title: [Intrarenal percutaneous surgery in calyceal stones, infundibular stones, calyceal diverticuli and stenosis of the ureteropelvic junction].
abstract: Percutaneous intrarenal surgery makes it possible to treat calculi and an underlying outlet obstruction in a one-step procedure. We performed percutaneous repair in ten patients with infundibular stenosis, three with calyceal diverticula, and ten patients with recurrent ureteropelvic-junction obstruction. In six patients, it proved possible to remove otherwise inaccessible stones after incision of a parenchymal bridge. Our patients included four children. The operative techniques used are presented. There is a certain risk of injuring an artery, which can be greatly reduced when the renal anatomy is borne in mind. Access above the 12th rib was used frequently. The long-term results demonstrate the efficacy of percutaneous surgery.
