Chapter 11: Diseases and Conditions of the Urinary System: etiology Flashcards
what is the etiology of Acute Glomerulonephritis
follows streptococcus infection; idiopathic or immune reaction; antibodies trapped in capillaries
what is the etiology of Chronic Glomerulonephritis
immune mechanisms; antibody complexes lodged in glomerular capsular membrane
what is the etiology of Nephrotic Syndrome (Nephrosis)
increased permeability of glomerulus from renal damage
what is the etiology of Acute Renal Failure
diminished blood flow to, infection, damage, or mechanical obstruction of kidneys
what is the etiology of Chronic Renal Failure
end stage of chronic kidney diseases (glomerulonephritis, pyelonephritis, or polycystic kidneys)
what is the etiology of Pyelonephritis
bacterial ascension of urinary tract; renal calculi, tumors, urinary stasis; more women
what is the etiology of Hydronephrosis
obstruction causes pressure in kidney; local growths or calculi cause obstruction
what is the etiology of Renal Calculi
often idiopathic; hereditary; excessive calcium or uric acid in urine; dehydration, infection
what is the etiology of Infectious Cystitis and Urethritis
ascending bacterial infection, STDs; viruses, fungi, parasites, chemotherapy
what is the etiology of Diabetic Nephropathy
diabetic glomerulosclerosis; lesions of glomeruli; filtration rate decreased
what is the etiology of Polycystic Kidney Disease
inherited; acquired -sequela of chronic kidney disease; progresses quickly to ESRD
what is the etiology of Neurogenic Bladder
insult to brain/spinal cord/nerves by trauma or disease
what is the etiology of Stress Incontinence
pelvic floor muscles/urethral structure weakened; pregnancy, childbirth, menopause
what is the etiology of Renal Cell Carcinoma
most sporadic, familial; Hippel-Lindau syndrome; obesity,chemical exposure
what is the etiology of Bladder Tumors
environmental factors: chemicals in air, frequent bladder infections, parasitic worm
