Urogenital 1 of 2 Flashcards
(36 cards)
what is the usual cause of UTI?
Escherichia coli, and other members of the Entercacteriaceae familyu
comprises 1% of all out-patient visits
UTI
what are the affects of spermicide use?
- spermicide increases colonization of vagina with uropathogens
- spermicides increase adherence of Escherichia coli to vaginal epithelial cells
infection of the bladder wall
cystitis
- infection of the bladder wall
- symptoms
- frequency and urgency to urinate and dysuria(painful urination)
- pain and tenderness in suprapubic area
- urine
- malodorous
- bloody
- bacteria and WBC found in urine
most commonly follows bladder infection
pyelonephritis
- an infection of the kidney and renal pelvis
- most commonly follows a bladder infection
- acute
- WBCs
- cellular casts
- bacteria
- protein appear in the urine
- chronic
- gradual nephron loss
- renal failure
inflammation of the urethra usually caused by UTI
urethritis
inflammation in the nephrons, the glomerulus becomes leaky
glomerulonephritis
- inflammation of the glomeruli in the nephrons
- glomerular capillary network becomes leaky allowing plasma protein and blood cells to be excreted in the urine
inflammation of the prostat gland usually follows what process?
what are the three virulence factors for bacteria that cause UTIs?
Virulaence factors
- Adherence to vaginal and uroepithelial cells
- cytotoxic, necrotizing factors
- hemolysin
what determines the anatomical location of infection?
Adhesive properties determine the anatomical location of infection
- adhesion to vaginal and periurethral cells
- avle to coloinize the urethral opening
gram negative rods

can be RBC, WBC,granular or broad waxy
casts- indicate damage or infection of the kidneys

increase numbers in poisoning with ehylene glycol, diabetes mellitus, chronic renal disease, following large vit C intake
calcium oxalate crystals
- common in acid and neutral urines and processed from oxalate-rich foods such as tomatoes, spinach,rhubarb, garlic, oranges and asparagus
