Pyeloplasty

The ureter is the tube that carries urine from the kidney to the bladder. If urine can’t flow through the ureter, it builds up in the kidney. This may cause symptoms such as pain, fever, and vomiting. It can also cause serious health problems such as infection or kidney damage. Urine flow through the ureter can be blocked by a narrowing of the ureter walls (stricture). A blood vessel that presses on the ureter can also cause it. Pyeloplasty is surgery to unblock the ureter and allow urine to flow again. Read on to learn more about the surgery and what to expect.

Preparing for Surgery

Prepare for the surgery as you have been told. In addition:

  • Tell your doctor about all medications you take. This includes over-the-counter medications, herbs, and supplements. You may need to stop taking some or all of them before surgery.

  • Do not eat or drink during the 8 hours before your surgery. This includes water, gum, and mints.

  • You may be given a special liquid or medication to take the day before the surgery. This is to make sure your colon is empty for the surgery.

Two Types of Surgery

The surgery may be done through several small incisions (laparoscopy). Or, it may be done through one larger incision (open surgery). Laparoscopy cannot be used in all cases. And surgery begun with laparoscopy sometimes must change to open surgery for safety reasons. You and your doctor will discuss your options.

  • For laparoscopy, the doctor makes 3-5 small incisions in the abdomen. The scope is put through one of the small incisions. The scope sends pictures from inside the abdomen to a video screen. Surgical tools are placed through the other incisions. The surgeon may use a technique called robotic laparoscopy. The robotic system gives a 3D view inside the body. It also assists the surgeon’s hand movements.

  • For open surgery, one larger incision is made in the side over the ribs. The doctor sees and works through this incision. Part of a rib may need to be removed so the doctor can reach the kidney.

The Day of Surgery

The surgery takes about 3-5 hours. Afterward, you will stay in the hospital for 1-3 nights.

Before the surgery begins:

  • An IV line is put into a vein in your arm or hand. This line delivers fluids and medications (such as antibiotics).

  • To keep you free of pain during the surgery, you’re given general anesthesia. This medication puts you into a state like deep sleep through the surgery. A tube may be inserted into your throat to help you breathe.

  • A thin tube (catheter) is placed into your bladder through the urethra. This drains urine during the surgery and for a time afterward.

During the surgery:

  • If a portion of the ureter is narrowed, that portion is cut out. The lower cut end is then sewn to the kidney. Or, the ureter and kidney are both cut. Part of the kidney is then used to make the ureter wider. If a blood vessel is pressing on the ureter, it is moved away.

  • A long, flexible tube called a stent is put into the ureter. It reaches from the kidney into the bladder. It is kept in place for 4-6 weeks after surgery to help hold the ureter open while it heals.

  • When the surgery is done, all tools are removed. The incision or incisions are closed with sutures, staples, surgical glue, or strips of surgical tape. One or more tubes may be placed near the incision or incisions. These drain fluid from the incision for a short time after surgery.

Recovering in the Hospital

After the surgery, you will be taken to a recovery room. Here, you’ll wake up from the anesthesia. You may feel sleepy and nauseated. If a breathing tube was used, your throat may be sore at first. When you are ready, you will be taken to your hospital room. While in the hospital:

  • You will be given medication to manage pain. Let your providers know if your pain is not controlled.

  • You’ll first receive IV fluids. In a day or so, you will start on a liquid diet. You will then slowly return to a normal diet.

  • As soon as you’re able, you will get up and walk.

  • You’ll be taught coughing and breathing techniques to help keep your lungs clear and prevent pneumonia.

  • The catheter in your urethra and any drains will likely be removed before you leave the hospital. If not, you will be shown how to care for them at home.

Recovering at Home

After your hospital stay, you will be released to an adult family member or friend. Have someone stay with you for the next few days, to help care for you. Recovery time varies for each person. Your doctor will tell you when you can return to your normal routine. Until then, follow the instructions you have been given. Make sure to:

  • Take all medications as directed.

  • Follow your doctor’s guidelines for showering. Avoid swimming, bathing, using a hot tub, and other activities that cause the incision to be covered with water until your doctor says it’s okay.

  • Avoid heavy lifting and strenuous activities as directed.

  • Do not drive until you are no longer taking prescription pain medication and your doctor says it’s okay.

  • Avoid straining during a bowel movement. If needed, take stool softeners as directed by your doctor.

Note: The stent in your ureter will cause the urge to pass urine more often. You may also have some burning and blood in your urine. This is normal and will go away once the stent is removed during a follow-up visit.

Call the Doctor If You Have Any of the Following:

  • Chest pain or trouble breathing (call 911 or other emergency service)

  • Fever of 100.4°F or higher

  • Symptoms of infection at an incision site such as increased redness or swelling, warmth, worsening pain, or foul-smelling drainage

  • Bleeding or a large amount of drainage from an incision

  • Blood clots in your urine

  • Pain or swelling in the legs

  • Inability to urinate

  • Vomiting that doesn’t go away

Follow-Up

You will have follow-up visits with your doctor. If sutures or staples need to be removed, this is done 1-2 weeks after surgery. The stent in the ureter will be removed in 4-6 weeks. About 3 months after surgery, you may have an imaging test. This checks that the ureter is open and the kidney is working normally.

Risks and Possible Complications

Risks of this procedure include:

  • Infection

  • Bleeding (may require a blood transfusion)

  • Leakage of urine at the surgical site

  • Scarring of the ureter

  • Damage to nearby organs

  • Need for further surgery

  • Kidney damage

  • Risks of anesthesia (the anesthesiologist will discuss these with you)
