Answer:
One of the factors for the development of pyelonephritis, in addition to E. coli, is urinary retention and reflux (option a).
Explanation:
Pyelonephritis is an infection of the upper urinary tract caused by bacteria in the urine, such as Escherichia coli.
Under normal conditions, urine in the urinary bladder is aseptic, that is, without bacteria. The presence of bacteria in the urine indicates a urinary infection.
Urinary retention is the limitation of the expulsion of urine from the bladder. This promotes:
- <em>An increase in the amount of bacteria present in the bladder.
</em>
- <em>The pressure generated by urine retention causes the bladder to generate a retrograde flow - reflow - towards the ureters, leading the bacteria to the kidneys.
</em>
The result of urinary retention and reflux - when bacteria are present - is an infection in the upper urinary tract, called pyelonephritis.
