Modue 6 Flashcards
Dysuria
is the subjective experience of pain or a burning sensation on urination and can also be accompanied by urinary frequency, hesitancy, urgency, and strangury (slow, painful urination).
However, dysuria is most commonly associated with
lower urinary tract infection
Meds that cause dysuria
SSRIs
opiates
scopalamine
the easiest, least invasive, and most economical way to identify urinary tract infections and other renal problems
Urinalysis is
Hematuria
is defined as blood in the urine and can be visible (gross) or occult (microscopic
Asymptomatic microhematuria has many benign causes such as
infection, menstruation, vigorous exercise, viral illness, and trauma
On microscopic examination, hematuria is characterized by more than
three red blood cells (RBCs) per high-power microscopic field (hpf)
Transient hematuria
occurs on a single occasion whereas persistent hematuria occurs on two or more consecutive occasions. Both transient and persistent hematuria can be a sign of serious underlying disease
RBC casts usually indicate
injury to the nephron and are diagnostic of hematuria of renal origin.
intact uniform RBCs with no casts suggests
hematuria originating in the lower urinary tract
The presence of both proteinuria and hematuria is suggestive of
glomerular or interstitial nephritis.
bladder irritants- dietary substances such as
caffeine, spices, tomatoes, chocolate, aged cheeses, citrus fruits, and soy sauce may act as bladder irritants. Alcohol and cigarettes are also bladder irritants
questions to ask with hematuria
menstrual hx
exercise
recent strep infection?
family hx
recent travel
Hematuria accompanied by colicky flank pain suggests a
ureteral stone
When bleeding occurs only at the beginning or end of urination,
a prostatic or urethral source is likely
Hematuria accompanied by hypertension, edema, and a sore throat or a skin infection may be indicative of
poststreptococcal glomerulonephritis
The most important diagnostic tool in cases of hematuria is .
urinalysis

Proteinuria is
usually indicative of renal pathology, most often of glomerular origin. Proteinuria can be functional as a result of acute illness, emotional stress, or excessive exercise, in which case it is a benign process or simply a resultant sign of a transient condition.
Bence Jones proteinuria (characterized by free monoclonal light chain components of immunoglobulin proteins) may also be associated with
lymphosarcoma, Hodgkin’s disease, and leukemia.
the standard dipstick proteinuria test does not detect
Bence Jones proteins or other light chain immunoglobulins, as it is most sensitive to larger proteins such as albumin.
the most accurate way to quantify the amount of protein in the urine is with
a 24-hour urine collection;
A 24-hour urine collection with more than
150 mg of protein is considered abnormal, and a specimen with more than 3.5 g is indicative of a nephrotic process.
If renal function is normal in a patient with elevated urinary protein, the patient should be
evaluated for orthostatic proteinuria.
Sexually transmitted infections (STIs)
in men and women are caused by viruses, bacteria, and parasites and can occur in the throat, eyes, anal and perianal areas, external genitalia, vestibular glands, vagina, cervix, uterus, or adnexa
Common STIs include
herpes simplex virus (HSV),
human immunodeficiency virus (HIV),
human papillomavirus (HPV),
Chlamydia trachomatis,
Neisseria gonorrhoeae,
Trichomonas vaginalis, and
Treponema pallidum (the causative agent of syphilis)
Transmitted infections via sexual contact but not considered STIs
hepatitis B virus (HBV), hepatitis C virus (HCV), molluscum contagiosum, pediculosis pubis, scabies, and methicillin-resistant Staphylococcus aureus
most prevalent communicable diseases in the United States after upper respiratory infections,
STIs
The most common STI is
genital HPV,
most commonly reported STI
chlamydia
STIs disproportionally affect
adolescents and young adults between the ages of 15 and 24 years, primarily because of increased sexual encounters and risk-taking behaviors
STI High-risk groups also include
men who have sex with men and racial minorities
Estimation of infection of STI (not including HIV_
1 in 5
STIs that can be treated with abx
chlamydia,
gonorrhea,
syphilis,
and trichomonas
Condition that if left untreated can lead to PID
mucopurulent cervicitis
PID
causes inflammation and formation of scar tissue in the genitourinary tract, which can result in a higher risk of miscarriage, ectopic pregnancy, and infertility
In men, untreated chlamydia, gonorrhea, and trichomoniasis can cause
asymptomatic urethritis, epididymitis, and prostatitis and lead to disseminated gonococcal infection.
In both men and women, untreated syphilis may lead to
a tertiary form of infection that can cause serious injury to the central nervous system (CNS), aortitis, and nodular granulomatous lesions on the skin, bone, and solid organs known as gummas
most common virus caused STI
HPV
most serious viral STI
HIV- progresses to AIDS
The female reproductive tract is naturally protected from infection by several mechanisms, i
ncluding a low acidic pH resulting from vaginal secretions and the presence of commensal nonpathogenic microbial flora, namely hydrogen peroxide
alterations of the vaginal pH can occur from
hormonal influences, aging, douching, antibiotic use, exposure to semen, existing infections, and underlying diseases such as diabetes.
Susceptibility to sti is also influenced by
aging and the presence of an existing infection
The incidence of chlamydia and HPV infections is higher in young women because
the squamocolumnar junction, a vulnerable area for infection, is prominent on the ectocervix
presence of one sti
increases risk of another
Women with __________________________________ can transmit these diseases to a fetus during pregnancy and to infants via breastfeeding
HIV, HSV, and syphilis
symptom of most STIs
asymptomatic
painless lesions that usually resolve on their own but are, nevertheless, still infectious
chancre with initial stage of syphilis
HPV infection
symptoms of chlamydia and gonorrhea may not present until
PID develops,
may indicate presence of STI
erythema, inflammation, or a lesion
HPV lesion may appear
warty
HSV lesions may be
vesicular
Normal vaginal discharge is
clear or white
Odorous, purulent, and colored discharge is found in
BV, chlamydia, gonorrhea, and trichomonas
