The ureter is the tube that drains urine from the kidney to the bladder. Ureteropelvic junction (UPJ) is the narrowing or scarring of the ureter where it leaves the kidney that can cause slow or poor drainage of urine. This obstruction can cause abdominal pain, stones, infection, high blood pressure and deterioration of kidney function. 

Robotic pyeloplasty provides patients with a safe and effective way to correct UPJ.

During robotic pyeloplastic (kidney reconstruction), Penn urologists remove the segment of the ureter causing the obstruction and re-attach the ureter and kidney to permit more normal urine drainage. We perform the procedure through three or four instrument ports. Unlike open surgery, the small incisions made during robotic-assisted surgery allow the surgeon to repair the blockage, or narrowing of the ureter, without having to place his or her hands into the abdomen.
