Answer True
Women have a shorter urethra that puts them at higher risk for developing a UTI.
Which of the following is a risk factor for the development of a urinary tract infection (UTI)? -
Answer Pregnancy is a risk factor the development of a UTI.
Which of the following is true regarding a complicated urinary tract infection? - Answer A
complicated UTI can be caused by a structural issue in the urinary tract.
A symptom of a lower urinary tract infection includes: - Answer Urgency is a symptom of
lower tract UTI.
Which of the following can help to prevent a UTI? - Answer Water consumption prevents UTI
as it keeps bacteria flushed out of the urinary tract.
Urinary Tract Infections - Answer Urinary tract infections (UTI) are commonly seen in clinical
practice. Bacteria from the gut can invade the urinary epithelium to cause inflammation and
infection anywhere along the urinary tract such as the urethra, bladder, ureter, or kidney. Some
individuals are predisposed to developing a UTI. It is more common for women to develop a UTI
especially when pregnant, sexually active, during post-menopause with estrogen-deficiency and
when being treated with antibiotics where the normal bacteria flora is diminished. Although
less common, men may develop a lower UTI. An upper UTI is less common in men due to the
longer urethra and ureter structures that make it more difficult for bacteria to reach the kidney.
An indwelling urinary catheter can also contribute the development of a UTI. Finally, individuals
who experience urinary obstruction, diabetes or neurogenic bladder are also at risk for
developing a UTI.
A UTI can be discussed in terms of its severity. It can be complicated or uncomplicated. It can
also be discussed according to its location, where it can occur anywhere along the urinary tract
(upper vs. lower tract disorders). It is under these categories that UTI will be discussed. Finally,
common organisms that cause UTI are covered. This information is essential as the NP is
responsible for identifying the organism so that appropriate treatment can be initiated.
The diagram below compares the male and female urinary tracts. Note that the female has a
shorter urethra which predisposes her to an increased risk of infection than the male.
UTI Patho - Answer The pathophysiology of a UTI is simple. First, bacteria enter and
contaminate the lower urinary tract. This causes the colonization of bacteria in the urethra and
the bladder which triggers an inflammatory response in the lower urinary tract. Neutrophils are
,recruited to the area where the bacteria are present. The bacteria multiply which allows them
to evade the immune system due to virulent factors. For example, Escherichia coli can bind to
cells in the lower urinary tract and hide from the immune cells. The bacteria can form biofilms.
A biofilm is any group of microorganisms that allow them to stick to one another and adhere to
surfaces that help them survive. If the UTI progresses or is not treated, or if the patient is
immunocompromised, the bacteria can ascend to the kidneys and colonize there. At this point,
the infection becomes an upper UTI. From there, if left untreated, the bacteria can spread into
the circulation via the renal veins causing bacteremia that could potentially lead to septic shock.
UTI Risk Factors - Answer There are several risk factors that predispose individuals to the
development of a UTI. For women, pregnancy is a risk factor. During pregnancy, progesterone
relaxes smooth muscle that causes stasis of urine, allowing the bacteria to colonize. Also, the
female ureter is shorter and allows for the entrance of bacteria into the urethra.
Post-menopausal women are also at risk for developing a UTI. The lack of estrogen results in
vaginal and urethral dryness that promotes an environment for bacteria to grow. Sexual
intercourse also contributes to the development of a UTI where bacteria can be easily
introduced into the urethra. If spermicides are used during sexual intercourse, this also puts the
woman at risk for a UTI.
Indwelling urinary catheterization is also a major cause of a UTI, especially in females. The
catheter itself can introduce infections directly into the bladder. The bacteria will colonize in the
bladder and initiate an immune response. The neutrophils enter the area to further promote
inflammation. Fibrinogen accumulates on the catheter which provides an ideal environment for
the attachment of uropathogens that express fibrinogen-binding proteins. After the initial
attachment to the fibrinogen-binding proteins on the catheter, the bacteria multiply to form
biofils. This results in epithelial damage to the urinary tract that leads to a kidney infection.
Lower vs. Upper Tract Disorders - Answer A UTI can be discussed in terms of its location.
Note that a UTI can occur anywhere along the urinary tract and can be associated with another
issue in the area. For example, if the infection occurs at the opening of the urethra, then the
condition is termed urethritis. Overall, cystitis is a condition of the lower urinary tract that
denotes a bladder infection. Cystitis can occur in both females and males. In males, the cystitis
may be associated with prostatitis.Recognizing the signs and symptoms of the UTI is important
in categorizing it as either a lower or upper urinary tract disorder. In a lower urinary tract
disorder, the individual experiences urgency associated with burning on urination. Other
common symptoms of a lower UTI is frequency, dysuria, and suprapubic pain. The urine may
also appear cloudy and have an odor.
An infection of the lower urinary tract can progress to an upper urinary tract infection if the
bacteria ascends from the bladder to the kidney. The condition is pyelonephritis. Because the
infection involves the kidney, it is a more serious condition as it can cause acute renal failure if it
is not treated. The signs and symptoms of pyelonephritis include all the symptoms associated
with cystitis plus fever, flank pain, costovertebral angle (CVA) tenderness, nausea, and vomiting.
Malaise is also a common complaint for the patient with pyelonephritis. There can also be signs
of shock if the infection has entered the circulation from the kidney via the renal vein. Think of
the symptoms of pyelonephritis in a classic triad: vomiting, flank pain and fever.
Lower vs. Upper Tract Disorders - Answer The NP can also collect a urine sample to
determine the presence of a lower vs. upper UTI. A urine dipstick can be observed for the
, presence of leukocyte esterase and nitrites. These should be considered together when
diagnosing a UTI. Leukocyte esterase is an enzyme that is released by the WBCs (leukocytes). It
is a qualitative measure of WBCs in the urinary tract. On the actual dipstick test, you may just
note leukocytes. But note that the dipstick does not measure the number of leukocytes. It just
provides an indication of enzyme activity and the presence of inflammation. Using the urinalysis
to diagnose a UTI is covered in a section below.
Initially, a urine dipstick can be performed to identify hematuria, proteinuria, and the presence
of nitrites. The presence of nitrites is highly specific for bacterial infection. Note that an
individual can have a negative urine dipstick but still present with signs and symptoms of a UTI.
If this is the case, then the NP can send the urine for a culture and sensitivity (C&S) test and
microscopy.
On microscopic exam of the urine, a patient with cystitis will have a white blood cell (WBC)
count of greater than 5000 high power field (hpf) and hematuria. For the patient with
pyelonephritis, the urine will present with WBC casts. The presence of casts in the urine
indicates that the protein in the lumen of the kidney tubules has solidified, especially in the
nephron. This indicates kidney disease rather than a lower UTI.
Uncomplicated vs. Complicated Urinary Tract Infections (UTI) - Answer A UTI may be
classified as complicated or uncomplicated in terms of its severity. An uncomplicated UTI
indicates that the urinary tract and renal function is normal. In a complicated UTI, there is
decreased renal function and an abnormal urinary tract. In differentiating between a lower and
upper UTI above, the presence of WBC casts indicates the presence of kidney involvement
which requires a more complicated treatment plan. The patient is also at higher risk for
extensive and permanent kidney damage as well as sepsis. If sepsis is suspected, a blood culture
may be drawn to identify the causative organism or rule it out.
The severity of the UTI can also be determined based on the interventions that are necessary to
treat the infection. The more intervention required, the more complicated the infection. In
general, individuals are treated for a UTI only when they are symptomatic. Although the urine
results may confirm a UTI, if the patient denies symptoms, then an antibiotic is not prescribed.
The exception would be during pregnancy due to the ureteral dilation that occurs that increases
the risk for pyelonephritis. Even though she may be asymptomatic, treatment would be initiated
to prevent damage to the fetus in utero. An uncomplicated, symptomatic UTI (cystitis) will
typically require a 3-7 days course of appropriate antibiotic therapy. A complicated UTI
(pyelonephritis) will require intravenous (IV antibiotics) until the patient is afebrile, followed by
a course of oral antibiotics. Overall, the course of antibiotics for a complicated infection is longer
than in an individual that has an uncomplicated infection.
Uncomplicated vs. Complicated Urinary Tract Infections (UTI) - Answer Intervention may also
require the assistance of specialists in the case of a complicated UTI. A referral to a urologist is
necessary if the individual does not respond to antibiotic treatment or if there are recurrent
UTIs, specifically 3 or more in one year. Because upper UTI is uncommon in males, they should
be referred to a urologist. Finally, the presence of hematuria would warrant a referral to the
urologist to determine the presence of significant renal disease.
Finally, sometimes the patient's presentation can seem complicated when examining the patient
who has symptoms like a UTI but may be something else. For example, when there is vaginal
discharge or itching involved, the NP may need to include a genital exam as well to rule out or
diagnose a sexually transmitted infection (STI).
