An endopyelotomy is a type of surgery to open up an obstruction in your kidney. We can either approach the kidney through the percutaneous nephrostomy tube from the outside (antegrade endopyelotomy) or through the urine channel and urinary bladder, then up through the ureter (retrograde endopyelotomy).
Getting Ready for Surgery
You will need to do bowel prep the day before your surgery. See below for details.
Day Before Surgery
Eat a light breakfast and lunch, avoid greasy foods and red meat.
Drink only clear liquids after lunch until midnight.
Juice without pulp (apple, grape, cranberry)
Clear Jell-O® (must be homemade, not premade; no fruit, etc, in it)
Sparkling water or soda
Weak coffee or tea, no creamer; sugar or sugar substitute is ok.
After lunch, do not eat solid food or drink juice with pulp, dairy products, or alcohol.
_____ At 2:00 pm, drink magnesium citrate 10 oz. (1 bottle; any flavor). Drink 1 liter of a sport-type drink with electrolytes (Gatorade®) before midnight. You should keep drinking clear liquid up until midnight. Do not eat or drink after midnight.
