What is Pyeloplasty Surgery?
Pyeloplasty is a surgical procedure used to treat hydronephrosis, a condition where one or both kidneys become swollen due to a blockage or obstruction in the urinary system. This surgery helps remove the blockage, allowing urine to flow freely and preventing further kidney damage.
Pyeloplasty is usually performed when hydronephrosis is causing symptoms or has the potential to damage the kidneys. The goal of the surgery is to relieve the blockage, restore normal kidney function, and prevent long-term complications.
Why is Pyeloplasty Necessary?
Hydronephrosis in children can range from mild to severe. Most cases are mild and resolve on their own, but sometimes more serious cases require surgical intervention. Pyeloplasty is recommended if the child has a persistent obstruction that may lead to:
- Kidney damage: When urine cannot drain properly, it can put pressure on the kidney, leading to a decline in kidney function over time.
- Recurring urinary tract infections (UTIs): A blockage in the urinary system can increase the risk of UTIs, which can further harm the kidneys.
- Pain: Some children with hydronephrosis experience pain in the abdomen or back due to the pressure buildup in the kidneys.
- High blood pressure: Long-term kidney problems can lead to elevated blood pressure if left untreated.
By performing pyeloplasty, the surgeon can remove the blockage and restore normal urine flow, helping to protect the kidneys from damage and relieve symptoms.
How is Pyeloplasty Performed?
Pyeloplasty is performed under general anaesthetic, meaning your child will be asleep throughout the surgery. There are two primary surgical techniques used for pyeloplasty:
Minimally Invasive Pyeloplasty (Laparoscopic or Robotic): In some cases, pyeloplasty can be performed using laparoscopic or robotic techniques. This involves making several small incisions in the abdomen and using a camera and specialised instruments to perform the surgery.
Open Pyeloplasty: A small incision is made in the child’s back or side of the abdomen to access the kidney and ureter.
The surgeon removes the blockage or damaged tissue at the pelviureteric junction (PUJ) and reattaches the ureter to the kidney to restore proper urine flow.
The choice of surgical method depends on the severity of the obstruction, your child’s anatomy, and the surgeon’s recommendation.
How Long Does the Operation Take?
Pyeloplasty typically takes between 1 and 2 hours to complete, depending on the technique and anatomy.
After the surgery, your child will spend some time in the recovery room as they wake up from the anaesthesia. You will be notified when they are ready for you to see them, and they will remain under observation for several hours. Most children can go home within 24-48 hours after the procedure, though in some cases, a longer hospital stay may be required for monitoring.
Risks and Complications of Pyeloplasty
While pyeloplasty is generally a safe procedure, as with any surgery, there are some risks and potential complications, including:
- Infection: This is uncommon but can occur after surgery. It may present as redness, swelling, or discharge around the incision site.
- Bleeding or Bruising: Minor bruising and swelling around the incision are normal and usually resolve on their own.
- Recurrence of Blockage: In rare cases, the ureter may become blocked again, requiring further surgery.
- Urine Leak (Fistula): Occasionally, a small leak may form at the site where the ureter was reattached to the kidney, which may need additional treatment.
Your surgeon will discuss these risks with you before the surgery and ensure that you know what signs to watch for during recovery.
What to Expect After Pyeloplasty Surgery
Pain Relief
Your child will receive pain relief during and after the surgery to keep them comfortable. Over-the-counter medications such as paracetamol (Panadol) or ibuprofen (Nurofen) may be used for pain relief at home. If your child has any allergies or intolerances to medication, be sure to inform the anaesthetist and surgeon.
Wound Care
If your child had open pyeloplasty, there will be a small incision in the side or abdomen. The wound will be covered with a waterproof dressing, which can be removed after about a week. If your child had minimally invasive pyeloplasty, they will have a few small incision sites, also covered with waterproof dressings.
Initially after the operation, your child’s urine may be blood-stained, but this should clear after a few days.
Urinary Catheter
In some cases, a urinary catheter may be placed during surgery to ensure proper drainage of urine from the kidney. These are temporary and will be removed during a follow-up visit. You will be provided with instructions for how to care for the catheter at home.
When Can My Child Return to Normal Activities?
Your child will receive good pain relief during the operation, and this should last for a few hours afterward. Once at home, you may need to give your child paracetamol (e.g., Panadol) and possibly ibuprofen (e.g., Nurofen) for a few days. Please let your surgeon and anaesthetist know if your child has intolerances or allergies to particular medications.
It’s also helpful to distract your child and keep their mind off the surgery site. Activities like reading, playing board games, or other quiet, engaging tasks can help ease discomfort and take their mind off the area.
Long-Term Prognosis and Follow-up After Pyeloplasty
The long-term outlook for children after pyeloplasty is generally excellent. Once the blockage is removed, most children experience normal kidney function and a resolution of their symptoms. The risk of future complications, such as kidney damage or urinary infections, is significantly reduced, and regular follow-up visits will help ensure that your child’s kidneys continue to function well.
When to Seek Medical Attention After Surgery
It’s important to keep a close eye on your child’s recovery and seek medical attention if they experience any of the following:
- Fever above 38.2°C.
- Severe pain or pain that does not improve with medication.
- Redness, swelling, or discharge from the incision site.
If any of these symptoms occur, contact your family doctor or call your surgeon for further advice.
