Cystitis, Pyelonephritis, Prostatitis, Urinary Stones (Tyler) Flashcards
Cystitis DDx
Pyelonephritis
Urethritis
Vaginitis
Prostatitis
Asymptomatic bacteriuria (ASB)
Interstitial cystitis
Pelvic inflammatory disease (PID)
Urinary calculi
Radiation or chemical cystitis, e.g., cyclophosphamide
Bladder cancer
Urinary incontinence
ASB
asymptomatic baceriuria
when is a diagnosis of ASB made?
only when the pt does not have local or systemic symptoms referable to the urinary trct
bacteria is usually detected incidentally when patient undergoes screening urine culture for unrelated reason
cystitis common sx
dysuria
urinary frequency
urgency
elderly patients often present with cystitis how
asymptomatically because their immune system is weak and they fail to mount a response
what is the main thing that differentiates cystitis from pyelonephritis
fever, with pyelonephritis
fever of pyelonephritis
high spiking ‘picket fence’ pattern and resolves over 72hr of therapy
bacteremia develops in 20-30% of cases
patients who have pyelonephritis with diabetes may present how
with obstructive uropathy associated with acute papillary necrosis when the sloughed off papillae obstruct the ureter
when is papillary necrosis common besides DM
sickle cell
analgelsic nephropathy
obstruction
emphysematous pyelonephritis
severe form of pyelonephritis that is associated with production of gas in renal and perinephric tissue that basically only happens in diabetic patients
common complication of pyelonephritis
intraparenchymal abcess formation
acute bacterial prostatitis presents how
dysuria
frequency
and pain in perineal area
fever and chills are usually present and often patient complains of pressure or pain in perineal pain
chronic bacterial prostatitis presents
more insidiously as recurrent episodes of cystitis
sometimes with associated pelvic and perineal pain
men who present with recurrent cystitis should be evaluated for a prostatic focus as well as urinary retention
complicated UTI
presents as a symptomatic episode of cystitis or pyelonephritis in a man or woman with an anatomic predisposition to infection, with a foreign body in the urinary tract, or with factors predisposing to a delayed response to therapy
why does heart failure present with nocturia
HF can lead to reduced renal perfusion during the day while patient is upright, when you lie down it normalizes, creating diuresis
Urinary Stone Disease essentials of diagnosis
severe flank plank
nausea and vomiting
identification on non-contrast CT or US
Urinary Stone Disease general considerations
M:F 2.5:1
incidence is greatest during summer months
contributing factors to urinary stone formation
3rd and 4th decades
Urinary Stone Disease genetic factors
Cystinuria
Distal renal tubular acidosis
High protein and high salt intake
Persons in sedentary occupations have a higher incidence than manual laborers
Increasing evidence is revealing that urinary stone disease may be a precursor to subsequent cardiovascular disease
five major urinary stones
Calcium oxalates
Calcium phosphate
Struvite (magnesium ammonium phosphate)
Uric acid
Cystine
calcium stones are
radiopaque
uric acid stones are
radiolucent
hyperuricosuric calcium nephrolithiasis
is secondary to dietary excess or uric acid metabolic defects
Hypercalciuric calcium nephrolithiasis
can be caused by absorptive, resporptive, and renal disorders
hyperoxaluric calcium nephrolithiasis
usually due to primary intestinal disorders including chronic diarrhea, IBD, and steatorrhea
