Study Notes
Urinary Tract Infections (UTIs)
- The most common cause of UTIs is Escherichia coli (E. coli), responsible for approximately 80% of UTI cases.
- Cystitis is an infection of the bladder, which is the lower part of the urinary tract.
Upper UTIs vs. Lower UTIs
- Upper UTIs are considered more serious because they can cause kidney damage and are more likely to spread to the bloodstream.
Infection Types
- The second most common type of infection after UTIs is respiratory tract infections.
Predisposing Factors
- Factors that increase the risk of UTIs include: diabetes, kidney stones, spinal cord injuries, and poor toilet habits (wiping from back to front in women).
- A disorder that can suppress the immune system and increase the risk of UTIs is diabetes.
Demographics
- The incidence of UTIs is higher in women, especially in those who are sexually active.
- In men, the incidence of UTIs increases with age, with approximately 30% of men experiencing an increase in UTI incidence in old age.
Bacteria
- Staphylococcus Saprophyticus is a type of bacteria that is commonly responsible for UTIs, specifically in young women.
- Staphylococcus Saprophyticus is a type of Gram-positive bacteria.
Nitrofurantoin
- The mechanism of action of Nitrofurantoin in treating UTIs is by inhibiting bacterial DNA synthesis.
- Nitrofurantoin is not suitable for treating upper UTIs or systemic infections because it is concentrated mainly in the urinary tract and does not achieve high concentrations in the bloodstream.
- Nitrofurantoin is mainly concentrated in the urine, where it can effectively treat lower UTIs.
Test your knowledge on urinary tract infections (UTIs), the types of infections in the urinary tract, and the importance of urinary antiseptics. Learn about the differences between upper and lower urinary tract infections, and their associated symptoms.
