Pyeloplasty is a type of surgery to repair a blockage where the ureter connects to the kidney. This area is known as the ur-e-ter-o-pel-vic junction (UPJ). After the blockage is removed and the ureter is repaired, a small tube called a stent is left in place to aid healing. This surgery can be done by laparoscope or through a larger incision.

After Surgery

  • You will be in the hospital for 2-3 days.

Incision Care

You may shower once you are home. Do not soak in a hot tub, bathtub, or swim until it is healed. This may be at least 2 weeks. 

Wear a bandage if your incision is draining, rubbing on your clothes, or is in a skin fold. Change the bandage at least once each day. Change it more often if it gets wet. Do not use lotion, powder, or ointment on your incision. 

Look at your incision daily. If you notice signs of infection call your doctor.
