Pyeloplasty is a surgery to repair the kidney. Specifically, it repairs a part of the kidney called the renal pelvis. The renal pelvis is a funnel-like structure. It connects the kidney to a tube called the ureter. This tube carries urine to the bladder.
Reasons for Procedure
Pyeloplasty is done if a blockage is found at the renal pelvis. This blockage prevents the urine from passing and makes the kidney swell.
Possible Complications TOP
Complications are rare, but no procedure is completely free of risk. If you are planning to have a pyeloplasty, you or your child's doctor will review a list of possible complications which may include:
What to Expect TOP
Prior to Procedure
A physical exam will be done before surgery. The doctor may also require blood and urine tests.
The bowels will also need to be cleaned. Your diet will be limited to clear liquids the night before. Do not eat or drink on the morning of the surgery.
Talk to the doctor about medications. You may be asked to stop taking some medications up to one week before the procedure, like:
General anesthesia will be given. You will be asleep.
Description of Procedure
Pyeloplasty may be done using open surgery or laparoscopic surgery. A catheter will be placed to allow urine to drain.
During open surgery, an incision will be made in your side. The renal pelvis will be reconstructed. The blocked section will also be removed. The remaining healthy sections of will be re-attached. The incision in the skin will then be closed with stitches.
Laparoscopic surgery only requires a few small incisions. Special tools will be passed through these incisions to complete the surgery. The repair steps are the same as the open procedure above.
In some surgeries, a temporary tube may be placed in the ureter. This will allow urine to pass while the area heals.
How Long Will It Take?
About 2-3 hours
How Much Will It Hurt?
Anesthesia will block pain during the surgery. You may have some pain after the surgery. Your doctor will recommend medication to help you manage the pain.
Average Hospital Stay
The usual hospital stay is 2-3 days. Your doctor may choose to keep you longer if complications arise. The stay may be shorter if you had a laparoscopic surgery.
At the Hospital
You will receive medication to ease discomfort. You may have some discomfort the first few times you urinate after surgery. It is also common to feel a frequent need to urinate. It will pass.
