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.
The urinary tract obstruction means impeding urine's flow in the normal path that includes kidneys, ureters, urethra and bladder. It can lead to kidney problems such as kidney damage,stones and even infection. The 25 years old female diagnosed with this has hydronephrosis and decreased GFR caused by the dilation of renal pelvis and calyces adjacent to a blockage.
