Pyeloplasty (2126)

Key points below

What is a Pyeloplasty?

The ureter is a tube that goes from one of the kidneys to the bladder. Pyeloplasty is a surgery to remove a blocked section of the ureter.  The blockage is often a narrowing right where the ureter joins the kidney.

What do I need to know before my child’s surgery?

A nurse will call you 1 to 3 days before your child’s surgery.  The nurse will go over instructions that need to be followed before surgery.  The nurse will also tell you when your child has to stop eating and drinking.  It is very important to follow these instructions.   Surgery will be canceled if they are not followed. This is for your child’s health.

How is surgery done?

Your child will have general anesthesia to help them sleep in surgery.  A cut (incision) will be made in your child’s side. The blocked section will be removed. Alternatively, the surgery may be performed via several small cuts (“keyhole” incisions.) Your child’s surgeon will discuss the surgery with you in more detail.

Normally, your child will be in the hospital typically not more than 3 days, but may be discharged earlier if you and the team feel this is safe for your child. A tube (called a stent) may be put near the incision. The tube will drain urine away so the ureter has time to heal. The tube will be removed 6 to10 weeks later in the operating room.

How do I care for my child after the procedure?

Your child may not be hungry for the first 1 to 2 days after surgery.  Your child may feel nauseous.  The nurses and doctors will keep a close watch on this.  Once your child is hungry and passing gas, solid foods can be offered.

After surgery, you may hold your child.  Most young children find this very comforting.  Do not worry, as you will not hurt the wound.  Because there is an IV and often tubes and wires, the nurses will help you.  

The nurse will help older children sit in a chair and advance to walking. . 
Older children should avoid heavy play or sports after surgery. Their surgeon will tell you when they can start normal activities and sports.
