OAT Renal Flashcards
What causes cystitis?
Cause: Usually Bacteria
• Population at Highest Risk:
– Sexually active women
– Infants
– Pregnant women
– Elderly
– Catheter patients (most common nosocomial infection)
What sx make you think cystitis? what tests would you run to confirm?
• Common Symptoms:
– Dysuria, Hematuria, Frequency, Urgency, Fever, Lower Abd Pain
• Tests:
– Midstream urinary analysis (UA), Lloyd’s Punch (R/O Pyelonephritis)
*unexplained blood in urine is malignancy until proven otherwise
How do we treat cystitis? what can happen if we don’t treat?
• Treatment:
– Appropriate Abx Therapy
– Increase fluid intake
– OMT as Tolerated
• Serious Complications:
– Pyelonephritis
If we see unexplained blood in the urine, what is the first dx until proven otherwise?
malignancy
What is the common term for nephrolithiasis?
kidney stones
How does nephrolithiasis present? most common stones?
- Severe colicky flank pain with radiation into the groin
- Calcium Oxalate, Calcium Phosphate
How do we dx nephrolithiasis?
- UA –> looking for blood, crystals, signs of infection
- CT without contrast
*stone analysis should be performed when possible
Why do we analyze stones?
based on the stone passed behavior modifications can help prevent future problems
How do we tx nephrolithiasis?
- Conservative managment: aggressive hydration and dietary modification
- Urologic Intervention undertaken when patients do not respond to conservative management
What behaviors help to avoid renal calculus formation?
- Minimum intake of 2 L water/day
- Avoid strictly vegetarian diets
- Avoid excessive animal protein diets, salt consumption, vitamin C/D consumption, soft drinks
- consume phytate-rich foods (such as bran, legumes, beans, wild rice, Brazil nuts)
What nerve is responsible for the pain with kidney stones?
genitofemoral n.
What is interstitial cystitis?
painful bladder syndrome
*more common in women
What sx make you think interstitial cystitis?
– Pain in the pelvis, between the vagina and anus, between the scrotum and anus
– A persistent, urgent need to urinate
– Frequent urination
– Pain or discomfort while the bladder fills and relief after urinating
– Pain during sex
How do we dx interstitial cystitis? tx?
- H&P, bladder diary, pelvic exam, UA with cytology, Cystoscopy with biopsy, potassium sensitivity test
- PT, NSAIDS, Tricyclic antidepressants, antihistamines (decrease urgency and frequency), Pentosan polysulfate sodium* (Elmiron; possibly helps restore the inner surface of the bladder), OMT
*Elmiron; possibly helps restore the inner surface of the bladder; may take 2-4 months to notice relief
*no tx is definitive
What normal changes do we see in the kidney with age?
- Decreased GFR
- Glomerular, vascular, and accompanying parenchymal changes occur
- The number of nephrons is reduced, and creatinine clearance declines
*have to be careful with drug toxicity
