urine from the kidney to the bladder.

Narrowing of the pelvic ureteric junction can occur for many reasons. These include:

  • Injury
  • Trauma from surgery
  • Recurrent urinary tract infections
  • Or most commonly, it could have been present since birth.

You should have nothing to eat six hours before the operation, but can drink up to two hours to your operation.

The area around the surgical incision site may need to be shaved before the operation.

During the operation

The procedure involves an incision over the site of the affected kidney. The narrowing is then reconstructed.

A stent is inserted into the ureter to maintain the new wider channel. The stent will usually stay in place for several weeks and you will have to return to hospital to have it removed under local anaesthetic.

Occasionally, a nephrostomy tube is inserted directly into the kidney to drain off the urine and allow the kidney to recover after surgery. The nephrostomy tube is removed before you go home.

A urethral catheter is inserted and kept in place for 24 hours to monitor urine drained from the non-treated kidney.

A wound drain may also be inserted and kept in place until the drainage is less than 50 mls in 24 hours.

The procedure takes about 3 hours, and inpatient recovery period will take 3-5 days. Post discharge recovery is 4-6 weeks.
