laparoscopic pyeloplasty

Laparoscopic Pyeloplasty is a minimally invasive method that is used to treat a blockage of urine flow from the kidney to the bladder due to an ureteropelvic junction obstruction.


Make sure you that either your doctor has your films or that you bring them with you to surgery. These are an integral part of the procedure for your doctor in recognising the correct surgical site.

  • Drink clear fluids for a 24-hour period before to the date of your surgery (please see attachment 1, Clear Liquid Diet). Nothing by mouth after midnight the night prior to surgery.
  • Aspirin, Motrin, Ibuprofen, Advil, Alka Seltzer, Vitamin E, Ticlid, Coumadin, Lovenox, Celebrex, Voltaren, Vioxx, Plavix and some other arthritis medications can cause bleeding and has to be avoided 1 week prior to the date of surgery (Please contact your surgeon’s office if you are unsure about which medications to stop before to surgery. Do not stop any medication without contacting the prescribing doctor to get their approval).

The Operation Right after being under anesthesia, the surgeon is going to pass a scope into the bladder and perform an x ray to confirm the site of the obstruction and insert an internal ureteral stent. A ureteral stent is a hollow tube that will go from the kidney to the bladder and helps with urine drainage during the healing process. It is temporary and is removed in the doctor’s office 4-6 weeks following surgery. The stent is not visible from outside the body.

After the stent is placed , 3 to 4 small incisions (5-10 mm) are placed into the abdomen. A telescope connected to a camera and several working instruments will be passed through these “keyholes”. This allows the surgeon to have an enlarged view of inside the body on a video monitor to guide him through the entire procedure.
