Pyeloplasty (Open, Laparoscopic)

Pyeloplasty is a surgery in which the renal pelvis and its connection to the ureter are repaired. The renal pelvis is a funnel-like structure in the kidney. It connects to the kidney to the ureter (tube that carries urine to the bladder).

Pyeloplasty must be done if a blockage is found at the kidney’s connection to the ureter. This blockage causes the kidney to balloon, which is typically detected by ultrasound or CT scan.

General anesthesia is given during pyeloplasty. You will be asleep during the procedure and will not feel any pain. The surgery will take 2-3 hours.

Pyeloplasty may be conducted by open surgery or laparoscopic surgery.

  • During open surgery, an incision is made in your side. The surgeon reconstructs the renal pelvis to remove the blockage. The blocked section of the ureter is removed. The remaining healthy sections are reattached to the renal pelvic tissue.
  • The laparoscopic approach is similar except it is done through small key-hole incisions.

In some surgeries, tubes may be placed in the ureter to help draining. A tube can be easily removed in a doctor’s office about a week after the surgery.

You will receive pain medication to ease discomfort after surgery. You may also experience some discomfort while urinating for the first few times following surgery. It is also common to feel a frequent need to urinate.
