Answer:
b. insertion of a cannula into the external iliac vein
Explanation:
A saphenous cutdown refers to a skin incision associated with insertion of a cannula into the external iliac vein.
It is a more invasive method of exposing the saphenous vein. A cut is made into the skin which is not very deep. A part of vein is exposed which is then cut out for the insertion of cannula. It does not stop the flow of blood, instead it just changes the course. It is also known as the circulatory blood flow.

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.
