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  

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

  • Bleeding
  • Infection
  • Hernia near the surgical site
  • Damage to tissues or organs
  • Persistent leakage of urine
  • Blockage of the ureter

Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:


What to Expect  

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.


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 ureter 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.

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 prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.

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.

Post-procedure Care  

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 a
