Answer: Dilation of the renal pelvis
and calyces proximal to a blockage
The urinary tract obstruction is a
blockage of the flow of urine out of the body. It is characterized by the dilation
of the renal pelvis and calyces proximal to a blockage, which results to
hydronephrosis and progressive fall in glomerular filtration rate (GFR).
Moreover,
it is expected that the obstruction is due to a reduction in nephron glomerular
filtration rate and a reduced number of filtering nephrons.
