Q

ways to reduce indwelling cath obstruction

A

Q

urothelial cancer: monoclonal theory vs field theory

A

monoclonal theory states that multiple tumors descend from a single genetically transformed cell that populates the urothelium.

The field theory states that exposure to a carcinogen leads to “cancerization” of the entire urothelium

90
Q

why is nitrofurantoin contraindicted in patients over 65yrs old?

A
  1. nitrofurantoin is not effective in patients with creatining clearance of less then 40 mL/min^2

What are Tamm-Horsfall protein?

A

protein in the renal tubules of the outer medula that bindto bacteria and allow them to wash out in the urine

A

Staphlyococcus saprophyticus is the most common (Enterococcus faecalis
Streptococcus agalactiae, aka GBS) usually represent contamination if isolated from a voided urine sample.

94
Q

why do elderly patients have more urine production at night?

A

ANP increase with age and this lead to increased urine production at night.
