UNIT 3- RENAL & UROLOGIC PROBLEMS Flashcards
What is the patho of a UTI?
- Bacteria enters the sterile bladder causing inflammation
- Cystitis vs. Pyelonephritis Vs. Urosepsis
- May be caused by a variety of disorders
-Bacterial infections most common
- Fungal and parasitic infections may cause UTIs
What is the most common pathogen of UTI infections?
- Escherichia Coli (E.Coli)
What is the patho of catheter-associated urinary tract infection?
Causes:
1. E.coli
2. Less frequently: pseudomonas sepcies
Most CAUTI infections are underrecognized and undertreated?
Yes
What are the classifications of UTI
Lower UTI– urethritis or cystitis
Upper UTI– pyelonephritis
Urosepsis
What is pyelonephritis?
Inflammation of renal parenchyma and collecting system (usually caused by infection)
What is urethritis
Inflammation of the urethra
What is cystitis?
Inflammation of the bladder
What is urosepsis?
A UTI that has spread systemically (this is life threatening) requiring emergency treatment
What are risk factors for UTIs?
- Immunosuppressed/immunocompromised
- Diabetes
- Hx of kidney problems
- have undergone multiple antibiotic courses
- Have traveled to developing countries
- Catheterization
- Cystoscopy examination
- Occupation/habitual delay
- STI
Multiple sex partners (women), poor hygiene, menopause, bubble baths, feminine sprays and pregnancy are all risk factors for what?
True
What is the patho of a lower tract UTI
- Usually, no systemic manifestations
What are two types of lower tract UTIs
- Urethritis
- Cystitis
What are s/s of urethritis?
- Pain/burning/difficult urination (dysuria)
- Frequency
- Urgency
- Males: clear mucous-like discharge
- Females: lower abdominal discomfort
- Nocturia
What are s/s of cystitis?
- Pain/burning/difficult urination (dysuria)
- Frequency
- Urgency
- Males: clear mucous-like discharge
- Females: lower abdominal discomfort
- Nocturia
- BLADDER IRRITABILITY
- HESITANCY
- SUPRAPUBIC PAIN
- INCONTINENCE
- NOCTURNAL ENURESIS
What will a lower UTI UA show?
1.+Nitrates: indicate bacteriuria
- WBC, +Leukocyte esterase– enzyme present in WBCs, indicating pyruia
What does the Urine c/s determine for UTIs
Determine bacteria’s susceptibility to antibiotic drugs
Uncomplicated UTI antibiotics typically run for?
3 days
Complicated UTI’s antibiotics typically run for?
- Longer treatment (usually 7-14 days)
What is our goal for lower UTI’s
To have relief from bothersome symptoms; prevent upper UTI/involvement, and have no recurrence
What is the patho of an Upper Tract infection
- Renal parenchyma, pelvis and ureters can be effected
- typically causes fever, chills, flank pain
- Usually begins with lower UTI
- Pre-existing factor may present
- Vesicoureteral reflex
- Retrograde (backward) movement of urine from lower to upper urinary tract
Besides pre-existing factors what other things can cause upper tract UTI?
Dysfunction of lower urinary tract
1. Obstruction from BPH
2. Stricture
3. Urinary stone
- CAUTI
Recurring episodes lead to scarred, poorly functioning kidney and chronic pyelonephritis.
What are the classic manifestations of pyelonephritis?
- Fever/chills
- N/V
- Fatigue/Malaise
- Flank pain/pain at costovertebral angle
True or false: Pyelonephritis may require hospitalization?
True
True or false: you don’t have to worry about urosepsis with pyelonphritis?
False- monitor for urosepsis– close observation and VS monitoring
What is the patho of Urosepsis?
- UTI that has spread systemically
- Life- threatening condition requiring emergent treatment.
What should we know about urosepsis?
- Systemic infection from urologic source
- Prompt diagnosis/treatment critical
- Usually begins lower tract and ascends urethral route
What are frequent causes of urosepsis?
- E.coli
- Proteus
- Klebsiella
- Enterobacteria
What are clinical manifestations of urosepsis?
- Malaise/fatigue
- Chills/fever
- N/V
- Characteristic of cystitis
-dysuria, urgency, frequency - Costovertebral tenderness of affected side
- Elderly present with delirium
- Vs changes (fever, HR increase, BP decreases)
What are UTI treatments and preventions?
- Antibiotics (IV vs PO)
- NSAIDs or antipyretic drugs
- Vitamin C
- Urinary analgesics
-Phenazopyridine (Pyridium) - Fluids
-IV- Cranberry juice— low sugar
What teaching should you include with UTIs/urosepsis?
- Disease process
- Prevention of UTI
- Medication use
- Pain management
- Follow up appointment
- Rest
- Dietary education and fluid intake
How can you prevent cystitis?
- Drink 8-10 glasses of fluid per day… encourage unsweetened cranberry juice
- Women should wipe front to back
- Avoid vaginal douches, bubble baths, powders, or sprays
- Urinate after intercourse
