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.

UI	MeSH Term	Description	Entries
D007669	Kidney Calculi	Stones in the KIDNEY, usually formed in the urine-collecting area of the kidney (KIDNEY PELVIS). Their sizes vary and most contains CALCIUM OXALATE.

D007670	Kidney Calices	Recesses of the kidney pelvis which divides into two wide, cup-shaped major renal calices, with each major calix subdivided into 7 to 14 minor calices. Urine empties into a minor calix from collecting tubules, then passes through the major calix, renal pelvis, and ureter to enter the urinary bladder.

D009403	Nephrostomy, Percutaneous	The insertion of a catheter through the skin and body wall into the kidney pelvis, mainly to provide urine drainage where the ureter is not functional. It is used also to remove or dissolve renal calculi and to diagnose ureteral obstruction.	Percutaneous Nephrostomy,Nephrostomies, Percutaneous,Percutaneous Nephrostomies

D014463	Ultrasonography	The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.

D014517	Ureteral Obstruction	Blockage in any part of the URETER causing obstruction of urine flow from the kidney to the URINARY BLADDER. The obstruction may be congenital, acquired, unilateral, bilateral, complete, partial, acute, or chronic. Depending on the degree and duration of the obstruction, clinical features vary greatly such as HYDRONEPHROSIS and obstructive nephropathy.
