Ureteropelvic junction obstruction

Abstract

The diagnosis of ureteropelvic junction obstruction (UPJO) implies functionally significant impairment of urinary transport from the renal pelvis to the ureter. Although most cases are probably congenital in origin, the problem may not become clinically apparent until much later in life. This chapter is limited to a discussion of the treatment of congenital UPJO, although at times these techniques may be applied appropriately to the management of some related acquired conditions. © 2006 Humana Press Inc.
