– BPH
Also: Caffeine intake
Urinary Frequency: Red Flags
– Lower extremity weakness or signs of spinal cord damage
– Fever and back pain
Acute Kidney Injury (AKI): Acute Renal Failure
• Described as the rapid decrease in renal function over days
(Reduced blood flow to kidney allows creatinine and urea build up, leading to fluid/electrolyte disorders)
AKI: Complications
Fluid build up in lungs, chest pain, kidney damage, death
Acute Kidney Injury: Initial Symptoms & Signs
-Weight gain & peripheral edema
AKI: Later symptoms & signs
-Oligouria
-Anorexia
-Nausea, vomiting
-Back pain
-Confusion, anxious, restless
-Diarrhea
-Fatigue, lethargy
-Hypertension
-Weakness
AKI: Diagnostics
-Increased uria & creatinine (takes 24 hours for creatinine to increase)
AKI: Treatment
-Immediate Care (Can be serious-lead to coma, death)
Kidney (Renal) Trauma
-Kidney is injured by outside force: Penetrating/Blunt Trauma
Kidney (Renal) Trauma: Possible other symptoms
– Hematuria
– Diffuse abdominal tenderness
– Flank contusion
– Lower rib fractures
– Skin wound
Kidney (Renal) Trauma: Exam
– Look for any signs of trauma, contusion or redness
Kidney (Renal) Trauma: Lab Test
– Hematuria, low hematocrit
Kidney (Renal) Trauma: Treatment
– Depends on injury & situation
– May need surgery
– Most blunt trauma is low grade: Treatment is bed rest until gross hematuria resolved)
Chronic Kidney Disease
• Defined as long-standing, progressive deterioration of renal function
Chronic Kidney Disease: Risk Factors
– Analgesic use
– Hypertension
– Smoking
– Obesity
– African-American or Native American
– Older age
– Family history of kidney disease
Chronic Kidney Disease: Most common causes
• Diabetic nephropathy
• Hypertension
• Glomerulonephritis
Chronic Kidney Disease: Additional Causes
• Polycystic kidney disease
• Vesicoureteral reflux
• BPH
Chronic Kidney Disease: Possible Symptoms
(Typically asymptomatic or few symptoms)
• Anorexia
• Nausea, vomiting
• Nocturia
• Fatigue
• Pruritus
• Edema of feet/ ankles
• Urinary issues
• Muscle twitches and cramps
Chronic Kidney Disease: Complications
• Pulmonary edema, hyperkalemia, heart issues
• Central nervous system: difficulty concentration, personality change
Glomerular Disease
• Reduces kidneys ability to filter
• Red blood cells and protein may be excreted into the urine while toxins may be retained
Glomerular Disease: Basic Types
Nephrititic & Nephrotic
Glomerular Disease: Complications
• Hypertension, kidney failure
Nephritic Syndrome (glomerulonephritis)
• Bacterial or viral infection causes diffuse inflammation and damages the glomeruli
Nephritic Syndrome ( Glomerulonephritis): Epidemiology
– Most common in children (60% ages 2-12, 10% >40)
– Predominately males
Nephritic Syndrome (Glomerulonephritis): Causes
– Previous infections such as strep
