Congenital obstructive nephropathy is the primary cause of end-stagerenal disease in children. Rapid diagnosis and initiation of the treatment are vital to preserve function and/or to slow down renal injury. Obstr uctive uropathy effects-decline in the plasmatic renal flow and glomerular filtrationrate, interstitial infiltrate of leukocytes, significant decrease of the urine concentration, loss of the capacity to concentrate urine as well as fibrosis and apoptosisare a consequence of a variety of factors that work in complex ways and are still not fully understood. Mediators as angiotensin II, transforming growth factor-b (TGF-b) and nitric oxide (NO) have been implicated in congenital obstructive nephropathy. The renin-angiotensin system is regulated in... |
