Urogenital Pathology - Urinary System Flashcards
Murphy’s Percussion
Test for costo- vertebral tenderness, used to rule out involvement of the kidney and assess for pseudo renal pain. Positive if patient feels a sharp pain, RED FLAG!
Positive → Inflamed, infected kidney.
Common Signs of Urinary Tract Problems
- Urinary frequency, urgency, incontinence
- Pain (shoulder, back, flank, pelvis, lower abdomen)
- Costovertebral tenderness
- Fever and chills
- Increase of sensitivity
- Dysuria: pain or discomfort during urination
- Hematuria: blood in the urine
- Pyuria: urinal test: increase presence of white cells
- Dyspareunia: pain during intercourse
- Nocturia: need to urinate during the night
Urinary Tract Infection - Types
Pyelonephritis: affects kidneys
Cystitis: affects urinary bladder
Urethritis: Urethra
Upper UTIs: Kidneys or ureteral infection
Lower UTIs: Bladder or urethral infection
Urinary Tract Infection - Etiology and Risk Factors
• Age
• Women greater than men
• Immobility/inactivity (impaired bladder emptying)
• Increased sexual activity
• Prostatic hyperplasia
• Malformations or urinary tract abnormalities
• Pregnancy
• Diabetes mellitus
menopause without hormone replacement therapy
Renal calculi
Cystitis and Urethritis Clinical Manifestation
• Cystitis: inflammation with infection of the bladder
• Interstitial cystitis: inflammation without infection of the
bladder
• Urethritis: inflammation and infection of the urethra
Cystitis and Urethritis Symptoms
Frequency, urgency, dysuria, nocturia
Fever, chills, and malaise may be present
May notice: - Cloudy, bloody, or foul-smelling urine and a burning or painful sensation during urination or intercourse.
- Pain in suprapubic, lower abdominal, groin, or flank areas, depending on location of infection.
Upper Urinary Tract Infection - Most Common
- Acute pyelonephritis: infectious process involving the kidneys.
- Chronic pyelonephritis: inflammatory disease involving the kidney parenchyma and renal pelvis.
- Acute and chronic glomerulonephritis: inflammation of the glomeruli of both kidneys.
Pyelonephritis - Clinical Manifestation Acute vs. Chronic
Acute pyelonephritis is usually abrupt:
Fever, chills, malaise, headache, and flank pain.
May have a positive murphy sign and bladder irritation.
Chronic pyelonephritis: vary depending upon the cause, may have no symptoms. Diagnosis by laboratory detection of kidney function changes.
Renal Cancer - Risk Factors
3-4% of cancers. 90% renal cancers are renal cell carcinoma.
Tobacco smoking, moderate to heavy drinking (alcohol),obesity, hypertension, barbecued meat, occupational exposure to substances such as dust…
Renal Cancer - Clinical Manifestation
- Flank pain
- Hematuria (blood in urine) 50% of cases
- Palpable abdominal mass
Generally silent, especially in beginning.
May develop malaise, anemia and unexplained weight loss (RED FLAG!).
Can influence hormones: PTH, gonadotropins, renin, glucagon and insulin.
Renal Cystic Disease - Definition
Renal cyst: cavity filled with fluid or renal tubular elements making up a semisolid material. Can lead to degeneration of renal tissue and obstruction of tubular flow.
Renal Cystic Disease - Classifications
- Polycystic kidney disease (PKD): requires dialysis and renal transplantation.
- Cystic diseases of the renal medulla
- Acquired cystic disease: secondary to dialysis, diabetes or glomerulonephritis
- Single cyst: Most common and usually do not produce symptoms or compromise renal function
- Cystic renal dysplasia
- Miscellaneous renal cystic disorders.
Polycystic Kidney Disease - Clinical Manifestation/Symptoms
Hereditary, cysts often asymptomatic.
Signs and Symptoms:
- Hematuria, fever, and hypertension
- Abdominal or flank pain (most common symptom)
- Significantly enlarged kidneys, palpable abdominally
Renal Calculi - Definition
Urinary stone disease or nephrolithiasis.
Formed inside the kidney, travels down urinary tract and released with urine. Extremely painful. Can’t locate the pain exactly because it is moving with the stone. Can get stuck.
Renal Calculi - Obstruction
Urinary obstruction typically occurs on three sites:
- the ureteropelvic junction
- where the ureter crosses over the iliac vessels
- at the ureterovesical junction
