Above iliac it's from the mdial side, bleow iliac its from the lateral side
Difference b/t obstructive uropathy and obstructive nephropathy
Nephropathy implies damage to renal perenchyma
Describes the radioligic findings associated with renal obstruction
Gross changes in obstruction
Hydronephrosis possible, compression of papillae/calyceal blunting, thinning of perenchyma
3 phases of acute obstruction:
1. Increased BF and ureter pressure. 2. Decreased BF and increased ureter. 3. Decreased both
How long until an obstruction does permananet damage
2 weeks ("so you can follow up to 1 week")
What is diagnostic for a stone in Diuretic Renography
t1/2 > 20 (t1/2 = 10-20 is inconclusive)
What is diagnostic for a stone in a whitaker test?
> 22 cmH20
How much is too much w/ postobstructive diuresis
> 200 ml/hr for more than two hours requires treatment (D5 saline)
Which type of stone is radiolucent
uric acid
Which stones are the most common?
Calcium oxalate +/- calcium phosphate
Citrate & kidney stones?
Citrate inhibits stone formation (as does alkaline urine)
Which diuretics prevents calcium stone formation?
Name 4 urease producing bacteria
Proteus, Klebsiella, Pseudomonas, Staph
What amino acids are responsible in cystinuria
Cystine, Ornathine, Lysine, Arginine.
Treatment for hypercystinuria --> prevents deposition.
Secretory status and recurr UTI
Recessive (a-b-) and nonsecreter (a+b-) are more disposed to recurrent UTI (Referes to secretion of Ab's)
Four factors that promote UTI
SEAS - Sex, Estrogen dep, Antimicrobials, Spermicide
Common pathogens in outpatient
E COLI, Staph, Proteus/Klebs/Enterococci
Common pathoegens in inpatient
E coli, Proteus/Klebs/Entercocci, Pseudomonas/Serratia/Achinetobacter
Where can you find quiescent bacteria in the bladder?
In the intermediate cells (below the umbrella cells)
What counts as a 'Complicated' urinary tract infect.
Immunocomp, Diabetic, Pregnant, Catheterized, Resistant bacteria.
First and second line UTI treatment
1: TMP 2. Usually Fluorquinolone or Fosfomycin (or nitrofurantoin)
Where is most BPH
periurethral region
Where is most Prostatic Cancer
Peripheral zone
Condyloma Acuminatum
Epithelial proliveration from HPV (venereal warts)
Which HPV strains cause condyloma acuminatum
HPV-6, 11, and sometime 16
What are the three zones of the prostate, and how are thye correlated w/ cancer/BPH
Central, Transition(BPH) and peripheral (Cancer or inflam)
Which type of cell most commonly develops prostatic adenocarcinoma?
Acinar type cells (And rarely - large duct, trans cell, small cell, mucinous)
Basically carcinoma in situ of the prostate. Hasn't broken the BM.
Which HPV strains cause squamous cell carcinoma?
HPV 16, 18
Where in the prostate does cancer usually develop?
Name 3 penile in situ lesions
