Obstructive uropathy

Abstract

Obstructive uropathy is the leading cause of chronic kidney disease in children. It may be caused by upper or lower urinary tract obstruction and most often hydronephrosis on renal ultrasound is the first indicator of obstruction. The key in management of these patients is determining if hydronephrosis is due to obstruction, and this can be done with further imaging such as a nuclear scan or magnetic resonance urography. Once obstruction is confirmed, the crucial step is to bypass the level of obstruction and drain the urinary tract so as not to compromise renal function.
