Urology: Pyeloplasty

What is pyeloplasty?

A pyeloplasty is a surgical reconstruction of the renal pelvis to correct a blockage. This classic treatment of ureteropelvic junction obstruction is an open operation to remove the UPJ and to reattach the ureter to the pelvis of the kidney creating a wide junction between the two. This operation, called a pyeloplasty, allows rapid and easy drainage of urine produced by the kidney and relieves symptoms and the risk of infection. The procedure usually takes a few hours and has a success rate in excess of 95 percent with one operation. Hospitalization after surgery depends on the age of the patient. There are a variety of drainage tubes utilized to promote healing and their use is dependent on the surgeon's preference. The incision is usually just below the ribs and just behind a line that would pass from the patient's arm to their leg on the affected side. The incision is usually two to three inches long.
